1 Scope
This standard specifies the methods of mechanical testing of blind rivets including:
——shear test (see Chapter 3);
——tensile test (see Chapter 3);
——mandrel head retention capability test (see Chapter 4);
——mandrel push out resistance test (prior to setting) (see Chapter 5);
——mandrel break load test (see Chapter 6).
The ambient temperature is 10℃ to 35℃.
It applies to blind rivets with nominal diameters up to and including 6.4mm.
2 Normative Reference

3 Shear and Tensile Tests
3.1 Principle of shear and tensile tests
The tests consist of straining a blind rivet which is set in a test fixture 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 used for routine testing but are decisive in the case of dispute and are the referee test fixtures in such cases.
