ISO/TR 11462-3:2020 provides reference data sets and test results for validating software that implements statistical process control methods. It covers control charts from the ISO 7870 series and capability and performance calculations from the ISO 22514 series, including sample statistics, process capability indices, control limits, visualization, and detection of out-of-control conditions.
The report includes 11 test data sets representing normal, non-normal, Weibull, Rayleigh, time-dependent, trend, fixed-tooling, and multi-state production process conditions. Results were verified with multiple computer programs, making the data suitable for software development, implementation checks, quality assurance, and validation activities. The complete data values are provided in Annex A, with an electronic version available from the ISO standards portal.
Application Scope: SPC software development and validation, statistical quality control, process capability analysis, control chart implementation, manufacturing analytics, and conformity assessment.
