This document describes examples for software validation for SPC software implementing the standards of the ISO 7870 series on control charts and the ISO 22514 series on capability and performance. In detail ISO 7870‑2, ISO 22514‑2 and ISO 22514‑8 are covered. It provides data sets and test results for testing the implementation of the evaluation methods described in these standards. This includes the detection of out of control situations as well as the calculation of sample statistics and process capability indices. The test examples cover the following situations: a) General: — different sample and subgroup sizes, accuracy of calculation for large/small numbers; b) ISO 22514 series: — calculation of sample statistics for location and dispersion; — different distribution models; c) ISO 7870‑2: — calculation of control limits; — visualization of data (histogram, control charts); — detection of out of control situations.
Abstract
Overview
ISO/TR 11462-3:2020 - "Guidelines for implementation of statistical process control (SPC) - Part 3: Reference data sets for SPC software validation" provides authoritative reference data sets and expected results to validate SPC software implementations. It targets implementations of the ISO 7870 series (control charts) and the ISO 22514 series (capability and performance), with explicit coverage of ISO 7870‑2, ISO 22514‑2 and ISO 22514‑8. The technical report supplies test examples, documented evaluation results and machine-readable data (Annex A / online) so developers and users can confirm correct calculation, visualization and out-of-control detection.
Key topics and technical requirements
- Reference data sets and documented test results covering 11 test examples that represent normal, Weibull, Rayleigh and non‑normal/time‑dependent processes (e.g., shifts, tool wear, multistate production).
- Control chart validation: calculation of control limits and centrelines according to ISO 7870‑2, using tabulated correction factors (note: using exact quantiles may change results by
