AS/NZS 3500 Series update

AS/NZS 3500 Series update

Standards Australia is the nation’s peak non-government standards organisation with a long lasting commitment to the development of Standards in the Water and Waste Services sector. Ron Pulido outlines what is happening in the market.

The AS/NZS 3500 series of Standards on plumbing and drainage has been currently under revision, with public comments on the new drafts closing in December 2017.

It should be noted that since these projects are still in the drafting phase these changes are subject to agreement within the Committee, and to compliance with the NCC protocol for the development of NCC Referenced Documents.

All drafts are released to the public as part of our transparent development process. Any interested individuals are encouraged to review the proposed changes and provide input on the document for the relevant Standards Australia technical committee to review.

AS/NZS 3500.5:2012 Plumbing and drainage – Housing installations

Following widespread consultation with key industry stakeholders, including the Australian Building Codes Board, AS/NZS 3500.5:2012 Plumbing and drainage – Housing installations, will be withdrawn with no future revisions planned by Standards Australia.

AS/NZS 3500.5 is a compilation of the other parts in the AS/NZS 3500 series. The withdrawal of Part 5 has no material impact on the requirements of these standards. It is important to note that a withdrawn standard is still available for purchase and use, and can still be referenced in a regulatory framework.

Working towards 2022 National Construction Code

Don’t wait! Start planning early and engage with stakeholders and Standards Australia now to submit a project for inclusion in the 2022 National Construction Code (NCC).
