DIN EN ISO 14253-1:2013-12

This part of ISO 14253 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 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 the procedure for dealing with those cases where a clear decision (conformity or nonconformity with specification) cannot be taken, that is, when the measurement result falls within the uncertainty range (see 3.23) that exists around the specification limits. This part of ISO 14253 applies to specifications defined in general GPS standards (see ISO/TR 14638), for example 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). This part of ISO 14253 only applies for characteristics expressed as numerical quantity values. This document (FprEN ISO 14253-1:2013) has been prepared by Technical Committee ISO/TC 213 "Dimensional and geometrical product specifications and verification" in collaboration with Technical Committee CEN/TC 290 "Dimensional and geometrical product specification and verification", the secretariat of which is held by AFNOR (France). On the national level Working Committee NA 152-03-02 AA "CEN/ISO Geometrische Produktspezifikation und -prüfung" ("CEN/ISO Geometrical product specification and verification") at the Fundamental Technical Standards Committee (NATG) at DIN is responsible.
