High Stress Crack Resistant PE100 (PE100 HSCR) is a PE100 material which offers greater resistance to slow crack growth than regular PE100. This is particularly important where the pipe is prone to damage during installation.
This guideline discusses the existing techniques for non-destructive (NDT) and destructive testing of electrofusion (EF) and butt welding options for jointing polyethylene (PE) pipe systems. It provides acceptance criteria for nominated weld features. A section has also been included related to the emerging alternative NDT technologies and aspects to consider when interpreting some destructive weld tests.
The guidance provided in this document is based on pipe manufactured to AS/NZS 4130 and fittings made from compounds complying with AS/NZS 4131. These guidelines apply to both pipe and fittings used for the conveyance of water, and cannot be used for compressed air or gas applications.
