Plastics piping systems. Multilayer piping systems for outdoor gas installations. Specifications for systems has-corrigendum Following BS EN 1022 test1 Scope This International Standard specifies general and performance requirements for multilayer pipe systems based on pipes made from thermoplastics and intended to be used for gas supply outdoors. It gives requirements for the design of pipe systems consisting of multilayer pipes based on thermoplastics and for which at least 60 % of the wall thickness is of a polymeric material. The polymeric material used for stress design layers and all inner
