9、e 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 represented on that
10、 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 drafted in ac
11、cordance with the rules given in the ISO/IEC Directives, Part 3. 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 member bodies casting a vote. Attention is
12、 drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 13431 was prepared by the European Committee for Standardization (CEN) i
13、n collaboration with ISO Technical Committee TC 38,Textiles, Subcommittee SC 21,Geotextiles, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). Throughout the text of this standard, read “.this European Standard.“ to mean “.this International Standard.“

Application of this standard is lim
20、ited to those products and applications where the risk of collapse of a structure due to premature failure or to strain/time variation of the reinforcement under constant load is of essential importance. As the test is carried out over a long period of time and the procedure is complex, it is theref
21、ore recommended that the test is not considered to be a routine quality control test. The results of the test may not be representative of the performance of the products when subject to soil pressures. 2Normative References This European Standard incorporates by dated or undated reference, provisio
22、ns from other publications. These normative references are cited at the appropriate points in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by a
23、mendment or revision. For undated references, the latest edition of the publication referred to applies.
