Foreword This translation has been made based on the original Japanese Industrial Standard revised by the Minister of Economy, Trade and Industry through deliberations at the Japanese Industrial Standards Committee as the result of proposal for revision of Japanese Industrial Standard submitted by Japan Precision Measuring Instruments Association (JMA)/Japanese Standards Association (JSA) with the draft being attached, based on the provision of Article 12 Clause 1 of the Industrial Standardization Law applicable to the case of revision by the provision of Article 14. Consequently JIS B 7507: 1993 is replaced with this Standard.



JIS B 7507: 1993 may be applied in the JIS mark certification based on the relevant provisions of Article 19 Clause 1, etc. of the Industrial Standardization Law until August 21,2017. This JIS document is protected by the Copyright Law. Attention is drawn to the possibility that some parts of this Standard may conflict with patent rights, applications for a patent after opening to the public or utility model rights. The relevant Minister and the Japanese Industrial Standards Committee are not responsible for identifying any of such patent rights, applications for a patent after opening to the public or utility model rights

JAPANESE INDUSTRIAL STANDARD



Vernier, dial and digital callipers Introduction This Japanese Industrial Standard has been prepared based on the first edition of ISO 13385-1 published in 2011 with some modifications of the technical contents in order to correspond to the practical manufacture and use. The portions given sidelines or dotted underlines are the matters in which the contents of the corresponding International Standard have been modified. A list of modifications with the explanations is given in Annex JB. This Standard is one of geometrical product specifications (GPS) under the GPS Basic Standard (see ISO/TR 14638 : 1995) and related to the chain link 5 for the chain of standards on size. The details about the relation of this Standard and other GPS Standard are given in Annex C.



1



Scope



This Standard specifies callipers equipped with analogue or digital indicating devices with either a vernier scale or a circular scale. NOTE:



The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows. ISO 13385-1 : 2011 Geometrical product specifications (GPS) - Dimensional measuring equipment - Part 1 : Callipers; Design and metrological characteristics (MOD) In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISOIIEC Guide 21-1.

Normative references



The following standards contain provisions which, through reference in this text, constitute provisions of this Standard. The most recent editions of the standards (including amendments) indicated below shall be applied. JIS B 0641-1

Terms and definitions



For the purpose of this Standard, the terms and definitions given in JIS B 0641-1, JIS B 0642, JIS_Z__8..lQa and the following apply.



calliper



3.1



measuring instrument which gives the evaluation of a dimensional quantity of an internal or external feature on the basis of the movement of a slider with a measuring jaw, moving relative to a measuring scale A beam has a fixed jaw while a slider has a measuring jaw. NOTE 1



Callipers with an additional measuring face at the end of the beam and a depth measuring rod are used for depth measurements.



NOTE 2



The indication is either analogue (vernier scale or circular scale) or digital. Regarding digital data transfer, see 4.4.3.



measuring face contact



3.2



contact between the measuring face and a feature of a workpiece 3.2.1



full measuring face contact



contact between the full area of the measuring face and a feature of a workpiece 3.2.2



partial measuring face contact



contact between a partial area of the measuring face and a feature of a workpiece 3.2.3



measuring face line contact



contact between a line, perpendicular to the length of the jaws, on the measuring face and a feature of a workpiece NOTE: a~g



Form deviations in either the measuring face(s) or the feature are disregarded for the purposes of these definitions.
