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. 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 4587 was prepared byTechnical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products.

NOTE1 Single-lap specimens are economical, practical and easy to make. They are the most widely used specimens for development, evaluation and comparative studies involving adhesives and bonded products, including manufacturing quality control. NOTE 2 The strength values obtained from the single-lap specimen should not be used as allowable design-stress values for structural joints. 4 Apparatus 4.1 Tensile-testing machine, selected so that the rupture of the specimen falls between 10 % and 80 % of the full-scale capacity. The response time of the machine shall be short enough so as to enable the force applied at the time of rupture to be measured accurately. The recorded force shall not differ from the true applied force by more than 1 %. The machine shall be capable of maintaining the constant speeds of testing 1)To be published. 1 lonal organizaionfcr standardzaion rights reserved Copyright Inte Not for Resale ISO4587:2003(E) used.
