ISO 15530-3:2011 specifies the evaluation of measurement uncertainty for results of measurements obtained by a CMM (coordinate measuring machine) and by using calibrated workpieces or measurement standards. It provides an experimental technique for simplifying the uncertainty evaluation of CMM measurements, whose approach (substitution measurements) leads to measurements being carried out in the same way as actual measurements, but with calibrated workpieces of similar dimension and geometry instead of the unknown workpieces to be measured. Non-substitution measurements on CMMs are also covered, as are the requirements of the uncertainty evaluation procedure, the measurement equipment needed, and the reverification and interim check of the measurement uncertainty.
Abstract
Overview
ISO 15530-3:2011 - Geometrical product specifications (GPS) - Coordinate measuring machines (CMM): Technique for determining the uncertainty of measurement - Part 3 - defines an experimental method to evaluate the measurement uncertainty of CMM results by using calibrated workpieces or measurement standards. The standard describes a substitution-style approach where calibrated artefacts of similar geometry and dimension are measured under the same conditions as production parts to derive realistic, task‑specific uncertainty estimates.
Key topics and requirements
- Scope: Applies to both substitution measurements (using a check standard to correct systematic CMM errors) and non‑substitution measurements (using the raw CMM indication).
- Similarity conditions: Calibrated workpiece must be similar to the production part in dimension, geometry, material and measuring strategy. Examples:
- Dimensions: within 10% for features > 250 mm; within 25 mm for features
