Abstract: This paper will be published in two parts. The second part is about the environmental qualification test process, and the fifteen common problems related with the test process are pointed out, including basic technical conception, test standards, the role played by the test, the test management, and so on. The background and essential points of each problem and the method to improve measurements are emphasized. In the end, eight primary factors in evaluating the validity of environmental qualification tests are summarized, and what should be done in the nearest future is also indicated, which covers standardization and review of environmental qualification test documents, including test programs, single test reports and test master reports. Thus, the laboratory environmental qualification test could be more efficient at the finalizing of military aircraft products.
