The voluntary certification scheme for plastic multilayer piping systems for hot and cold drinking water inside buildings is a joint effort of two key European organizations. It was initiated in close cooperation with the Brussels based European trade association of plastic pipe and fittings manufacturers, TEPPFA. Efforts include a signed Memorandum of Understanding (MoU) by the administrators of the voluntary certification for plastic piping systems for hot and cold drinking water inside buildings in March 2018. It marked the beginning of the voluntary assessment program in Europe in multilayer piping systems - an effort to realize a transparent and harmonized certification scheme for plastics multilayer hot and cold drinking water pipe producers. The scheme is open; all individual European certification bodies and their associated test houses can join.
The pilot standard used in introducing the scheme is the ISO 21003, “Plastics piping systems — Multilayer pipes and their joints, based on thermoplastics, for water supply”/1/ and certificates have already been issued to key international plastic pipe producers. The ISO 21003 standard includes polymeric layers made of polybutylene (PB), polyethylene (PE), crosslinked PE (PEX), polypropylene (PP) or PVC-U. Pipe sizes covered are size group one and two: up to and including Ø63mm
The mutual recognition also includes the audit testing performed by the testing laboratory on behalf of the certification body. The minimum frequencies are once per year per dimension group.
The ongoing work on further developing the system includes introducing of more test laboratories next to as well as introducing more products and standards to be implemented as part of the certification scheme. The end result will be a transparent, harmonized and efficient certification scheme for the players on the European plastics pipe market.
