By studying the assessment requirements of environmental test method standards such as GB/T 2423,GJB 150A and RTCA DO-160G on measurement uncertainty,and combining the existing standards and cases of environmental test uncertainty assessment,three kinds of uncertainty evaluation situations involved in environmental test are summarized,namely:uncertainty evaluation of environmental test measurement system,uncertainty evaluation of environmental test condition parameters and uncertainty evaluation of environmental test results. The evaluation of uncertainty in the above three kinds of environmental tests is described and analyzed one by one,and the evaluation ideas and cases are provided,which can provide guidance for testing institutions to evaluate the uncertainty of environmental tests effectively and make reasonable use of the uncertainty results.
