Plastics piping systems for hot and cold water installations - Polyethylene of raised temperature resistance (PE-RT) - Part 3: Fittings (ISO 22391-3:2009); German version EN ISO 22391-3:2009
This part of DIN EN ISO 22391 specifies the characteristics of fittings for piping systems made from polyethylene of raised temperature resistance (PE-RT), Type I and polyethylene of raised temperature resistance (PE-RT), Type II intended to be used for hot and cold water installations within buildings for the conveyance of water - whether or not the water is intended for human consumption (domestic systems) or heating systems - under the design pressures and temperatures appropriate to the class of application according to DIN EN ISO 22391-1. It covers a range of service conditions (classes of application), design pressures and pipe dimension classes, and also specifies test parameters and test methods. When used in conjunction with the other parts of DIN EN ISO 22391,
