The following checks and tests are carried out as part of our product quality control system and to ensure the highest quality of products offered to our customers:
- All raw materials are sourced from approved suppliers and audited to ensure consistent parameters are maintained. In addition, the quality of our PE100 raw materials is also tested every seven months by an indepened testing authority in Netherlands to ensure that these materials comply with the enhanced requirements of the PE100+ Association.
- Comprehensive in-process and batch release checks ensure that all pipe, fittings and assemblies will deliver a system compliant with all relevant national, European and international controls, ensuring complete peace of mind for our customers.
- A range of checks and tests is carried out on both pipe and fittings (see below). We perform some of these on every product; others only need to be carried out on a sample basis.
- We keep detailed records of dimensional and performance tests for each production batch and every batch is given a unique identification number, providing customers with complete traceability.
