International organizations, governmental and non-governmental, in liaison with isO, also take part in the work. IsO collaborates closely with the InternationalElectrotechnicalCommission(lEC)onallmattersofelectrotechnicalstandardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 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 casting a vote.

ISO 1798 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 4, Products (other than hoses). This fourth edition cancels and replaces the third edition (isO 1798:1997), which has been technically revised It also incorporates the Technical Corrigendum ISO 1798:1997/Cor.1:2003. The main change is the introduction of a second type of test piece (see Figure 1) and a comparison of the results obtained with the two test pieces (see Annex A) @ ISO 2008 - All rights reserved ional Organization for Standardizatior INTERNATIONALSTANDARD ISO 1798:2008(E) Flexible cellular polymeric materials Determination of tensile strength and elongation at break WARNING - Persons using this International Standard should be familiar with normal lab
