Plastics piping systems -- Multilayer pipe systems for indoor gas installations with a maximum operating pressure up to and including 5 bar (500 kPa) -- Part 1: Specifications for systems

ISO 17484-1:2014 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 ISO 17484-1:2014.

ISO 17484-1:2014 gives guidance for the design of piping systems consisting of multilayer pipes based on thermoplastics, for which at least 60 % of the wall thickness is polymeric material. Polymeric materials intended for stress-designed layers and all inner layers are required to be polyethylene (PE) and/or crosslinked polyethylene (PE-X) in accordance with Annex A of ISO 17484-1:2014.

ISO 17484-1:2014 applies to systems that operate at temperatures of −20 °C up to +60 °C.

For the purpose of ISO 17484-1:2014, crosslinked polyethylene (PE-X) and adhesive layers are considered as thermoplastic materials.

For sizes greater than 63 mm the requirements of ISO 18225 have to be fulfilled in addition.

ISO 17484-1:2014 is applicable for piping systems used in buildings to supply gas with a maximum operating pressure up to and including 500 kPa (5 bar).

ISO 17484-1:2014 applies to the following fuels:

  • Category D gaseous fuel: natural gas;
  • Category E gaseous fuel: LPG vapour, and natural gas or LPG vapour.
