The work of preparing Internationa
8、l 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 represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO,
9、also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical commi
10、ttees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In exceptional circumstances
11、, when a technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art”, for example), it may decide by a simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely
12、 informative in nature and does not have to be reviewed until the data it provides are considered to be no longer valid or useful. 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 a
13、ny or all such patent rights. ISO/TR 18124 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 5, General properties of pipes, fittings and valves of plastic materials and their accessories Test methods and basic specificat
14、ions. ISO/TR 18124:2006(E) iv ISO 2006 All rights reservedIntroduction This Technical Report is one of several documents developed by ISO/TC 138/SC 5, following the creation of the Subcommittees Working Group WG 16 at Kyoto, Japan, in 1998, in response to worldwide demand for specifications, require
15、ments and test methods for multilayer plastics pipes. The other documents include ISO 17454 1 , ISO 17455 2and ISO 17456 3 . Initially, it was intended also to publish this Technical Report, together with ISO 17453, as International Standards. The Working Group then proposed the cancellation of both
16、 these projects, for the following reasons: because of the great variety of multilayer pipes, no identical forces for different types of multilayer M pipes can be created using the test principle; the realised force is very dependent on the tolerances of the pipe because of the great variation of to
17、lerances (even for the same product), it is extremely difficult to realise the same expansion for different types of multilayer M pipe; while the test method can very well be used as a product verification test during production, to give an indication of the quality of the multilayer M pipe product,
18、 International Standards are not intended for the setting up of such tests. ISO/TC 138/SC 5 acknowledged the difficulty of standardization in this area owing to the different thicknesses of the inside layer of various types of multilayer pipes and the fact that the test force is strongly dependent o
19、n pipe dimensions and therefore on tolerances, which also vary strongly. Nevertheless, in order not to lose the acquired information, the Subcommittee decided at its 2004 plenary meeting to combine the two committee drafts, ISO/CD 18124 and ISO/CD 17453, into a single Technical Report, ISO/TR 18124.
20、 Only multilayer pipes are dealt with in this Technical Report and for its purposes cross-linked polyethylene (PE-X) as well as adhesives are to be considered as a thermoplastics material.

21、l) pipes Test method for strength of the weld line in the metal layer and bonding between layers by use of a cone 1 Scope This Technical Report specifies a method for testing the strength of the weld line in the metal layer and the adhesion between the different layers of multilayer M pipes by the u
22、se of a cone. NOTE 1 Acceptance of any inner layer made from a specific grade of material is subject to the relevant product standard or system standard and the requirements detailed in that standard. NOTE 2 The test can be used as a product verification test during production to give an indication
23、of the quality of the multilayer M pipe product. 2 Principle A test piece of specified length, cut from a multilayer M pipe, is subjected to a radial expansion by inserting a cone to verify the strength of the weld line of the metal layer and to assess the bond between the different layers.
