MIL-STD-1250 Corrosion Prevention And Deterioration Control In Electronic Components And Assemblies S/S By Mil-Hdbk-1250This standard establishes minimum requirements for procedures, materials and systems for protecting electronic components in DoD systems and assemblies from adverse environments. Protective measures shall be sufficient to maintain performance characteristics within specified limits both during and after exposure to moisture, high and low temperatures, corrosive gases, chemicals and microbial fungal attack.

FOREWORD

1. This military standard is approved for use by all Departments and Agencies of the Department of Defense

2. 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 Missile Command, ATTN: AMSMI-RD-SE-TD-ST, Redstone Arsenal, AL 35898-5270 by using the Standardization Document Improvement Proposal (DD For 1426) appearing at the end of this document or by letter.

3. The purposes of this standard are to draw attention to the importance of corrosion as a major factor in the degradation of performance of electronic items; to establish minimum requirements for the control of corrosion and deterioration in DoD systems and applications; and to provide a guide to the selection of protective measures. The choice of materials and processes for electronic applications is, naturally, based on electrical properties not included in this document. It is the aim of this standard to aid in selecting from among suitable materials and processes, those which will withstand the attack of adverse environments during storage, shipment and service.

4. This standard supplements the more general requirements of MIL-STD-454, titled "Standard General Requirements for Electronic Equipment," with detailed information on the maintenance of desired characteristics during and after exposure to anticipated environments. The circuitry or design is not pertinent

to this standard except insofar as design affects susceptibility to corrosion.

5. Contractors (and subcontractors) are encouraged to present new designs, materials, and technology which will improve the items or products, but should obtain procuring activity approval prior to such use.

6. Compliance with this standard will promote reliability of electronic components and assemblies, by preventing or minimizing deterioration from environmental causes.
