GB/T 18443.6-2010 Testing method of performance for vacuum insulation cryogenic equipment—Part 6:Heat-leak rate measurement
Basic Information
Scope
This part of GB/T 18443 specifies the test principles and methods for measuring the heat leakage of vacuum-insulated cryogenic equipment, as well as requirements for test devices, equipment and instruments, test conditions and preparation, test procedures, data processing, test records, and test reports.
This part is applicable to the measurement of heat leakage in vacuum-insulated cryogenic pressure vessels, vacuum-insulated cryogenic welded gas cylinders, vacuum-insulated pipes and their fittings, and other vacuum-insulated cryogenic equipment, except for those used for the storage and transportation of liquid hydrogen. Other equipment can be implemented according to this standard.
The flow meter measurement method is suitable for measuring the heat leakage of vacuum-insulated cryogenic pressure vessels and vacuum-insulated cryogenic welded gas cylinders, while the surface temperature measurement method is suitable for measuring the heat leakage of vacuum-insulated pipes and their fittings.
