Sampling Plans for Durability Testing Beyond Requirements

Abstract

The Test and Evaluation Command funded the Experimental Design and Analysis Branch, SECAD, BRL to develop procedures for planning durability tests which allow testing an item beyond its required durability mission time so that statistical inferences concerning durability can be made with higher confidence. This report gives recommended procedures to accomplish this goal, summarizes the assumptions underlying these procedures, outlines the theory required for their development and gives tables and sampling plans which are needed to implement them. A durability test is conducted to collect data which is used to draw interferences concerning the probability that a unit which is to be evaluated will be able to operate for a minimum specified time, number of cycles, etc. without failure due to wearout. Keywords: Durability; Reliability; IFR; IFRA; Design of experiments; Moderately distribution free; Exponential distribution; Confidence limits; Distribution free.
