MIL-T-740G
4.3.2.1.1 Reliability verification. To determine conformance to 3.1.1, the Minimum Acceptable Value (MAV) of 545 MMBF shall be demonstrated during initial production testing (see 4.3.2.1). The reliability requirement shall be verified at a point estimate. The point estimate is computed by dividing the total cumulative test miles (of designated test vehicles) by the total number of associated mission failures.
4.3.2.1.2 Maintainability verification. To determine conformance to 3.1.2, the maintainability requirements will be verified during initial production vehicle test (see 4.3.2.1).
4.3.2.1.3 Durability verification. To determine conformance to 3.1.3, the durability requirements shall be verified during initial production testing, (see 4.3.2.1), at 50% confidence (Binominal Distribution).
4.3.2.2 Test failure. Failure of the vehicle to comply with any of the requirements specified or any deficiency of a workmanship or materials nature found on the vehicle during or as a result of the 20,000 mile or 11,400 mile test, will be cause for rejection of the vehicle. Further, the Government will refuse to continue acceptance of production vehicles until evidence has been provided by the manufacturer that corrective action has been taken to eliminate the deficiency found during or as a result of the 20,000 mile or 11,400 mile test shall be prima facie evidence that all vehicles already accepted prior to completion of the 20,000 or 11,400 mile tests are similarly deficient, unless evidence satisfactory to the contracting officer is furnished by the contractor that they are not similarly deficient. Such deficiencies on all vehicles shal1 be corrected by the contractor without cost to the Government.
