Foreword
This Japanese Industrial Standard has been revised by the Minister of
Economy, Trade and Industry through deliberations at the Japanese In-
dustrial Standards Committee as the result of proposal for revision of
Japanese Industrial Standard submitted by Japan Precision Measuring
Instruments Manufacturers Association (JMA)/Japanese Standards As-
sociation (JSA) with a draft being attached, based on the provision of Ar-
ticle 12, paragraph (1) of the Industrial Standardization Act applied mu-
tatis mutandis pursuant to the provision of Article 16 of the said Act.
This edition replaces the previous edition (JIS B 7507 : 2016), which has
been technically revised.
However, JIS B 7507 : 2016 may be applied in the JIS mark certification
based on the relevant provisions of Article 30, paragraph (1), etc. of the
Industrial Standardization Act until 19 May 2023.
This JIS document is protected by the Copyright Act.
Attention is drawn to the possibility that some parts of this Standard
may conflict with patent rights, published patent application or utility
model rights. The relevant Minister and the Japanese Industrial Stand-
ards Committee are not responsible for identifying any of such patent
rights, published patent application or utility model rights.

JAPANESE INDUSTRIAL STANDARD JIS B 7507 : 2022
Geometrical product specifications (GPS) — Dimensional
measuring equipment — Vernier, dial and digital callipers
Introduction
This Japanese Industrial Standard has been prepared based on ISO 13385-1 : 2019,
Edition 2, with some modifications of the technical contents to make the standard more
practical and in keeping with the actual manufacture and use in Japan.
Annex JA is unique to JIS and not given in the corresponding International Stand-
ard. The vertical lines on both sides and dotted underlines indicate changes from the
corresponding International Standard. A list of modifications with the explanations is
given in Annex JB.
This Standard is a geometrical product specification (GPS) standard and is to be re-
garded as a general GPS standard (see JIS B 0661). It influences the chain links F and
G of the chain of standards on size and distance in the general GPS matrix. For more
detailed information on the relation of this Standard to other GPS standards, see An-
nex B.
1 Scope
This Standard specifies requirements for callipers equipped with analogue indication
with either a vernier scale or a circular scale, and those equipped with digital indica-
tion.
NOTE The International Standard corresponding to this Standard and the
symbol of degree of correspondence are as follows.
ISO 13385-1 : 2019 Geometrical product specifications (GPS) — Di-
mensional measuring equipment — Part 1 : Design and metrological
characteristics of callipers (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
ISO/IEC Guide 21-1.
