33、 is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be repre
34、sented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are
35、 drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internationa
36、l Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 17484-1 was pr
37、epared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 4, Plastics pipes and fittings for the supply of gaseous fuels. ISO 17484 consists of the following parts, under the general title Plastics piping systems Multilayer pipe system
38、s for indoor gas installations with a maximum operating pressure up to and including 5 bar (500 kPa): Part 1: Specifications for systems A Part 2 dealing with the code of practice is planned.

39、s of the SABS .ISO 17484-1:2006(E) vi ISO 2006 All rights reservedIntroduction This part of ISO 17484 was developed in response to worldwide demand for minimum specification for multi-layered pipes for indoor gas applications. Multi-layered pipes are delivered generally as a complete system. Pipes,
40、fittings, tools, etc., are not compatible with components of another brand, generally. An advantage is that all components are perfectly geared to one another, but for repairing, the lack of compatibility might be problematic in the future. Fire safety of systems Depending on the construction of the
41、 house, pipework layout and other local circumstances, it is possible that additional safety devices are required to fulfill the demands of fire safety. Safety aspects of the system will be described in the planned Part 2. Code of practice The planned second part of ISO 17484 will be the code of pra
42、ctice for installation. Recommendations on design, construction and protection in case of fire of the gas indoor installation are given in EN 1775). References to ISO/TC 138/SC5 work Test methods referred to in this part of ISO 17484 have been developed by SC 5 as far as possible. However, not all t
43、est methods needed are in the working programme of SC 5. These test methods are placed in Annexes B to K of this part of 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 standa
44、rd material, an adhesive and a non-stress-designed layer, procedure I and the relevant product standards are followed for 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;
45、ability to realize interlayer adhesion; ability to block or greatly diminish incoming UV and/or sunlight; ability to mechanically protect the outside layer; ability to control the longitudinal expansion; ability to give the multilayer pipe a colour (inside layer or outside layer). Some characteristi
46、cs can be combined in one layer.

47、tions with a maximum operating pressure up to and including 5 bar (500 kPa) Part 1: Specifications for systems 1 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
48、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 thermoplastics, for which
49、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 c
