The primary emphases of MIL-STD-810E are tailoring a materiel item’s environmental design and test limits to the conditions that the specific materiel will experience throughout its service life, and establishing laboratory test methods that replicate the effects of environments on materiel, rather than trying to reproduce the environments themselves.
