MIL-STD-690D, DEPARTMENT OF DEFENSE STANDARD PRACTICE: FAILURE RATE SAMPLING PLANS AND PROCEDURES (10 JUN 2005)., This standard provides procedures for failure rate (FR) qualification, sampling plans for establishing FR levels at selected confidence levels, and lot conformance inspection procedures associated with FR testing for the purpose of direct reference in appropriate military electronic parts established reliability (ER) specifications. Figures and tables throughout this standard are based on exponential distribution. Weibull distribution will be acceptable in certain components such as capacitors. Use of Weibull distribution for any component must be approved by the qualifying activity. This standard also provides guidance to specification writers in the use of this standard (see appendix A) and references material for users of ER parts.
