A2.0 Transitional provisions (WaterMark Certification Scheme)

A reference in A2.1(b)(i) to the WaterMark Certification Scheme is a reference to the WaterMark Certification Scheme including the provisions of Part G1 of NCC 2015 Volume Three until such time as the publication by the administering body of scheme rules which replace those provisions.

A2.1 Suitability of materials and products

(a)

Every part of a plumbing or drainage installation must be constructed in an appropriate manner to achieve the requirements of the NCC, using materials and products that are fit for the purpose for which they are intended.

(b)

For the purposes of (a), a material or product is fit for purpose if it is—

(i)

listed on the WaterMark Schedule of Products, certified and authorised in accordance with the WaterMark Certification Scheme; or

Fit for purpose

A2.1(a) requires that each plumbing or drainage installation meets the requirements of the NCC, and that all materials and products used are fit for their intended purpose. The clause only applies to materials and products within the scope of the requirements of Volume Three of the NCC.

A2.1(b) provides two means of establishing that a material or product is fit for purpose. These are (i) that the material or product is certified and authorised under the WaterMark Certification Scheme, or (ii) that it is an 'excluded product'. Excluded products may be any product deemed not to require certification under the WaterMark Certification Scheme.

A2.1(d) requires that, notwithstanding (b), where a material or product is to be used in contact with drinking water, it needs to pass the relevant test set out in AS/NZS 4020.

In any case, evidence must be provided to support a claim that the material or product is fit for purpose. The acceptable forms of evidence which can be used are provided at A2.2.

New or innovative products

Under the rules of the WaterMark Certification Scheme, any material or product which is new or innovative, and that is not listed on either the WaterMark Schedule of Products or the WaterMark Schedule of Excluded Products, needs to be assessed and, if required, certified and authorised in accordance with those rules prior to its use in a plumbing or drainage installation.

Details of the WaterMark Certification Scheme, including the scheme rules, the WaterMark Schedule of Products and the WaterMark Schedule of Excluded Products are explained in Section G and on the ABCB website at www.abcb.gov.au.

A2.2 Evidence of suitability

(a)

Evidence to support that a material or product subject to A2.1(b)(i) has been certified and authorised must be in the form of a WaterMark Licence.

(b)

Evidence to support that any other material or product, or a design, form of construction or installation, meets a Performance Requirement or a Deemed-to-Satisfy Provision may be in the form of one or a combination of the following:

Tas A2.2(b)(i)

(i)

* * * * *

(ii)

A report issued by a Recognised Expert or a Registered Testing Authority showing that the material, product, design, form of construction or installation has been submitted to the tests listed in a report, and setting out the results of those tests and any other relevant information that demonstrates its suitability for use in the plumbing or drainage installation.

(iii)

A certificate from a professional engineer or other appropriately qualified person which—

(A)

certifies that a material, product, design, form of construction or installation complies with the requirements of the NCC; and

(B)

sets out the basis on which certification is given and the extent to which relevant specifications, rules, codes of practice or other publications have been relied upon.

(iv)

Any other form of documentary evidence that correctly describes the properties and performance of the material, form of construction or installation and, as required, demonstrates its suitability for use in the plumbing or drainage installation.

(c)

Any copy of documentary evidence submitted must be a complete copy of the original report or document.

Explanatory information

Products subject to WaterMark certification

A2.2(a) clarifies that the only acceptable evidence of suitability for materials and products subject to certification and authorisation under the WaterMark Certification Scheme is a WaterMark Licence. Refer to Section G for further explanatory information.

Products not subject to WaterMark certification

For any material or product not subject to certification and authorisation under the WaterMark Certification Scheme, the acceptable forms of evidence of suitability are provided in A2.2(b). These are broad ranging, and the authority having jurisdiction must be satisfied that the evidence provided is suitable for the material or product being installed.

Suitability of design, construction and installation

For a design, form of construction or installation, evidence which can used to support a claim that a Performance Requirement or a Deemed-to-Satisfy Provision has been met is also provided in A2.2(b).

In A2.2(b), the same evidence can be used to support materials and products as well as design, construction and installation because in both cases it is the Performance Requirements or Deemed-to-Satisfy Provisions of the PCA which need to be met.

Note: When determining which form of evidence will be used under A2.2(b), it is important to consider the appropriateness of the evidence to the claim, as some evidence may be more suited to installations, and others to materials and products.
