5、National foreword This standard has been prepared by Technical Committee ISO/TC 213 “Dimensional and geometrical product specifications and verification”, Working Group WG 6 “General requirements for geometrical product specification (GPS) measuring equipment” in collaboration with Technical Committ
6、ee CEN/TC 290 “Dimensional and geometrical product specification and verification (Secretariat: AFNOR, France). The responsible German body involved in its preparation was the Normenausschuss Technische Grundlagen (Fundamentals in Technology Standards Committee), Working Committee NA 152-03-02-07 UA
7、 Eindimen-sionale Lngenprftechnik. This standard is a general GPS standard drawn up on the “operator principle” and defines the most important design and metrological characteristics of dial test indicators (lever type). The metrological characteristics serve as the basis for calculating the uncerta
8、inty of measurements carried out with a dial test indicator. At the ISO/TC 213/WG 6 meeting in San Diego on 12 January 1997 it was agreed that all future GPS standards would be drawn up on the “operator principle”, that is, the numerical values for limits of metrological characteristics will no long
9、er be specified in a standard; Germany was against this resolution. The manufacturer will now have to give values for the characteristics required by the relevant standard. This decision is a result of the fact that after years of discussion, ISO/TC 3/WG 11 was not able to come to agreement on the l
10、imit values for permissible errors of “classical” length-measuring devices. The present version of this standard is a result of the above-mentioned resolution. To ensure German industry continues to have access to the limit values for metrological characteristics, a new edition of DIN 2270 has been
11、published, which contains only the above-mentioned limit values. National Annex NB describes the difference between the previous practice in Germany and that specified in the current standard, taking into consideration DIN EN ISO 14253-1. In 1992, CEN/TC 290 “Dimensional and geometrical product spec
12、ification and verification” had already decided not to publish its own standards, but rather strongly recommended that its members be actively involved in drawing up the relevant GPS standards at ISO so that the ISO Standards could be adopted, unchanged, as European Standards. The DIN Standards corr
13、esponding to the International Standards referred to in Clause 2 of the EN are as follows: ISO 286-2 DIN EN ISO 286-2 ISO 14253-1 DIN EN ISO 14253-1 ISO 14253-2 DIN EN ISO 14253-2 ISO/TR 14638 DIN V 32950 ISO 14978 DIN EN ISO 14978 ISO/IEC Guide 98-3 DIN V ENV 13005 ISO/IEC Guide 99 VIM (D) ”DIN EN
14、ISO 9493:2011-03 3 Amendments This standard differs from DIN 2270:1985-04 as follows: a) the numerical values for metrological characteristics are no longer specified; b) the characteristic “span of error” has been replaced by “maximum permissible errors (MPEs)”; c) the characteristic “repeatability
15、” has been replaced by the “repeatability of error of indication (MPER)”; d) the definitions of the metrological characteristics are now included in the framework standard ISO 14978; e) the title of the standard has been changed; f) the standard has been editorially revised.

DIN EN ISO 9493:2011-03 4 National Annex NB (informative) Comparison of previous practice with that specified in this standard DIN EN ISO 9493 differs from DIN 2270:1985 largely as follows: a) the numerical values for maximum permissible errors (MPEs) are no longer stan
21、dardized, but are to be specified by the manufacturer; b) the limits for the hysteresis, repeatability and error of indication are to comply with the manufacturers specifications at any position within the measuring range. Another major change in the approach to errors is the implementation of DIN E
22、N ISO 14253-1 which specifies how uncertainty is to be used when measurements are made to prove conformance or non-conformance with a specification. The manufacturer proves conformance with the specification, according to DIN EN ISO 14253-1, when the measurement result lies in the conformance zone (
23、see Figure NB.1). The user proves non-conformance with the specification, according to DIN EN ISO 14253-1, when the measurement result lies in the non-conformance zone (see Figure NB.1).
