Plastics piping systems for the supply of gaseous fuels for maximum operating pressures up to and including 2 MPa (20 bar). Polyamide (PA) - Code of practice for design, handling and installation Ingestion-build-141043 to avoid unintended fluid movement1 Scope This part of ISO 22621 specifies a code of practice dealing with polyamide (PA) piping systems, intended to be buried outside buildings and used for the supply of gaseous fuels. It is applicable to mains and service lines, the components of which are prepared for jointing by scraping and or machining, and gives instructions for the design, storage, handling, transportation, laying conditions and fusion quality control of PA pipes and fittings
