A-A-50682

c. Altitude Requirements. The equipment shall meet its required performance and accuracy requirements under the altitude requirements for class 5 equipment as specified by MIL-T-28800.

d. Vibration Requirements. The equipment shall meet the class 5 Vibration Requirements as specified by MIL-T-28800.

e. Mechanical Shock Requirements.

(1) Shock, Functional. The equipment shall meet the class 5 shock, pulse requirement as specified by MIL-T-28800.

(2 ) Transit Drop. The equipment shall meet transit drop requirement as specified by

MIL-T-28800.

(3) Bench Handling. The equipment shall meet the requirements as specified by MIL-T-28800.

(4) Shock, High Impact. The equipment shall meet the requirements as specified by

MIL-T-28800.

f. Electromagnetic Interference. The equipment shall comply with MIL-T-28800, Table XII.

g. Magnetic Environment. The equipment shall comply with the magnetic environment requirements of MIL-T-28800.

9. Reliability. Reliability verification testing, shall be in accordance with the type III, class 5 environmental conditions of MIL-T-28800.

a. Mean Time Between Failures (MTBF). The equipment Mean Time Between Failures (MTBF)

shall be 2,000 hours.

b. Pre-Conditioning Requirement. Each deliverable equipment shall be capable of being subjected to the environmental screening effects of burn in and thermal cycling, with thermal cycling being accomplished in the sample testing phase.

(1) Burn-In. Burn-in shall expose the equipment to extended periods of elevated temperatures, (40'C for a minimum of 100 hours). Each equipment which fails during burn-in shall be repaired and fully retested, until failure free. Failures which occur during the burn-in test shall be noted and reported but shall not count toward the establishment of MTBF. Prior to and following

burn-in, a Satisfactory Operation Test (SOT) shall be performed. A Satisfactory Operation Check

(SOC) shall be performed conducted at selected times during the burn-in test.

(2) Thermal Cycling. Thermal Cycling shall expose the equipment to hot and cold cycle for Class

5 equipment per MIL-T-28800. Each equipment which fails during thermal cycling shall be repaired and full cycling test shall be noted and reported but shall not count toward the cycling, a
