GB/T 5169.19-2022 Translated English of Chinese Standard (GB/T 5169.19-2022, GBT5169.19-2022): Fire hazard testing for electric and electronic products -- Part 19: Abnormal heat -- Mould stress relief distortion test [Buy--download True-PDF in 3-second: https://play.google.com/books > Sign in > This BOOK > "3-dots" > Export > Save as "*.pdf"]https://www.chinesestandard.net, 25/01/2023 - 16 من الصفحات 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. |
