Geometrical product specifications (GPS) - Inspection by measurement of workpieces and measuring equipment - Part 1 : Decision rules for verifying conformity or nonconformity with specifications

ISO 14253-1:2017 establishes the rules for verifying the conformity or nonconformity with a given tolerance for a characteristic of a workpiece (or a population of workpieces) or with a given maximum permissible errors for a metrological characteristic of a measuring equipment, including when the measured value falls close to the specification limits, taking measurement uncertainty into account.ISO 14253-1:2017 applies to specifications defined in general GPS standards (see ISO 14638), i.e. standards prepared by ISO/TC 213, including:- workpiece specifications and population specifications (usually given as an upper specification limit or a lower specification limit or both);- measuring equipment specifications (usually given as maximum permissible errors).ISO 14253-1:2017 only applies for characteristics and maximum permissible errors expressed as quantity values.

Geometrical product specifications (GPS) - Inspection by measurement of workpieces and measuring equipment - Part 1 : Decision rules for verifying conformity or nonconformity with specifications

ISO 14253-1:2017 establishes the rules for verifying the conformity or nonconformity with a given tolerance for a characteristic of a workpiece (or a population of workpieces) or with a given maximum permissible errors for a metrological characteristic of a measuring equipment, including when the measured value falls close to the specification limits, taking measurement uncertainty into account.

ISO 14253-1:2017 applies to specifications defined in general GPS standards (see ISO 14638), i.e. standards prepared by ISO/TC 213, including:

- workpiece specifications and population specifications (usually given as an upper specification limit or a lower specification limit or both);

- measuring equipment specifications (usually given as maximum permissible errors).

ISO 14253-1:2017 only applies for characteristics and maximum permissible errors expressed as quantity values.

Geometrical Product Specifications (GPS) - Inspection by measurement of workpieces and measuring equipment - Part 1 : decision rules for proving conformity or nonconformity with specifications

ISO 14253-1:2013 establishes the rules for determining the conformity or nonconformity with a given tolerance for a characteristic of a workpiece (or a population of workpieces) or limits of maximum permissible errors for a metrological characteristic of a measuring equipment, taking into account the measurement uncertainty. These rules are different for tolerances to individual workpieces and tolerances to workpiece populations. It also gives rules on how to deal with cases where a clear decision (conformity or nonconformity with specification) cannot be taken, i.e. when the measurement result falls within the uncertainty range that exists around the specification limits. ISO 14253-1:2013 applies to specifications defined in general GPS standards (see ISO/TR 14538), i.e. standards prepared by ISO/TC 213, including: ? workpiece/population of workpieces specifications (usually given as an upper tolerance limit or a lower tolerance limit or both), and; ? measuring equipment specifications (usually given as maximum permissible errors). ISO 14253-1:2013 only applies for characteristics expressed as numerical quantity values.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
