DTIC ADA392261: Climatic Extremes for Military Equipment

Environmental conditions whose extremes may damage military equipment, or render it inoperative, are defined under seven stresses: thermal, humidity, precipitation, wind, penetration and abrasion, salt spray, and atmospheric pressure. For each of these seven stresses, the probable and practical extremes have been determined from thorough analyses of available information. Conditions are proposed (summarized in tabular form at the end of the report) for the design and evaluation of military equipment intended for use under such extremes Operation is characterized under the headings of Ground and Ship-board, with the first being subdivided into World-wide, Arctic Winter, Hot Desert, and Moist Tropics Applicability of the proposed conditions to each of these types of intended use is indicated. World-wide storage conditions are considered separately. The conditions as described are intended as a basis for developing laboratory tests to be used in routine evaluation of items, and also for design criteria. Final testing, to validate the design and laboratory tests, should be done at special test sites in areas where the probable extremes are most likely to be approached.
