11、22:2007(E) iv ISO 2007 All rights reserved Foreword ISO (the International Organization for Standardization) 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
12、 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, also take part in the work. ISO collaborates closely with the International Elect
13、rotechnical 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 committees is to prepare International Standards. Draft International Standards adopte
14、d 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. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
15、 rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10722 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 189, Geosynthetics, in collaboration with Technical Committee ISO/TC 221, Geosynthetics, in accordance with
16、the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). This first edition of ISO 10722 cancels and replaces ISO/TR 10722-1:1998.

18、by granular material 1 Scope This International Standard describes an index test procedure for simulating mechanical damage to geosynthetics, caused by granular material, under repeated loading. The damage is assessed visually and by the loss of tensile strength. Other reference tests may be used to
19、 assess the damage caused by this test. The test method described is an index test procedure, using a standard granular material. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated referenced, only the edition cited applies. Fo

22、damaged in this procedure 4 Principle A geosynthetic specimen is placed between two layers of a synthetic aggregate and subjected to a period of dynamic loading. The geosynthetic specimen is then removed from the test apparatus, examined for any visual damage and then subjected to a mechanical or hy
23、draulic test, to measure the change in mechanical or hydraulic properties. The result is expressed as the change (in percent) of the reference property. The visual damage is also reported.
