It also incorporates ISO 17484-1:2006/Cor.1:2008.ISO 17484 consists of the following parts, under the general title Plastics piping systems Multilayer pipe

22、 systems for indoor gas installations with a maximum operating pressure up to and including 5 bar (500 kPa): Part 1: Specifications for systems Part 2: Code of practice ISO 2014 All rights reserved vBS ISO 17484-1:2014ISO 17484-1:2014(E)IntroductionThis part of ISO 17484 was developed in response to

23、 worldwide demand for minimum specification for multi-layered pipes for indoor gas applications.Multi-layered pipes are delivered generally as a complete system. Pipes, fittings, tools, etc., are not compatible with components of another brand, generally. An advantage is that all components are perf

24、ectly geared to one another, but for repair, the lack of compatibility might be problematic in the future.Safety of systemsDepending on the construction of the house, pipework layout and other local circumstances, it is possible that additional safety devices are required to fulfil the demands of fi

25、re safety. Safety aspects of the system are described in ISO 17484-2 and national regulations shall be taken into account.Code of practiceThe second part of ISO 17484 is the code of practice for installation.Recommendations on design, construction and protection in case of fire of the gas indoor ins

26、tallation are given in EN 1775.References to ISO/TC 138/SC5 workTest methods referred to in this part of ISO 17484 have been developed by SC 5 as far as possible. However, not all test methods needed are in the working programme of SC 5. These test methods are placed in Annexes B to K of this part o

27、f ISO 17484. It is planned that these tests will be developed as International Standards in the future.For multilayer pipe construction, consisting of a layer of a reference standard material, an adhesive and a non-stress-designed layer, procedure I and the relevant product standards are followed fo

28、r all aspects, excluding the aspects of delamination and, if applicable, oxygen permeation.For example, layers can have the following purposes: ability to withstand the pressure; ability to realize interlayer adhesion; ability to block or greatly diminish incoming UV and/or sunlight; ability to mech

29、anically protect the outside layer; ability to control the longitudinal expansion; ability to give the multilayer pipe a colour (inside layer or outside layer).Some characteristics can be combined in one layer.vi ISO 2014 All rights reservedBS ISO 17484-1:2014Plastics piping systems Multilayer pipe

30、systems for indoor gas installations with a maximum operating pressure up to and including 5 bar (500 kPa) Part 1: Specifications for systems1 ScopeThis part of ISO 17484 specifies the general requirements and the performance requirements for multilayer pipe systems based on pipes, fittings and thei

31、r 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 based on

32、 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 out

33、er 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.).NOTE The maximum operation pressure of PE 80 may be lower than 5 bar.This part of ISO 17484 applies to systems that operate at temperatu

34、res of 20 C up to +60 C.For the purpose of this part of ISO 17484, 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.This part of ISO 17484 is applicable for piping

35、 systems used in buildings to supply gas with a maximum operating pressure up to and including 500 kPa (5 bar)1).This standard applies to the following fuels: Category D gaseous fuel: natural gas; see ISO 13623; Category E gaseous fuel: LPG vapour, and natural gas or LPG vapour; see ISO 13623.2 Norm
