AS/NZS 1260 PVC DWV Fittings

by

PVC gravity sewer systems have been in use in Australia since the early 1970s and are the predominant option for collection sewers up to size DN 375. Water industry consensus is that PVC-U gravity systems have performed satisfactorily and that correctly installed PVC-U systems have better resistance to tree root penetration, whether rubber ring jointed (RRJ) or solvent weld jointed (SWJ).  However, mechanical failures of some DN 100 and DN 150 injection moulded fittings with both rubber ring joints (RRJ) and solvent weld joints (SWJ), used within sewer property service connection assemblies, have been commonly experienced by Water Agencies for many years due to ground movement, subsidence and settlement related issues.

The Australian Standard for PVC-U pipe and fittings for drainage waste and vent applications is AS/NZS 1260:2017. A minimum wall thickness of 3mm for DN100 fittings and 4mm for DN 150 fittings is specified for injection moulded fittings. Tests indicate that fittings manufactured to the minimum requirements of AS/NZS 1260 have stiffnesses ratings between SN16 and SN80, depending on the size and configuration of the fitting. Clearly the ability of fittings to withstand ground movement is not related to their stiffness rating alone.

In response to Water Agency concerns  a limited range of “heavy duty” injection moulded fittings with additional wall thickness and in some cases additional strengthening ribs have been introduced to the market. These heavy duty fittings remain compliant with AS/NZS 1260 as the Standard specifies a minimum wall thickness only, however there are currently no guidelines for manufacturers or users to determine the definition of a heavy duty fitting and no industry consistency for clear identification of these fittings.

WSAA has amended their Product Specification WS PS 230 to allow an option for Water Agencies to specify heavy duty fittings. Minimum wall thicknesses for heavy duty fittings have been nominated based on Water Agency experience over the last 18 months or so and the requirement for a minimum stiffness rating for fittings has been removed.   The minimum wall thicknesses for heavy duty fittings have been nominated as RRJ DN 100: 4mm, RRJ DN 150: 5mm, SWJ DN 100: 5mm, SWJ DN: 150 6mm. (The additional wall thickness for SWJ is justified by their reduced joint flexibility). A requirement to mark the fittings “heavy duty” is also included.

ACCC Alert – COVID-19: Supplying and installing bidet products

by

See below notice from the ABCB.

The COVID-19 (coronavirus) pandemic has seen an increase in the purchase by those performing do it yourself tasks, of plumbing products such as toilet seat bidet douches, handheld bidet sprays and trigger sprays, and other bidet type products that are connected to toilet water supplies.

The Australian Competition & Consumer Commission (ACCC) has just published an alert, COVID-19: Supplying and installing bidet products on the Product Safety Australia website: https://www.productsafety.gov.au/news/covid-19-supplying-and-installing-bidet-products.

The ACCC has prepared the alert for suppliers and consumers in consultation with the ABCB.

The key message of the communique is that the installation of bidet products connected to the drinking water supply must be undertaken by a licensed plumber and hold WaterMark certification. The alert will also be posted on the ABCB website.

If you have any questions, please direct them to me.

Kind regards

Important Notice – AS/NZS 4130 Polyethylene (PE) pipes for pressure applications – January 2020 (update)

by

This is a follow up to post https://certmark.org/articles/2020/03/important-notice-as-nzs-4130-polyethylene-pe-pipes-for-pressure-applications-january-2020/

The WSAA Codes and Appraisals Group have met and included within their Agenda was a joint meeting with Mark Heathcote from PIPA to discuss the status and feedback relating to the recently introduced WSAA specification amendments to BRT procedures for AS/NZS 4130 PE pipe production. 

The outcome was that WSAA’s specifications were amended to extend the maximum frequency for OIT testing from 12 hours to 24 hours.

The revised Clause in WS PS 207 and WS PS 215 is now:

Clause 2 (c)

The manufacturer’s quality plan shall include within their  batch release test procedures a thermal stability test to ISO 11357-6 to be completed on a sample taken from the inside surface of the first pipe manufactured in a batch of a particular DN and PN and at an ongoing frequency not exceeding 24 hours of production for that pipe batch or when a new raw material compound is introduced.

Updated versions of the specifications can be accessed at: https://www.wsaa.asn.au/shop/product/35716    

Important Notice – AS/NZS 4130 Polyethylene (PE) pipes for pressure applications – January 2020

by

Prompted by a major PE pipeline failure in January 2019 the Water Services Association of Australia (WSAA), in consultation with The Plastics Industry Pipe Association of Australia (PIPA), has undertaken a review of its Product Specifications for Polyethylene pipe.   

WSAA considers that the requirements for recyclate and the current batch definition and Batch Report Testing requirements within AS/NZS 4130 need to be amended and will ensure a review of the Standard is undertaken through the Standards Australia process. 

In the interim the following Clauses have been inserted into WSA PS 207 and WSA PS 215. These specifications are available at: https://www.wsaa.asn.au/shop/product/35716.

Clause 2 (b)

The use of recyclate in pipe other than a manufacturer’s own clean in-house production for which full batch traceability is maintained, is expressly prohibited

Clause 2 (c)

The manufacturer’s quality plan shall include within their  batch release test procedures a thermal stability test to ISO 11357-6 to be completed on a sample taken from the inside surface of the first pipe manufactured in a batch of a particular DN and PN and at an ongoing frequency not exceeding 12 hours of production for that pipe batch or when a new raw material compound is introduced.
