Introduction
The plastics pipes industry revolves around specifications and standards for the products and test methods to verify performance. Pipe systems are one of the most critical applications for thermoplastics materials with a design base of 50 years and expected lifetime in excess of 100 years. Products must be fit for purpose and the end user needs confidence in the product in order to specify them. Specifications and dimensions must be universal and methods of test need to be standardised. The industry has put in a great deal of effort over many years to develop reliable methods.
Product and test method standards are developed by CEN for Europe and ISO for global use. ISO/TC 138 and CEN/TC 155 Technical Committees are responsible for ISO and EN standards for plastics piping systems respectively. The TCs are split into Sub-committees and Working Groups for specific applications and test methods. It takes several years to develop a standard to publication and these are reviewed every 3 to 5 years and revised if required.
