28、 documents (see ISO 14638). It influences chain link F of all chains of standards in the general GPS matrix.The ISO/GPS matrix model given in ISO 14638 gives an overview of the ISO/GPS system of which this international standard is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to

29、this part of ISO 14253 and the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this part of ISO 14253, unless otherwise indicated.For more detailed information about the relationship of this part of ISO 14253 to other standards and to the GPS matrix model,

30、 see Annex B.Decision rules for deciding conformity or non-conformity to specifications are based on the measurement uncertainty incurred while testing.Usual practice in measurement familiarizes metrologists and practitioners with measurement uncertainty. Any possible effect that may affect the meas

31、urement result is considered and quantified as an uncertainty component and is eventually included in the combined uncertainty. The purpose of the measurement is to gather quantitative information on a given measurand, and the uncertainty statement expresses how reliable that information is.In the c

32、ase of tests of indicating measuring instruments, the purpose of the measurement is to investigate one or more metrological characteristics of the indicating measuring instrument rather than to measure characteristics of features of a workpiece. The uncertainty being evaluated in this case, the test

33、 value uncertainty, quantifies the accuracy of the test value. The test detects the quality of the indicating measuring instrument, reported through the test values and not through the test value uncertainty.The test value uncertainty for indicating measuring instruments is not conceptually trivial

34、to evaluate, and careful consideration is necessary to determine which uncertainty components should and which should not be accounted for.Some tests of indicating measuring instruments may be relative to quantities other than instrument indications, or a single test may investigate both the instrum

35、ent indication(s) and other metrological characteristics. An example is a test of a micrometer investigating the indication error (subject to an MPE) as well as the measuring force (subject to an MPL). For tests, or portions of them, relative to metrological characteristics other than instrument ind

36、ications, this part of ISO 14253 is not applicable: they are about quantities for which the application of the ISO/IEC Guide 98-3 (GUM) and of the ISO 14253-2 is conceptually straightforward, with no need of further guidance in this part of ISO 14253.A rigorous definition of the test value uncertain

37、ty when testing indicating measuring instruments is given. Application of conventional uncertainty evaluation based on this definition and according to the ISO/IEC Guide 98-3 (GUM) and the ISO 14253-2 determines which uncertainty components to account for.

38、53-5:2015BS EN ISO 14253-5:2015Geometrical product specifications (GPS) Inspection by measurement of workpieces and measuring equipment Part 5: Uncertainty in verification testing of indicating measuring instruments1 ScopeThis part of ISO 14253 specifies concepts and terms for evaluating the uncerta

39、inties of the test values derived according to a test protocol agreed upon by the parties and relative to instrument indication(s), obtained in verification testing of GPS indicating measuring instruments.NOTE The uncertainty of the test values, referred to as test value uncertainty, is not to be co

40、nfused with the measurement uncertainty associated with using that indicating measuring instrument to measure workpieces. The former only is covered in this part of ISO 14253; for guidance on the latter see the ISO/IEC Guide 98-3 (GUM) and ISO 14253-2.When a test of an indicating measuring instrumen

41、t comprises several test values, some relative to the instrument indication and some to other metrological characteristics, this part of ISO 14253 is concerned with the uncertainty of the former only.This part of ISO 14253 does not provide guidelines to ensure the adequacy of a test protocol; rather

42、, once a test protocol is given, it describes how to evaluate the consequent test value uncertainty.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
