Over deze norm
Specifies the characteristics of the fitness for purpose of glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (GRP-UP) piping systems intended to be used in underground drainage and sewerage under pressure. It also specifies the relevant test parameters for the test methods referred to in this Standard. It is applicable to the joints to be used in GRP-UP piping systems to be used for the conveyance of surface water or sewerage under pressure below ground, outside buildings, at temperatures up to 50°C. This standard specifies initial performance requirements for the following joints for use with GRP-UP pipes for buried pipelines or pipework systems as a function of the declared nominal pressure rating of the pipeline or system: a) flexible socket-and-spigot or mechanical joint; b) reduced articulation socket-and-spigot or mechanical joint; c) rigid locked socket-and-spigot joint; d) cemented socket-and-spigot or butt joint; e) bolted flange and threaded joint. This standard is applicable to joints which are or are not intended to be exposed to end thrust loads in service. It covers requirements to prove the design of the joint. Tests referred to in this standard are suitable for evaluating joints intended for use at temperatures up to 50°C and may be applicable for joints for use at higher temperatures.
