This part of IEC 60695 specifies the mould stress relief distortion test as a test method for use by product committes. It is applicable to electrotechnical equipment including parts made from polymeric materials. This test is intended to simulate the effects caused by the relieving of moulding stresses by conditioning the product or part at a temperature higher than the maximum normal operating temperature and observing the nature of the resulting changes. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparations of its publications.
