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.<\/p>\n
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.<\/p>\n
This part of ISO 17484 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 this part of ISO 17484. The outer layer of a metal multilayer is required to be PE or PE-X. PE-RT is considered as PE but with specific properties concerning hoop-stress performance (see 5.4.2.).<\/p>\n
NOTE The maximum operation pressure of PE 80 may be lower than 5 bar.<\/p>\n
This part of ISO 17484 applies to systems that operate at temperatures of \u221220 \u00b0C up to +60 \u00b0C.<\/p>\n
For the purpose of this part of ISO 17484, crosslinked polyethylene (PE-X) and adhesive layers are considered as thermoplastic materials.<\/p>\n
For sizes greater than 63 mm the requirements of ISO 18225 have to be fulfilled in addition.<\/p>\n
This part of ISO 17484 is applicable for piping systems used in buildings to supply gas with a maximum operating pressure up to and including 500 kPa (5 bar)1<\/sup><\/p>\n 1<\/sup> 1 bar = 0,1 MPa = 105<\/sup> Pa; 1 MPa = 1 N\/mm2<\/sup>.<\/p>\n This standard applies to the following fuels:<\/p>\n Category D gaseous fuel: natural gas; see ISO 13623;<\/p>\n<\/li>\n Category E gaseous fuel: LPG vapour, and natural gas or LPG vapour; see ISO 13623.<\/p>\n<\/li>\n<\/ul>\n List of the reference product standards <\/td>\n<\/tr>\n Test for delamination and strength of the joint line <\/td>\n<\/tr>\n Resistance to gas constituents <\/td>\n<\/tr>\n Thermal durability of the outer layer of M-pipes <\/td>\n<\/tr>\n Adhesion test <\/td>\n<\/tr>\n Odour permeability <\/td>\n<\/tr>\n Resistance to tensile load on joints <\/td>\n<\/tr>\n Crush test on joints <\/td>\n<\/tr>\n Impact resistance test on joints <\/td>\n<\/tr>\n Thermal cycling test on joints <\/td>\n<\/tr>\n Repeated bending test <\/td>\n<\/tr>\n Plastics piping systems.
