13、s). 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 represented on that committee. International organizations, governmental and n
14、on-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 drafted in accordance with the rules given in the ISO/IEC Directives, Pa
15、rt 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 International Standard requires approval by at least 75 % of the member bodies castin
16、g 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 13477 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valv

19、 1 Thermoplastics pipes for the conveyance of fluids Determination of resistance to rapid crack propagation (RCP) Small-scale steady-state test (S4 test) 1 Scope This International Standard specifies a small-scale (S4) test method for determining the arrest or propagation of a crack initiated in a t
20、hermoplastics pipe at a specified temperature and internal pressure. This International Standard is applicable to the assessment of the performance of thermoplastics pipes intended for the supply of gases or liquids. In the latter case, air can also be present in the pipe. NOTE This test method was
21、developed using monolayer thermoplastics pipes. Its applicability to multi-layer/coated pipes has yet to be fully confirmed and is under study. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cit
22、ed applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
