This military standamf is approved for use by all Departments and Agencies of the Departmnt of Wfense. ”

Beneficial cozummts (recommmdations, additions, deletions) and any pertinent da-which may be of use in inqmcwing this docum nt should be addressed to: AsD/w, IAFight-Patterson MB OH 45433-6503 by using the se1f-addressed Standardization Domxmnt Iuprov-nt Propotial (DD Form 1426) appearing at the end of this docuumt by letter.

IuUL-STD-81OE has been revised to require careful attention to environnmnts throughout the deve 1opeumt process. A course of action for determining and assessing the enviro~ts to &i& an item WI 11 be exposed during its service 1ife has been added to section 4, General Requirements. The additional General w==mts aid in preparation for design and preparation for teBt.

Doaxmmtation requirements for the design M testing process have alsa been added to section 4.

The bulk of the standard remains devoted to te$t nmthods. Individual -thods have been rev ised to encourage accurate determination of the env iromntal Stresses that an equipmmt wi 11 enmxmter during Its service 1ife. Guidance for accelerated or aggravated testing during the design process is incluled in SO- cases. Each test mthod has ?xwn divided into tm sections: S&tion I provides guidance for choosing and tailoring a particular test procedure. Section II inclties step-by-step test procedur-fw. In somw -thods, not only the test values, but also the seqwnce of steps is hi lorable.

The re-lt of this revision wil 1 be that this standard cannot be called out or applied as a fixed, relatively siqle mutme. Instead, an environmnkl engineering specialist wil 1 have b choose and ●lter the -t ~ures to suit a particular combination or seqmnce of envimmxumtal conditions fop a specific equipa9nt application.

The mthods of this standard are not intended to aatiafy al 1 safety cowl iance testing mquirermnts.

10 ThiS d~nt con~in$ 6 sections. Sections 1 through 3 con-in general information.

Section 4 con-ins trothtailoring guides and general teat infor!mtion that relate to the teat umthods of section 5. Section 5 contains climatic and dynamic test =thods, and section 6 has references to contractual requirements.

2. The Procuring Activity/Developer nust determine the magnituie of the tailoring effort appropriate for the program in question. Tailoring can provide long range ‘ coat savings in that materiel will be designed and developed to survive its anticipated deploy=nt scenario.

3. Paragraph 4.2 explains the tailoring process and the steps involved (see figure 1, H!OWTO Use MIL-=81OE). Paragraph 4.3 explains the use of msasured data, and paragraph 6.2 details the contractual requirements in the form of Data Item Descriptions (DID’s).

4. Each test -thod of Section 5 is divided into 2 parta: Section I containa backgroundo~ the enclosed procedures and rationale (where possible) for the test parameters. Section II containg the step-by-step test procedures which require paramter levels that are to be developed by the environ!m!ntal analyses.

5. Secti~ 5 of this domm= nt also contains ‘fallback= paramter levels ~ich can be applied in @action II of each nmthod if better information is not available.

6. The test nwthods of section 5 address various cli-tic and dynamic envirorumntdsituations. The user of MIL-Si’D-810E must determine Xicli wthods are appropriate for the specified program and *ich test procedures within the test method are appropriate.

7. Regardless of *ich approach is chosen, at the end of Section I of each test nmthod, a list of infor!mtion iS specified that is required in order to condwt the test procedures of Section II of that method. This information wt be assenbled by the envimnmmtil specialist end provided to the equipment supplier.
