Scope

This Part of GB/T 18443 specifies test principles and methods, test devices, equipment
and instruments, test conditions and test preparation, test procedures, data processing
and test record and test report for the heat-leak rate measurement of vacuum insulation
cryogenic equipment.
This part applies to the heat-leak rate measurement of vacuum insulation cryogenic
pressure vessels, vacuum insulation cryogenic welded gas cylinders, vacuum insulation
pipes and their pipe fittings, except the liquid hydrogen storing and transporting
equipment. Other equipment can refer to this document for the implementation.
The flowmeter measurement method is suitable for the heat-leak rate measurement of
vacuum insulation cryogenic pressure vessels, vacuum insulation cryogenic welding
gas cylinders and other vacuum insulation cryogenic equipment. The surface
temperature measurement method is suitable for the heat-leak rate measurement of
vacuum insulation pipes and their fittings.
