The issue of low-temperature shock
Thread Content
This post was last edited by X6TT on 2023-4-11 08:22. As the title suggests, if PQR tests have already been conducted at the relevant temperatures, is it still necessary to carry out low-temperature impact tests on each individual unit of the product during actual production?
According to ASME standard requirements, the low-temperature impact test is conducted on each batch of products, rather than only for the PQR. Therefore, even if the PQR test at that temperature has been completed, each product still needs to undergo low-temperature shock testing to ensure quality and safety performance. At the same time, the testing temperature and conditions also need to be determined based on the usage conditions and requirements of the specific product. .
Hello, which specific requirement of the ASME standard are you referring to? Could you list them?
MDMT is -170°C, and the material is A182 F316
