With over 50 PE-X systems available in Australia, the market is a mix of innovation and imitation.
Some are groundbreaking, while others are just cheap copies. So how do you separate the good from the bad?
At first glance, they may all look alike, but key differences—such as SDR ratings, pressure ratings (ie PE-X 100), material composition, applications, temperature ratings, fitting profile and DN range—set them apart.
Any PE-X pipe sold in Australia must conform to the minimum requirements of Australian Standard 3500.
However, there’s one thing they all have in common: every PE-X piping system must comply with Australian Standards. No system can gain WaterMark accreditation without meeting the minimum requirements set by AS/NZS 2492, the Australian Standard for Cross-linked polyethylene (PE-X) pipes for pressure applications.
Understanding PE-X Compliance in Australia
For a PE-X 80 product with an SDR of 11, Australian Standards require it to withstand at least 0.95 megapascals at 60°C for continuous service. Systems that exceed these benchmarks—such as PE-X 100—automatically comply because they surpass the standard.
The Australian Standard outlines the minimum requirements. If the SDR is higher, it still complies with the standard.
Keeping Up With Innovation & Certification
As PE-X technology evolves, we sometimes see Australian Standards lagging behind. This isn’t new, but it’s becoming more common as advanced piping solutions enter the market. While innovation is great for plumbers, it can also create confusion—especially when misinformation spreads.
At Austec, we’re ahead of the curve in product design. Our unique fittings and high-performance PE-X systems are built to add value to your work. But ultimately, it’s the certifying bodies that decide what meets Australian Standards. When in doubt, always refer to an official authority.
Who Decides What’s Compliant?
The plumbing gods of compliance—SAI Global—are responsible for issuing WaterMark accreditation. If a product doesn’t meet their standards, it cannot legally be installed in Australia.
There’s a lot of misinformation in the industry, so it’s always best to refer to an independent certifying body for definitive answers.
For professional and definitive guidance on compliance, we recommend checking with:
- SAI Global – The governing body for WaterMark certification
- PAG Consulting Services – Independent experts in PE-X regulations
