The instrument shall also be fitted wit

29、h a slip arrangement such that the measuring force cannot exceed the following: internal diameter up to 100 mm: (4,5 0,2) N; internal diameter over 100 mm: (9,0 0,3) N.6.2.2 ProcedureBefore using, the device should be calibrated with the help of a calibration ring. To get accurate results, use, if p

30、ossible, a measurement plate or a centring ring. Avoiding any obvious deformation, insert the tri-point micrometer at least 10 mm from one end of the test piece in a way that device is accurately in core direction. Take two measurements, to the nearest 0,025 mm, approximately 60 apart. Repeat the pr

Average the four readings and report to the nearest 0,025 mm.6.3 Method B6.3.1 ApparatusA vernier calliper accurate to at least 0,1 mm (see ISO 13385-1).6.3.2 ProcedureAvoiding any obvious deformations, insert the calliper into the test piece such that the

32、 measuring faces are aligned axially and radially. Take two measurements, to the nearest 0,1 mm, 90 apart. Repeat the procedure at the other end of the test piece. Average the four readings and report to the nearest 0,1 mm.6.4 Method C6.4.1 ApparatusA solid round mandrel with external diameters span

33、ning the accuracy range for the diameter to be measured. The mandrel is stepped over its length and graduated in increasing diameters of 0,1 mm with a diameter tolerance of 0,01 mm and each step having a minimum length of 50 mm.An example of a solid mandrel is given in Figure 2.6.4.2 ProcedureInsert

34、 the mandrel into the test piece until a push fit is obtained and note the graduation at this point. Repeat this procedure at the other end of the test piece.
