Overview

EN ISO 14253-1:1998/prA1 is a draft amendment to ISO 14253-1 that clarifies decision rules for inspection by measurement under Geometrical Product Specifications (GPS). The amendment establishes how to determine conformance or non-conformance of both individual workpieces and measuring equipment while explicitly taking measurement uncertainty into account. It also addresses population specifications and differentiates rules for arithmetical and statistical tolerance definitions.

This document is developed under ISO/TC 213 in parallel with CEN/TC 290 and is intended to update the original 1998 part 1 rules with guidance on population-based specifications and the modifier [ST].

Key Topics

• Decision rules for conformance: Establishes the procedural basis for declaring a workpiece or measuring device conforming or non-conforming, considering the uncertainty range around specification limits.
• Measurement uncertainty: Requires that uncertainty associated with the measurand be evaluated and included in the decision process; the standard clarifies how indeterminate cases (measurement results within the uncertainty range) should be handled.
• Individual vs population characteristics: Explains the difference between measurands for single workpieces and those for a population; population characteristics imply different uncertainty treatment.
• Modifier [ST]: Defines the meaning of the [ST] modifier - indicating one or more population specifications linked to an individual specification. When used, conformance requires satisfying both individual and population criteria.
• Arithmetical vs statistical tolerances: Notes that decision rules differ when tolerances are defined by arithmetical calculation methods versus statistical methods.
• GPS population definition: Introduces the term GPS population as the totality of items under consideration, clarifying the scope of population-level specifications (e.g., mean, maximum, standard deviation).

Applications

This amendment is practical for quality engineers, metrologists and inspection teams who:

• Implement measurement-based inspection programs for parts and assemblies under GPS.
• Evaluate conformance of measuring equipment against maximum permissible errors.
• Apply population-level quality controls where the modifier [ST] is used in specifications.
• Need documented, consistent rules to resolve indeterminate measurement outcomes caused by uncertainty.

Benefits include improved traceability of conformance decisions, consistent treatment of population specifications, and clearer handling of uncertainty in measurement-based verification.

Related Standards

• ISO 14253-1:1998 - Base document for decision rules in GPS measurement inspection.
• ISO/TR 14638 - Guidance on specifications defined in GPS standards.
• ISO 3534-1 - Statistical vocabulary (adapted terms referenced for population definition).

For implementation, organizations should integrate the decision rules into inspection procedures, calibrations, and acceptance criteria to ensure consistent, defensible conformance decisions under GPS.
