3.Terms and definitions:For the purposes of this document, the terms and definitions given in lS0 14978,ISO/IEC Guide 99,and thefollowing apply.
3.1.calliper:measuring instrument which gives the evaluation of a dimensional quantity of an internal or external feature onthe basis of the movement of a slider with a measuring jaw, moving relative to a measuring scale on a rigidbeam and a fixed jaw See Figures 1 and 2.
NOTE 1 Callipers with an additional measuring face at the end of the beam and a depth measuring rod are used fordepth measurements (see Figure 1).
NOTE 2 The indication may be either analogue (vernier), circular scale or digital. Regarding digital data transfer, see4.3.3.
NOTE 3 See Annex C for examples of different types of callipers.
NOTE4See Annex D for examples of several types of measurements.
3.2.measuring face contact: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.BS EN ISO 13385 pdf download.
