IS 16491 : Part 2 : 2025/ISO 13385-2 : 2020 Geometrical Product Specifications (GPS) - Dimensional Measuring Equipment - Part 2 Design and Metrological Characteristics of Calliper Depth Gauges
NATIONAL FOREWORD
This Indian Standard (Part 2) which is identical to ISO 13385-2 : 2020 'Geometrical product specifications (GPS) - Dimensional measuring equipment - Part 2: Design and metrological characteristics of calliper depth gauges' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Engineering Metrology Sectional Committee and approval of the Production and General Engineering Division Council.
This standard was first published in 2016. This revision has been brought out to align it with the latest version of ISO 13385-2.
The following major modifications have been incorporated to the revision of the standard:
a) Figures have been updated to show more modern technology;
b) General design characteristics have been removed and reference to IS 18164 : 2023/ISO 14978 : 2018 included;
c) Metrological characteristics have been clarified and modified;
d) Requirements for test methods have been included; and
e) Requirements for test methods have been included.
This standard has been published in two parts. The other part of this series is:
Part 1 Design and metrological characteristics of callipers
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
