It influences the chain link 6 of the chain of standards on roughness, waviness a

35、the basic equipment, a drive unit, a probe and a profile recorder (see ISO 3274). 2 BS EN ISO 12179:2000ISO 97121:(0002)E ISO 0002 All irhgts seredevr 3 If the basic equipment is used with several drive units and probes, each of these instrumental combinations (configurations) shall be calibrated se

36、parately. 4.2 Calibration of a configuration The contact (stylus) instrument shall be calibrated when a change is made to the basic elements of the system which intentionally or unintentionally modifies the measured profile/measuring result. Each configuration of the contact (stylus) instrument shal

37、l be calibrated separately. EXAMPLE With a change of probe the contact (stylus) instrument shall be calibrated. 4.3 Place of calibration The contact (stylus) instrument should be calibrated at the place of use with environmental conditions similar to those present when in use for measurement to take

38、 into account external influence factors. EXAMPLE Noise, temperature, vibration, air movement, etc. 5 Measurement standards The following measuring standards are applicable to the calibrations given in clause 6: optical flat; depth measurement standard (Figure 1): type A according to ISO 5436-1; spa

39、cing measurement standard (Figure 2): type C according to ISO 5436-1; inclined optical flat (Figure 3); profile co-ordinate measurement standard (consisting of a sphere or prism): type E according to ISO 5436-1; roughness measurement standard (Figure 4): type D according to ISO 5436-1. NOTE It is re

40、commended that a profile co-ordinate measurement standard be used on contact (stylus) instruments where the stylus rotates plus and minus one half of a degree when moving through its full range. 6 Contact (stylus) instrument metrological characteristics Only those task-related contact (stylus) instr

41、ument metrological characteristics which are relevant for the intended measurements should be selected for calibration. For example, for the measurement of spacing parameters, the vertical profile component need not be calibrated. 6.1 Residual profile calibration The scratch-free optical flat reprod

42、uces the residual profile. For task-related calibrations use the appropriate profile and parameters (for example: the roughness profile with Ra, Rq or Rt; the waviness profile with Wq or Wt). NOTE By using this approach the effects of external guide straightness, environmental conditions and instrum

43、ent noise can be established. 3 BS EN ISO 12179:2000ISO 97121:(0002)E 4 ISO 0002 All irhgts seredevr Dimension in millimetres Figure 1 Example of a depth measurement standard (type A2) Figure 2 Example of a spacing measurement standard (type C) 4 BS EN ISO 12179:2000ISO 97121:(0002)E ISO 0002 All ir
