This part of IEC 60512, when required by the detail specification, is used for testing electomechanical components within the scope of technical committee 48. It may also be used for similar devices when specified in a detail specification. The object of this part of IEC 60512 is to detail a standard test method to measure the deflection of a simulated contact in its cavity or housing. Although this test method is intended for cylindrical male contacts, and is particularly applicable to those where the contacts fit into an insert, which may have some elasticity, its use for contacts with other geometries and housing details, is not excluded. In which case, the detail specification should contain sufficient detail, given under Clause 5, to enable the test to be done.
