The U.S. Department of Defense (DoD) recently issued Change Notice 1 to MIL-STD-810G, Environmental Engineering Considerations and Laboratory Tests.  This change notice incorporates more changes – climatic and dynamic – than any previous revision of -810.

A PDF of Notice 1 is available here.  It’s a bulging 1,058 pages, over 280 pages more than the Revision G alone and more than twice as many pages as Revision F.  Changes are marked by lines in the margins.   

Major changes include:

• In Part 1, a significantly expanded section on the Life Cycle Environmental Profile (LCEP)
• In Part 2, all test methods – 500 through 528 – have been updated with a new note
• Only Method 528 can be called out in blanket fashion now
• A rewrite of mechanical shock
• Additional guidance in combining procedures

MIL-STD-810 is used by both the U.S. military and industry to assure that the environmental design and test limits of equipment match the requirements that equipment will face in actual use.

Whether a military product must be tested to Change Notice 1 is dependent on the DoD contract.  The DoD uses the product’s life cycle environmental profile and its anticipated deployment region to determine which standard version to specify.
