The work aims to investigate the application of environmental tests in environmental worthiness of materiel.The characteristics of different environmental tests were analyzed,the application strategy of environmental tests in different levels of materiel was examined,and the requirement of different environmental tests in life cycle of materiel was studied.It was shown that performances in authenticity,efficiency and analyzability of different environmental tests were different.At different levels of material system and in the life cycle of material,the requirements and emphases of environmental tests were different.During worthiness work of material in the new era,it is necessary to establish a strategy for comprehensive application of vari-ous environmental tests with the idea of system engineering,coordinate various environmental tests at all levels of material,and apply different environmental tests at different phases of material life cycle.In the future,the technical research and application of multi-factor environmental test and virtual environment test should be further strengthened,the basic status of natural environment test should be strengthened and the application of test in engineering should be accelerated,so as to meet the material needs of being close of actual combat,having comprehensive check,learning the real situation,conducting whole process assessment and evaluation in the new era.
