適用范圍：This International Standard specifies the properties of the piping system and its components made from glassreinforcedthermosetting plastics (GRP) based on unsaturated polyester resin (UP) for water supply, irrigation,drainage or sewerage systems with or without pressure.This International Standard is applicable to GRP-UP piping systems, with flexible joints, intended to beinstalled using jacking techniques. It specifies the characteristics of pipes made from GRP-UP, with or withoutaggregates or fillers and also specifies the test parameters for the test methods referred to in this InternationalStandard.NOTE Pipes referred to in this International Standard are, because of their intended use, required to have a minimumnominal stiffness of at least SN 20000 (see 5.2.1).This International Standard is applicable to pipes and joints with a size range from DN100 to DN4000 whichare intended to be used for the conveyance of water or sewage at temperatures up to 50 ℃, with or withoutpressure.It covers requirements to prove the design of the joint and specifies type test performance requirements forthe joints as a function of the declared nominal pressure rating of the pipeline system and the required jointdeflection capability of the system.GRP-fittings, used between pipe systems covered by this International Standard, shall be in accordance withISO 10639 for water supply systems or ISO 10467 for drainage and sewerage systems, as applicable. In apipe-work system, pipes of different nominal pressure and stiffness ratings may be used together.
