What is BS EN 60695-10-3 ‒ Mould stress relief distortion test about ?
BS EN 60695-10-3 is a part of an international multi-series standard that covers safety guidelines for fire hazard testing.
BS EN 60695-10-3 specifies a mould stress relief distortion test. It is applicable to electrotechnical equipment including parts made from polymeric materials.
BS EN 60695-10-3 gives a test method that is intended to evaluate the effects caused by relief of the residual process-induced stress, set in a moulded polymeric assembly of an end product. This stress relief occurs when the sample (energized or not), is exposed to conditioning at a defined temperature for a defined period of time. The test specimen is considered to have satisfactorily withstood the test if, after conditioning to room temperature, it meets defined test criteria.
BS EN 60695-10-3 is a basic safety publication that is intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51.
Who is BS EN 60695-10-3 ‒ Mould stress relief distortion test for ?
BS EN 60695-10-3 on mould stress relief distortion test is useful for:
- Firefighting companies
- Firefighting colleges
- Test /service providers for fire hazard testing
- Technical committees for fire hazard testing
Why should you use BS EN 60695-10-3 ‒ Mould stress relief distortion test ?
Fires start with ignition and can grow, leading in some cases to flash-over and a fully developed fire. The risk of abnormal heat and the potential hazards associated with abnormal heat, need to be considered while designing any electrotechnical product.
BS EN 60695-10-3 describes a test method called mould stress relief distortion test, that simulates the effects caused by relief of the residual process-induced stress, frozen in a moulded polymeric assembly of an end product, when exposed to conditioning at the maximum allowable operating temperature. It gives a test method to evaluate if the product after conditioning continues to meet the requirements of the relevant product specification or not.
BS EN 60695-10-3 basically provides you with the guidance to prevent ignition caused by an electrically energized component part, and to confine any resulting fire within the bounds of the enclosure of the electrotechnical product in the event of ignition.
