The piping system according to ISO 16422:2006 is intended for the conveyance of cold water under pressure, for drinking water and for general purposes up to and including 45 degrees Celsius, and especially in those applications where special performance requirements are needed, such as impact loads and pressure fluctuations, up to pressure ratings of 25 bar.
