BS EN IEC 61123:2020

This standard BS EN IEC 61123:2020 Reliability testing. Compliance test plans for success ratio is classified in these ICS categories:

• 03.120.01 Quality in general
• 03.120.30 Application of statistical methods
• 21.020 Characteristics and design of machines, apparatus, equipment

IEC 61123:2019 is intended to define a procedure to verify if a reliability of an item/system complies with the stated requirements. The requirement is assumed to be specified as the percentage of success (success ratio) or the percentage of failures (failure ratio). This document can be used where a number of items are tested (number of trials performed) and classified as passed or failed. It can also be used where one or a number of items are tested repeatedly. The procedures are based on the assumption that the probability of success or failure is the same from trial to trial (statistically independent events). Plans for fixed trial/failure terminated tests as well as truncated sequential probability ratio tests (SPRTs) are included. This document contains extensive tables with ready-to-use SPRT plans and their characteristics for equal and non-equal risks for supplier and customer. In the case of the reliability compliance tests for constant failure rate/intensity, IEC 61124 applies. This second edition cancels and replaces the first edition published in 1991. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
The sequential probability ratio test (SPRT) [1, 2][1] has been significantly developed in recent years [3, 4, 5]. This edition contains shorter and accurate tests, a wide range of test plans, and significant additional characteristic data, as follows:
the tests are significantly truncated (the maximum trial numbers are low) without substantially increasing the expected number of trials to decision (ENT);
the true producer’s and consumer’s risks (?', ?') are given and very close to the nominal (?, ?);
the range of the test parameters is wide (failure ratio, risks and discrimination ratio);
the test plans include various risk ratios (not restricted to equal risks only);
the values of ENT are accurate and given in the relevant region (for practical use);
guidelines for extension of the test sets (interpolation and extrapolation) are included.
In Annex C, the use of the cumulative binomial distribution function of Excel that simplifies the procedure of designing has been added (Clause C.3).
