Plastics piping systems -- General rules for structural design of glass-reinforced thermosetting plastics (GRP) pipes -- Part 1: Buried pipes
ISO/TS 20656-1:2017 describes how partial factors for buried GRP pipes are developed, and are primarily intended to define the necessary safety measures for GRP pipes that meet the requirements of ISO 10639, ISO 10467 and ISO 25780, and EN 1796 and EN 14364. The same methodology can be utilised for other pipe product standards, although other parameters would apply.
