Plastics piping systems. Multilayer pipe systems for indoor gas installations with a maximum operating pressure up to and including 5 bar (500 kPa) - Specifications for systems Ingestion-build-68772 1-Determination of lactose content in1 Scope This part of ISO 17484 specifies the general requirements and the performance requirements for multilayer pipe systems based on pipes, fittings and their joints intended to be used for gas supply within buildings. PE X and PE pipes composed of one stress designed layer, adhesive and a barrier layer are also covered by this part of ISO 17484. This part of ISO 17484 gives guidance for the design of piping systems consisting of multilayer pipes
