Bibliography

Defines the required properties of the piping system and its components made from glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP) intended to be used for drainage or sewerage, including culverts, with or without pressure. In a pipework system, pipes and fittings of different nominal pressure and stiffness ratings may be used together.
