20、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
21、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, Par
22、t 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 the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of th
23、is 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 9046 was prepared by Technical Committee ISO/TC 59, Building construction, Subcommittee SC 8, Jointing products.This second editio

Other substrate materials may be used as agreed by the par
30、ties concerned.For each test specimen, two substrate pieces of the same material are required with dimensions as shown inFigures 1 and 2. Test substrates of other dimensions may be used, but the dimensions of the sealant bead and thearea of adhesion shall be the same as those shown in Figures 1 and
