scope:

This specification covers requirements for finishes necessary to protect ground electronic equipment from the deteriorating effects of climatic conditions encountered in military use. Selection of materials, processes and finishes shall be in accordance with this document and all federal, state and local environmental regulations.

When it is felt that the finish requirements of this document may compromise the performance of the equipment, the designer shall consider other possibilities, such as the use of compatible, inherently corrosion-resistant materials. For example, heat dissipation requirements of equipment may require special consideration to provide for optimum thermal conductivity. In such a case, the use of castings, welded pieces, clad metals, etc., which reduce the number of interfaces,may be satisfactory. A prudent choice of materials in the design stage will result in fewer finishing, corrosion, and environmental problems.

For application of finishes to ground electronic equipment, surfaces are classified by exposure as follows:

Type I (Exposed). Type I surfaces are areas, either exposed to view when equipment is in operating or traveling condition, or areas not exposed to view but subject to combined direct action of climatic elements. Climatic elements include temperature extremes, humidity extremes, rain, hail, snow, sleet, Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commander, US Army Laboratory Command, Attn: SLCET-RS, Fort Monmouth, NJ 07703-5000, by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.

salt-laden air, industrial atmospheres, direct solar radiation, dust, and wind blown sand. For example, the outside surfaces of any equipment are Type I areas; the inside surfaces of an open frame motor are Type I areas.

Type II (Sheltered). Type II surfaces are areas not exposed to view during equipment operation and not subject to direct action of rain, hail, snow, sleet, direct solar radiation, and sand. For example, the interior surfaces of a radio receiver or switchboard are considered Type II areas.

Any Type I finish is adequate protection for Type II exposures.
