BS EN 61164:2004

This standard BS EN 61164:2004 Reliability growth. Statistical test and estimation methods is classified in these ICS categories:

• 03.120.01 Quality in general
• 03.120.30 Application of statistical methods

IEC 61164:2004 gives models and numerical methods for reliability growth assessments based on failure data, which were generated in a reliability improvement programme. These procedures deal with growth, estimation, confidence intervals for product reliability and goodness-of-fit tests. The main changes with respect to the previous edition are:
- addition of two statistical models for reliability growth planning and tracking in the product design phase;
- statistical methods for the reliability growth programme in the design phase of IEC 61014;
- addition of the discrete reliability growth model for the test phase;
- addition of the fixed number of faults model for the test phase, clarification of the symbols used for various models;
- addition of real lif examples for most of the statistical models;
- numerical correction of tables in the reliability growth test example.

This publication is to be read in conjunction with IEC 61014:2003.
