Scope

This document specifies a mould stress relief distortion test.
This document applies to electrotechnical equipment containing parts made of
polymeric materials.
This test method is mainly used to evaluate the effect caused by the residual process
stress relief of finished moulded polymer components. Stress relief occurs when the
sample (energized or not) is exposed to a specified temperature for a certain period of
time. If the sample meets the specified test standard after conditioning at room
temperature, it is considered to have passed the test.
This document is intended for use by technical committees when preparing standards
in accordance with the principles set out in IEC Guide 104 and ISO/IEC Guide 51.
One of the tasks of technical committees is to use this series of standards wherever
applicable when preparing standards in this field. Unless specifically mentioned or
listed in the relevant standards, the requirements, test methods, or test conditions of this
document will not apply.
