| Abstract: |
| This paper introduced the historical origination and iterative development processes of natural environment tests, laboratory environment tests, and the equipment environmental engineering which represented by a series standards of MIL-STD-810. It emphatically introduced the evolutionary process of equipment environmental engineering according to the time line:firstly, a set of preliminary test procedures grew into more standardized test methods (MIL-STD-810A), then gradually transformed into guiding documents (MIL-STD-810D) to help users with execution manner, and finally developed into a systematic management document (MIL-STD-810F). On the other hand, their necessity and historical limitations were also reviewed from a dynamic perspective. For the newly formed standard MIL-STD-810H, this paper made a detailed introduction about its content, application purpose, user community, environmental factor category, and application guidelines. The discussion revealed that the equipment environmental engineering is a systematic engineering, and it is necessary to carry out environmental engineering management by incorporating related works into the whole process of equipment acquisition to release its potential effectiveness. This paper compared domestic standards GJB 150, GJB 4239 and the series standards of MIL-STD-810 in terms of their relationship, similarity and application difference after localization. Results detected that the top-level design standards such as GJB 4239 required more supporting standards for future development. Moreover, the discussion indicated that the equipment environmental engineering is not only about the environmental test, and the environmental test is not only about checking of evaluation methods. Natural environmental testing cannot be replaced by laboratory environmental testing. The equipment should be subject to the real climate and slow accumulation effect of environments if conditions were permitted. And the environmental testing should pay more attention to the recurrence of environmental effects rather than reproducing the environment conditions. Meanwhile, the environmental experiments should be tailored and designed according to the environmental conditions to which each particular equipment would be exposed during their whole lifetime, rather than simply executing the instruction according to the well-regulated environmental testing menu. |
