标准范围

This International Standard specifies the general requirements and the performance requirements formultilayer pipes based on thermoplastics intended to be used for water supply outside buildings, for buriedwater mains and services and for water supplies above ground.It gives guidance for the design of piping systems consisting of multilayer pipes based on thermoplastics or,for which at least 60 % of the wall thickness is polymeric material, and the inner layer in contact with water ismade of polymeric material.The polymeric layers used for the stress-bearing layers are selected from polybutylene (PB), polyethylene(PE), crosslinked polyethylene (PE-X), polypropylene (PP), chlorinated poly(vinyl chloride) (PVC-C) and unplasticized poly(vinyl chloride) (PVC-U).This document is applicable to piping systems used for the conveyance under pressure of cold water (up toapproximately 20 °C) for drinking. It is also applicable to piping systems for the conveyance of water (up toand including 40 °C) for general purposes.It applies where special functional requirements are needed.
