29、ards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International orga
30、nizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its
31、further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/dire
32、ctives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the

35、SO/TC 213, Dimensional and geometrical product specifications and verification, in collaboration with Technical Committee CEN/TC 290, Dimensional and geometrical product specification and verification.This third edition cancels and replaces the second edition (ISO 14253-1:2013), which has been techn
36、ically revised with the following changes: The content applies ISO/IEC Guide 98-4 and gives recommendation for simplification by using intervals representing the underlying probability. As a consequence, the default coverage factor k = 2 has been replaced with a default conformance probability of 95
37、 %. This makes the risk constant, regardless of the relationship between the specification interval and the measurement uncertainty. See Annex A for additional information. Some terminology has been updated. The explanation for the population specification modifier has been removed and can now be fo

39、O 14638). It influences the chain link D of all chains of general GPS standards.The ISO/GPS Matrix model given in ISO 14638 gives an overview of the ISO/GPS system of which this document is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and the default decision rul
40、es given in this document apply in ISO/GPS, unless otherwise indicated.For more detailed information on the relation of this document to other standards and the GPS matrix model, see Annex B for additional information.The estimated measurement uncertainty is to be taken into account when verifying c
41、onformity or nonconformity with specification.The problem arises when a measured value falls close to the upper or lower specification limit. In this case, verification of conformity or nonconformity with specifications is not possible: the measurement uncertainty induces a probability that a true v
42、alue of the characteristic is out of specification even if the measured value falls inside the specification zone, or is in specification even if the measured value falls outside.Therefore, suppliers and customers should agree in advance in a method to resolve any issues that may arise. This documen
43、t explains how to define default acceptance and rejection zones (i.e. decision rules) for verifying conformity or nonconformity with specifications.It is not the intention of this document to consider any prior knowledge of the possible values of the measurand(s), e.g. the variability of the measure
44、d objects, which may influence the probability of making the correct decision on verification in mathematical terms, an a priori unconstrained maximum entropy distribution (12) is assumed.

45、rement of workpieces and measuring equipment Part 1: Decision rules for verifying conformity or nonconformity with specifications1 ScopeThis document establishes the rules for verifying the conformity or nonconformity with a given tolerance for a characteristic of a workpiece (or a population of wor
46、kpieces) 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.This document applies to specifications defined in general GPS standa
47、rds (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).This
48、document only applies for characteristics and maximum permissible errors expressed as quantity values.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
