1 Scope This part of GB/T 18443 specifies the basic requirements for test environment, test equipment, measured piece and test medium, test items and sequence, data processing, test record and test report in test for performance of vacuum insulated cryogenic equipment. This part is applicable to the test for performance of vacuum insulated cryogenic equipment not used to store and transport liquid hydrogen medium; other equipment may also refer to the provisions of this part. 2 Normative References The following normative documents contain provisions which, through reference in this part of GB/T 18443, constitute provisions of this part. For dated references, subsequent amendments to (excluding amending errors in the text), or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this standard are encouraged to study whether the latest edition of the normative document is applicable. For undated references, the latest edition of the normative document applies.
