The GB/T 23711.2 - 2009 standard specifies the low temperature resistance test method for fluoroplastic lining Pressure Vessel. The standard specifies the technical indicators of the equipment required for the test, such as the cryogenic box, and elaborates the test process, including how to cool the container to the specified low temperature, keep it for a long time and monitor the temperature. At the same time, pay attention to the state changes of fluoroplastic lining at low temperature. Low temperature resistance performance affects the safety and Reliability of fluoroplastic lining Pressure Vessel in cold or low temperature environments. According to this standard, it can accurately inspect the low temperature resistance of the container, ensure the product mass, and help it to be applied stably in the refrigeration, cryogenic and other low temperature operations.
