- Scope
- This standard specifies the test principles, general requirements, test equipment, sample preparation, test procedures, data processing and test reports for adsorbent low-temperature and low-pressure adsorption performance tests. This standard is applicable to the adsorption performance test of activated carbon and molecular sieve adsorbents used in vacuum-insulated cryogenic vessels, cryogenic devices, cryogenic transportation pipelines and cryogenic valves at low temperature (less than 120K) and low pressure (10Pa~10Pa). The adsorption performance test of other adsorbents can be performed as a reference.
