Plastic Piping Systems for Soil and Waste Discharge - with Noise Reduction Characteristics - Tubes, pipes and hoses, rigid: (HS code(s): 39172); Fittings, e.g. joints, elbows, flanges, of plastics, for tubes, pipes and hoses (HS code(s): 391740)

WaterMark Certification Scheme - WMTS-508:202x Plastic Piping Systems for Soil and Waste Discharge - with Noise Reduction Characteristics; (23 page(s), in English)

This Specification sets out the requirements for noise reduction pipes and fittings systems, either made of a compound of Polypropylene (PP) or Polyethylene (PE) and inert mineral additives.

Noise reduction pipes and fittings are designed for waste and drainage installations with a maximum continuous discharge operating temperature of 60°C and may be used at intermittent discharge operating temperatures up to 95°C. These pipes and fittings are for use in above ground waste installations inside buildings.

The proposed revisions for the 2025 version include the following:

(i) Scope expansion to include noise reduction piping made from Polyethylene (PE);

(ii) New definition for 'Intermittent' for products tested to this specification;

(iii) Technical requirements for noise reduction piping made from PE added to the body of the specification;

(iv) Marking requirements for the material compound (PP or PE) to be labelled on the product;

(v) Clarification that these products are for installation as an individual system and not to be combined other than for interconnection purposes (in accordance with AS/NZS 3500.2 Clause 10.13 and Table 10.13.1);

(vi) Inclusion of compliance Table A3 and A4

The Plumbing Code of Australia (PCA) requires that most products intended for use in plumbing and drainage installations in or around buildings to be evaluated and certified to WaterMark product specifications. WaterMark certification to an applicable product specification provides a process to evaluate and authorise products to enable their use in a plumbing and drainage installation. Thus ensuring that the plumbing and drainage products are fit for purpose for which they are intended.

This WaterMark Technical Specification (WMTS) was prepared in accordance with the Manual for the WaterMark Certification Scheme, Appendix 4, Protocol for Developing Product Specifications.

The objective of WaterMark Technical Specification is to enable product certification in accordance with the requirements of the Plumbing Code of Australia (PCA).
