Transcript

Hello, my name is Tom Roberts,

and I'd like to welcome
you to the presentation

for the Plumbing Code
of Australia in 2019.

This presentation will provide an overview

of the changes to volume
three of the NCC in 2019.

A recording of the
seminar will be available

on the ABCB website.

Likewise, there will also be a copy of the

Building Code of Australia

and Standards Australia's
presentation as well.

In fact, all our seminars are available

on the ABCB website since 2016.

So if you or your colleagues
have missed a presentation,

feel free to review it there.

The seminar will probably cover

changes to the Plumbing
Code of Australia, or PCA,

which I'll run through first.

There's an overview for the
changes to referenced documents,

applicable to plumbing.

I'll provide you a bit of information

on the WaterMark Certification Scheme,

and I'll let you know about some areas

that the ABCB will be working
on for the next three years

in anticipation for NCC 2022.

So firstly, and most
importantly, you need to know,

is the adoption date for 2019.

The transition and the transition period

applicable to the PCA.

2019 NCC becomes the current Code

on the 1st of May this year, so 2019.

Every state or territory
has different legislation

covering the PCA.

So if you're not sure
which edition applies

for a specific project,
make sure you contact

your relevant state or
territory plumbing authority.

So the adoption of the 2018 edition of

the Australian, New Zealand Standard 4020

for the testing of products in
contact with drinking water,

has been provided for
transition period for 2019.

So this transition period
allows for the test reports

to be based on the 2005 edition of 4020,

to continue to be accepted
until the 1st of May 2024.

However, test reports prepared
after the reference date

of NCC 2019, so the 1st
of May 2019, must be based

on the 2018 edition of
the Australian Standard.

So the WaterMark administration

will also be releasing
a notice of direction

to provide additional
information on this transition.

One of the major projects
that ABCB is working on,

is readability.

The NCC is a complex document,

full of long sentences that
can be hard to understand,

so we've rewritten it,

made it into simpler a
language as possible.

One of the, The Plumbing
Code of Australia,

has the been the first to be
written under this project

and we're also adjusting the structure

to make it easier to understand.

As part of making the PCA more readable,

we've used exemption and limitation boxes.

These are used to separate the
content out of smaller parts

and make it easier to understand.

You'll also notice a new numbering system

for the first sub clause.

There is a number rather than a letter.

The problem is we've been
using this numbering system

and we're also working on having volumes

one and two, also replicate
this numbering system.

This will produce a consistent structure

across all volumes of the NCC.

So, in summary, all the
technical content will stay

the same, but the
structures and the content

will be more readable and easy to use.

So moving on to the changes
the the Plumbing Code,

so we'll start with Section A,

the Governing Requirements.

So it was found that in
fact there's three different

volumes of the Code and
three different structures,

which was making it very
difficult for practitioners

to use different volumes of the Code.

So here's the first step
toward the common structure,

which is found in 2019.

On the left you will
see Section A of the PCA

for 2016 and for NCC 2019,
in that all three volumes,

will now share a common Section A.

Section A contains information
about how to use the NCC,

what a performance solution is,

what building classifications are,

and all the governing requirements

as we could now call them.

So the governing requirements of the NCC

provide the rules and
instructions for using

and complying with the NCC.

And I said, all three volumes now contain

a consistent structure and
also consistent schedules.

So the first schedule to contain,

contains the appendices of each state

and territory for that volume.

Every variation in singles,
already appendices at the back

of each volume and has been combined

to create a common schedule.

There's also definitions and a
list of referenced documents,

contained for all three
volumes of the NCC.

Schedule five, six and seven
have also been included

to be consistent across all three volumes,

however, primarily relate to building.

Here's an example of new Schedule Three,

which contains NCC defined terms.

It's now at the back of each volume

and you can see all
definitions from all volumes.

As you can see on the slide,

some definitions may be familiar with,

and relate to plumbing terms,

and others you might
not be as familiar with,

because they relate to the
defined terms of the PCA.

So in the following section we will cover

the main changes to
Section B, Water Services.

Firstly we'll start on part
B2, Heated Water Services.

Firstly, performance requirement
BP2.5 legionnaires control.

This performance current
states that heated water

must be stored and
delivered under conditions

which avoid the likelihood
of bacterial growth.

One of the ways compliance
can be verified,

is for the use of
verification method BV2.2,

Heated Water Storage Temperature.

This method verifies the growth
of legionnaires is avoided,

in the heater water system,
when the water heater

is designed as such that
the water will be subject

to temperature dependent
minimum exposure periods.

For example, BV2.2, shows that a minimum,

at a temperature of 70 degrees or greater,

is the minimum exposure
period for one second.

And at 66 degrees, two minutes,

and at 60 degrees, 32 minutes.

So there are the timeframes required

to avoid the likelihood of
legionnaire bacterial growth.

It's important to remember
that this verification method

is used only when undertaking
a performance solution

and is only one of the
methods to actually verify

the compliance with this
performance requirement.

So there's also new deem
to satisfy provisions.

So B2.5, Maximum Delivery Temperature.

So this deem to satisfy requirement,

may look familiar to some.

So this provision applies to only

new heated water
installations for the purpose

of personal hygiene and states
that the delivery temperature

of the heated water at the
outlet of each sanitary fixture,

must not be more than 45 degrees Celsius

in any aged care building,
health care building,

early childhood centre,
primary or secondary school

or a designated accessible facility.

And, of course, not more
than 50 degrees Celsius

in all other cases.

The next edition to part B2, is part B2.6,

Temperature Control Devices.

So also for a new heated
water installations only,

this provisions outline
acceptable temperature control

devices for each outlet
temperature limitation.

So this is linked to the previous clause,

which outline delivery temperatures,

which was previously discussed
and requires the delivery

of not more than 45 degrees
Celsius at the outlet.

So the provision states
that the water temperature

at the outlet in these
situations, must be controlled

by either a thermostatic mixing valve

or a thermostatically controlled tap.

The next edition to part B2 is B2.6,

Temperature Control Devices.

Also for new heated
water installations only,

these provisions outline
acceptable temperature control

devices, for each temperature limitation.

Linked to the previous clause,

which outlines the delivery temperatures,

these provisions describe the
temperature control devices

which are an acceptable means
to deliver those temperatures.

These provisions state
that the water temperature

at the outlet in these situations,

must be controlled by a
thermostatic mixing valve

or a thermostatically controlled
tap for those temperatures

that makes it to 45 degrees Celsius.

Similarly, B2.6.2 applies to B2.5.1b,

which requires the delivery of not more

than 50 degrees Celsius at the outlet.

This provision states
that the water temperature

at the outlet, must be
controlled by either

a thermostatic mixing valve,

a thermostatically controlled tap,

a tempering valve or a
temperature limited water heater.

As new technologies are
introduced to the market place,

there may be additional
means for delivering

water temperatures that meet
the performance requirements

in B2.2.

These performance requirements
relate to the delivery

of tap water, from
fixtures and appliances,

at a temperature which
is unlikely to scold.

Although new product types
are not listed in this clause,

a performance solution may be utilised

to allow them to be installed.

So for more information on how to develop

a performance solution,
visit the ABCB website.

General deem to satisfy requirement B2.9,

references AS/NZS 3500 part four,

for the installation of
heated water services.

In association with this provision,

a new note has been included.

This note states there
is no deem to satisfy

provisions for warm water systems.

This has been included in
PCA 2019 to ensure that

practitioners that are aware,
that a performance solution

must always be undertaken
when installing or designing

a warm water system and that there is

no deem to satisfy solution available.

The next part of B is part B4,
Fire fighting Water Services.

So changes to this part
were primarily the result

of a proposal for change,
similarly to the ABCB.

The amendments apply to part B4.2,

which provides general
deem to satisfy provisions

for fire fighting water services.

The main amendment to this part,

is the reference to two new
FPAA technical specifications.

For fire fighting sprinkler systems,

which can be used instead of a system

that is fully complies with AS2118.

The new technical specifications
are FPAA101H and FPAA101D.

For those who may not
be familiar with FPAA,

FPAA stands for Fire Protection
Association of Australia.

They are the national
peak body for fire safety

and provide information services education

to the fire protection
industry and the community.

It is also important to remember that

the fire fighting water
services for class 2

to non buildings, must comply with part E1

of the NCC in volume one.

So these new technical specifications.

Technical specifications FPAA101H,

is for automatic fire sprinkler
design and installation

for hydrant water supply.

This technical specification specifies

the minimum requirements
for the components,

design, installation, commissioning

of a combined fire hydrant
and fire sprinkler system

for buildings which have a rise in stories

of four or more and
are less than 25 metres

in effective height and contain class two

and class three parts.

This system is referred to, commonly,

as the FPAA101H system.

Technical specification 101D,

automatic sprinkler system
design and installation

for drinking water supply.

So this technical specification specifies

the minimum requirements
of components, design,

installation, commissioning,
of a fire sprinkler system

for a building which has a
rise in story of four or more,

has less than 25 metres
in effective height,

contains class two and three parts,

and this system is supplied
from the building's drinking

water supply system and
is commonly referred to

the FPAA101D sprinkler system.

So FPAA undertaking a national
awareness seminar series,

which will be providing
information to practitioners

looking to use these systems and will also

be providing ongoing training to designers

and installers wishing to use them.

So keep an eye out for any
related information on this.

So one of the major amendments
to water services section,

is an inclusion of a new part
B5, Cross Connection Control.

This part sets out
cross connection hazards

and the corresponding hazard ratings

and has been included as
one of the recommendations

of the backflow prevention
research report.

The report was the outcome of one of ABCBs

Plumbing Code Development
Research projects.

The lack of many other parts of the PCA,

it starts with a performance requirement.

So BP5.1, Contamination Control,

states that a water service
must be designed, constructed,

and installed to avoid
contamination to the water service

type it applies to.

So the performance requirements is used

but a performance solution
is being undertaken.

However where deem to satisfy
solution is being used,

this performance requirement is comply

with by using the deem
to satisfy solution.

So B5.2, is for Cross Connection Control.

So sub clause one states
that a hazard exists

wherever it is possible
for contaminants to enter

the drinking water service or supply

by a potential cross connection.

Sub clause two states that each hazard

must be assigned to an
individual hazard rating

or zone hazard rating and be isolated

from the drinking water service

by an appropriate backflow
prevention device.

Sub clause three, states
that where a site is serviced

by a network utility operator's
drinking water supply,

an appropriate containment
protection must be selected

and installed.

So a network utility operator
is defined by the NCC.

So for this application, it means a person

who undertakes the pipe
distribution of drinking water

or a non drinking water supply.

The network utility operator
is a water authority,

which is licenced to supply water

and may be a licenced utility,

local government or a council.

Part B5.3, the Cross connection Control

of Non drinking Water Services.

This provision states that a hazard exists

wherever it is possible
for water or contaminants

to enter the non drinking
water supply or service

via any potential
cross connection between itself,

another separate
non drinking water service,

on the same side.

A separate non drinking
water service means

one that is, draws water
from different source.

For example, a site connected to both

recycled water and rain water.

Both are non drinking water services,

but are joined from separate sources.

Therefore, each would require separate,

non drinking water service.

Each hazard must be assigned
a containment hazard rating,

a contaminant hazard rating in accordance

with hazard specification
B5.1 and be isolated

from the non drinking water
service by appropriate means

of protection, which
is selected and stored

and accordance with AS/NZS 3500 part one.

B5.4, is for Cross connection Control

for Fire fighting Water Services.

It states that each
fire fighting water service

must be assigned a hazard
rating and be isolated

from the drinking water service

by an appropriate backflow
prevention device.

A number of new deem to satisfy provisions

reference specification B5.1
Cross connection Hazards.

This specification outlines
the protection types

and hazard ratings used
for individual protection

at the point of each individual hazard,

zone protection at the point
where a group of hazards

can be isolated, hazards
posed by the site to

the network utility operator's
drinking water supply,

and for fire fighting water services.

The hazard ratings prescribed
in the specification,

must be used for selecting
the required backflow

prevention device for the
purposes of compliance

with the deem to satisfy provisions.

So this specification only
prescribes hazard ratings

for a limited list of known hazards.

It does not cover every
potential cross connection

that may arise from time to time.

When a situation arises that is not listed

in this specification, an
appropriate hazard rating

may be determined for
a performance solution.

In some jurisdictions,
regulations on their water supply

legislation, and or the rules set out

by the network utility operator,

may prescribe containment protection

which may differ from this specification.

So if this occurs, then those
regulations and or rules,

should then be followed in
place of this specification.

The specification only
applies to the purposes

of compliance of NCC volume three,

and is not intended to limit or extend

the application of any other regulations.

And the last part of Section B is part B6,

Rainwater Harvesting and Use.

The rainwater harvesting system
is defined within the NCC

as the plumbing
installation that comprises

of any plumbing that
connects to a rainwater tank

and to any drinking water or
non drinking water outlets

in any top up line that
conveys drinking water

from the network utility
operator's water supply,

to a rainwater tank.

So this part has been
included as an outcome

of the rainwater harvesting
in use research report,

which provided recommendations
on a national approach

for rainwater harvesting.

The report is an outcome
of the ABCB's Plumbing Code

Development Research project.

In this part, there are four
performance requirements,

which cover stored rainwater,

rainwater harvesting system installations,

rainwater services and identification.

So performance requirement BP6.1, to BP6.4

are satisfied by complying
with DTS provisions

from B6.2 to B6.5.

Well B6.1 outlines that
application of the DTS provisions,

6.2 covers the collection of rain water,

6.3 primarily references
B1 for cold water services,

for the installation of the top up lines,

B6.4 outlines the requirements for buried

and partially buried rainwater tanks.

And B6.5 is for rainwater
pipe work in outlets

and covers the
installation, identification

of rainwater pipe work and outlets.

Section D is for Excessive Noise.

This is a new section within
the Plumbing Code of Australia

and however, the provisions
may look familiar to some

users of the PCA.

This section has been created as a result

of harmonisation work between both

the Building Code of Australia

and the Plumbing Code of Australia

and has also consolidated
a number of requirements,

which were often repeated
throughout numerous sections

of the Plumbing Code.

Section D sets out the
requirements to prevent

excessive noise being
generated from a plumbing

or drainage system that
could cause illness,

loss of amenity to
occupants in the building.

So in this part, there are
two performance requirements,

which cover undue and excessive noise.

So this performance requirement
states that a plumbing

or drainage system must be designed,

constructed and installed in a manner

that does not create undue noise.

They also state that a
plumbing or drainage system

must be designed to reduce
the transmission of airborne

or impact generated sound,
which may cause illness

or loss of amenity to the occupants.

So the performance requirement
only applies to a plumbing

or drainage system that is
located in separating wall

for a class one building or a class two,

three or 9C building that is
required to be sound rated.

Remember though the
building classifications

are outlined in the NCC.

Performance requirement
BP1.2 sub clause two,

states that the required sound insulation

of a floor or wall,
must not be compromised

by the incorporation or penetration

of a plumbing or drainage system.

It is also important to note that part F5,

in volume one of the NCC,

contains performance requirements

which covers sound
transmission and insulation

in walls and floors of class
two, three and 9C buildings.

Similarly, volume two of the NCC

contains performance requirements

which cover the sound insulation of walls

in class one buildings.

So the deem to satisfy
provisions for this section

are quite simple.

In order to prevent undue
noise, D1.2 provides provisions

regarding plumbing or drainage systems

to comply with the
relevant part of the PCA.

For example, B1.4, for cold water systems,

and C2.4 for sanitary drainage systems.

It also is required to
insulate occupants from sound

created from plumbing or drainage systems,

in certain classes of buildings.

B1.3 requires appropriate sound insulation

between sole occupancy units,

flexible couplings for
connections to pumps,

and requirements around systems

which pass through or is
located in separated walls.

So this slide shows a
number of these provisions

as are examples from
extracts from the Code.

Next we'll move on to new
Section E, for Facilities.

Again, first we'll look at
the performance requirements

of Section E and for this one,

there's only one performance requirement.

This performance requirement states

that while plumbing and
drainage system is provided,

supply taps or other operational controls

must be accessible and suitable for use.

The performance requirements
may look familiar

to some of the users of the PCA

and that is because it
is simply being relocated

into one stand alone section of the Code

and reduces the duplication
throughout numerous

sections of the PCA.

So the deem to satisfy provisions,

which can be used to satisfy
performance requirements BP1.1,

are outlined in E1.2.

E1.2 states that where a supply tap

or other operational controls are provided

in sanitary facilities,
for people for disability,

they must be in accordance
with AS1428, parts one and two.

As you can see on the slide,

there are two different
editions of 1428 part one.

The 2011 edition must be
used for passenger use areas,

of class 9B and class 10
public transport buildings.

And the 2009 edition can
used for all other buildings.

It is important to note
that volume one of NCC

sets out the requirements for
the design and construction

of sanitary facilities in class
1B, 1A, 2 and 9 buildings.

A number of sections have been
removed from the PCA in 2019.

These include storm
water drainage systems,

hidden ventilation and air conditioning

and onsite waste water systems.

They've been removed because
the majority of the states

and territories around Australia,

did not adopt these sections.

And for the jurisdictions that did,

they've simply been relocated to the state

and territory appendix,
which is now contained

in schedule one, the stating territory

variations and additions.

There's also been a
substantial amount of change

to the documents referenced in the PCA,

including the 2018 editions
of the AS/NZS 3500 series.

So this table provides an
overview of the amount of change

to referenced documents in 2019.

There are two new referenced documents,

which are the FPAA
technical specifications,

which I mentioned before.

There have been four documents
which have been modified.

These include the AS/NZS
4020, testing of products

in contact with drinking water

and AS/NZS 3500 parts one, two and four.

There have been 31 deleted references

from the NCC, volume three.

So this has probably been the result

of those removed sections from the PCA

and includes documents
such as AS/NZS 1546,

onsite waste water
treatment units and AS 1668,

the use of mechanical ventilation

and air conditioning in buildings.

So the reference to AS/NZS 3500 part 5

has also been removed.

This means that the Standard
can no longer be used

in the AS/NZS 3500,

parts one, two and four,

must now be used for all
classes of buildings.

So it's important to note that
this list does not include

documents referenced
between NCC schedules,

such as schedules three, defined terms,

and an extensive list of
NCC referenced documents

and their editions can be found
in schedule four of the NCC.

So as mentioned, there's been a number

of modified referenced documents

and one of those major revisions

was to 3500 part one, 2018.

So 3500 part one covers water services

and the changes to the Standard
cover backflow prevention

and fire services,
requirements for the protection

of plastic pipes and fittings in contact

with direct, installed in direct sunlight.

Changes to non drinking
water services section

of the Standard, and some
minor changes as a result

of the inclusion of circulatory
heated water systems,

which is being made to 3500 part four.

There's also been a
clarification in jointing methods

and some minor technical
changes to address

some previous concerns
relating to other projects.

For AS/NZS 3500 part two,
sanitary plumbing and drainage,

the revision covered a range
of sanitary drainage topics,

but the major projects
related to the inclusion of

structural plastic, relining of drains,

and the protection of
plastic pipes and fittings

installed in direct sunlight.

The revision of 3500 part three, 2018,

stormwater drainage, was
undertaken to respond to changes

in practise and technology.

So some of those changes
include the inclusion

of siphonic drainage, rainwater
tanks, bio filtration,

updates to formulas and rainfall maps

and addresses new stormwater
drainage technology.

It should be noted that
AS/NZS 3500 part three,

is now only referenced by
volume one and two of the NCC

and not by the Plumbing Code of Australia.

The revision to AS/NZS 3500
part four, heated water,

incorporates changes to the provisions for

heated water circulatory systems,

protection of plastic pipes and fittings

installed in direct sunlight again,

a clarification on jointing
methods and the inclusion

to the reference to
thermostatically controlled taps,

allowing their use as a
temperature control device.

So there's also an amendment
made to the Standard,

with changes to clause 6521,
to provide additional option

for the orientation of
solar water heaters.

So that concludes the
changes to the PCA in 2019

but I'd also like to highlight
a few key points regarding

the WaterMark Certification Scheme,

which are as important to use as the PCA.

So firstly, it's important
to note that not all products

require WaterMark's certification.

However, all plumbing
products and materials,

used in a plumbing or
drainage installation,

require a risk assessment.

So this risk assessment would determine

whether or not WaterMark
certification is necessary.

So this document, the
WaterMark Schedule of Products,

lists products which have
been predetermined to require

WaterMark certification.

This document, the WaterMark
Schedule of Excluded Products,

lists products that have been
predetermined to be excluded

from the WaterMark Certification Scheme.

To ensure the materials
and products are still fit

for purpose, there is listed
on the WaterMark Schedule

of Excluded Products, must be supported

by evidence of suitability.

This is in accordance with A2.2

of the Plumbing Code of Australia,

whereas it's being used in a plumbing

or drainage installation.

So one option to demonstrate
whether the product

is suitable, is compliance with one

of the specifications listed.

Where the product is
excluded from requirement

certification, and includes
integral components

that are listed on the
WaterMark Schedule of Products,

each of those components must
be individually certified.

And lastly, the WaterMark database.

So the WaterMark Product
Database lists products

that have been certified and
marked in accordance with the

requirements of the WaterMark
Certification Scheme.

These products are recognised
by plumbing regulators

as being authorised for use in a plumbing

or drainage installation
and you can search

by either WaterMark licence
number, licencee names,

product specifications, the
product type, the brand name,

the model name or even
the model identification.

So filters enable you to
find searches for the product

and from the search
results, you can select

a specific category, certificate, product

and view the detailed information.

To support the use of the database,

a YouTube clip using the product database,

has been developed.

The clip provides an
overview of how to search

for certificates and products,
download key information

and what you do if you can't find

a plumbing material or
product on the database.

And lastly, in this section
of the presentation,

I'd like to give an
overview of what the ABCB

will be working towards in 2022.

So some of the major projects the ABCB

will be reworking over the
next few years in preparation

for NCC 2022, include
digitization, education materials,

Plumbing Code development
research and quantification,

the potential for a Gas
Fitting Code of Australia,

and an analysis on the costs and benefits

of moving to reduce or eliminate
lead in plumbing products.

So firstly we'll go on to digitization.

So digitization improvements
are being made to enhance

access and understanding of the NCC

for a range of new technologies.

The initiative will focus
on major improvements

to the NCC online, but
work is being undertaken

to ensure that a digital
NCC is able to be integrated

with other systems.

But what does that all mean?

So what if NCC could integrate
with other online systems?

So the ABCB is involved
with a number of projects

with Standards Australia
Incubator Programme,

and that is to explore other areas

where innovation is possible.

So one example of this investigation

is a digital glossary
of construction terms,

which combines all the
definitions from the NCC,

referenced Australian
Standards, and handbooks.

So what if, similar to
NCC, you could stream

an Australian Standard
directly on to your phone?

So again, Standards
Australia has been working

towards exploring this question

and are now piloting a digital version

of AS/NZS 3500 part two, 2018.

Now, what if all these documents

could interact with each other?

For example, NCC referenced documents

such as Australian Standards,

and the reference to
that document is a link,

which takes you directly to
the section of the Standard

that is being referenced.

Additional benefits, over
the traditional PDF versions,

include enhanced searches,
hyperlinks to other documents,

downloadable table of
contents, responsive tables

and figures and links to other resources,

which is an important part
of providing additional

guidance on the requirements of the Code.

So all this work is in
its very early stages

and a number of the
Standards Australia projects

are only proofs of concept at this time.

But as you can see on the slides,

this investigation into what
is possible in a digital world,

is going to be of great benefit
to the users of the PCA.

The resource library on
the ABCB's website contains

all ABCB resources, including
consultation documents,

non monetary handbooks,
ABCB standards, tools,

calculators, videos,
awareness resource kits,

and other publications.

So keep an eye out for free new handbooks,

which are in development.

These handbooks are covered topics such

as cross connection control,

warm water systems and
rainwater harvesting and use.

So the ABCB is always
upgrading existing materials

to ensure that they are up
to date as well as developing

new and other types of education material.

You may also see ABCB
staff supporting a number

of plumbing events around
the country in the future.

So the ABCB has an ongoing
projects to conduct research

to contribute to the future development

of the Plumbing Code of Australia.

So this includes continuing investigations

into new and innovative
methods of sanitary plumbing

and drainage pipe sizing,
as well as the development

of a verification method and calculators

for areas such as water
service pipe sizes.

So to address the COAG or Catalogue
of Australian Government's

decision to establish an NCC,

dealing with all onsite construction,

the ABCB will be working
on the feasibility

of the development of the gas
fitting component of the NCC,

which can be considered for NCC in 2022.

So this work is obviously subject

to the ABCB board approvals
and the building minister's

forum agreement but it is something

that would be of interest to plumbers

to undertake gas fitting work.

Also, in 2018, the ABCB commissioned

the Macquarie University to
conduct a literature review

to determine to what extent
plumbing products and materials

may contribute to lead levels
in excess of those permitted

by the Australian
Drinking Water Guidelines.

So this report is currently
available on the ABCB website.

And the ABCB will be continuing
to look into this area.

So we'll be undertaking a
regulatory impact statement,

on moving to a lower lead, or
lead free plumbing products

and this will include investigation

of the appropriate mechanisms,
options for synergy,

and the need for a transitional provisions

to enable industry adjustment,

in consultation with the key stakeholders.

This could be such as Standards Australia

and health and industry.

And that's a snapshot of
the work being conducted

by the ABCB in preparation for NCC 2022.

And that concludes our presentation.

Thank you for watching.
