What is BS EN ISO 13385-2:2020 about?
This updated international specification is the second in a two-part series on callipers: one of the most basic, yet most important instruments used in manufacturing and mechanical engineering. BS EN ISO 13385-2:2020 covers calliper depth gauges.
Who is BS EN ISO 13385-2:2020 for?
It’s aimed at anyone in manufacturing or mechanical engineering who needs to measure the dimensional quantity of a step or the depth of a feature, specifically:
- Mechanical engineers
- Quality control and verification personnel
- Inspection officers
- Metrologists
- Measuring equipment manufacturers and suppliers
- Measuring instrument users
- Laboratories that test and calibrate the instruments
It will be used in many industrial sectors including:
- Aerospace
- Defence
- Automotive
- Nuclear
- Rail
Why should you use BS EN ISO 13385-2:2020?
It specifies the most important and latest design and metrological characteristics of calliper depth gauges with:
- Analogue indication: vernier scale or circular scale (dial)
- Digital indication: digital display
For the first time, BS EN ISO 13385-2:2020 includes default values for maximum permissible errors.
Using the standard helps improve efficiency and manage risk.
NOTE: General design characteristics for calliper depth gauges have been removed from this edition and now appear in the revised version of the generic measuring instruments standard BS EN ISO 14978:2018 Geometrical product specifications (GPS). General concepts and requirements for GPS measuring equipment. BS EN ISO 14978:2018 should be used alongside BS EN ISO 13385-2:2020.
What’s new about BS EN ISO 13385-2:2020?
This revision of the 2011 version aims to make the document more useful. Specifically the main changes are:
a) The figures have been updated to show more modern technology
b) General design characteristics have been removed and reference to ISO 14978:2018 included
c) Metrological characteristics have been clarified and modified
d) Requirements for test methods have been included
Default values for maximum permissible errors have been added
