Plastics piping systems for hot and cold water installations - Polyethylene of raised temperature resistance (PE-RT) - Part 1: General (ISO 22391-1:2009, MOD)
This Malaysian Standard specifies the general characteristics of piping systems made of
- 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) and for heating systems, under specified design pressures and temperatures appropriate to the class of application.
This Malaysian Standard covers a range of service conditions (classes of application), design pressures and pipe dimension classes, and also specifies test parameters and defines terms. In conjunction with the other parts, it is applicable to PE-RT pipes, fittings, their joints and to joints having components of PE RT, as well as of other plastics and non-plastics materials, respectively, used for hot and cold water installations.
