Thermoplastics materials for pipes and fittings for pressure applications - Classification and designation - Overall service (design) coefficient (ISO 12162:1995)
This International standard constitutes the classification of thermoplastics materials in pipe form. It also defines the material designation, and gives a guide for a design base. The classification, the material designation, and the design base are founded on the resistance against internal hydrostatic pressure as derived from extrapolation, following ISO/TR 9080, to 50 years at 20°C in water.
