The work of

19、 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 non-governmental

20、, 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, Part 3. Draft Int

21、ernational 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 Internatio

22、nal 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 14589 was prepared by Technical Committee ISO/TC 2, Fasteners. Annex A of this International Standard is for information only. ENISO14589:2000

23、INTENRATIONAL TSANDADR ISO 98541:(0002)E1 Blind rivets Mechanical testing 1 Scope This International Standard specifies the methods of mechanical testing of blind rivets including: shear test (see clause 3), tensile test (see clause 3), mandrel head retention capability test (see clause 4), mandrel

24、push out resistance test (prior to setting) (see clause 5), and mandrel break load test (see clause 6), at an ambient temperature of 10 Ct o3 5C. It applies to blind rivets with nominal diameters up to and including 6,4 mm. 2 Normative reference The following normative document contains provisions w

25、hich, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the p

26、ossibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies.

28、by a shear load or tensile load to failure. 3.2 Test fixtures for shear and tensile tests Two test fixtures are specified for each of both test methods. The test fixtures specified in 3.2.1.1 and 3.2.2.1 may be used for routine testing. The test fixtures specified in 3.2.1.2 and 3.2.2.2 may also be

29、used for routine testing but are decisive in the case of dispute and are the referee test fixtures in such cases. 3.2.1 Test fixtures for shear testing 3.2.1.1 Routine shear testing See Figure 1 for basic dimensions.

The maximum load is recorded as the ultimate shear or tensile load of the rivet. If the rivet fails before the specified minimum shear or tensile load is reached, the rivet has not passed the test. 3.4 Testing of short ri
