Description

“JIS Z 9090 :Measurement-General rules for calibration sistem―Appendix1 : How to determine the calibration period and the correction limit”is a standard to optimize the calibration period of measurement systems.It’s based on the method of Feedback Control in On-line Quality Engineering. But pingauges, etc. are not applicable to this standard. Therefore we examined another methods applicable in that case.After consideration,our conclusion is that the method of Diagnosis and Adjustment is appropriate. And we took the concept calculating the costs by quantifying the risk under a variety of circumstances of calibration.As a result,the calibration period of pingauges in a china plant could be extended to three years from one year.At the same time,the calibration cost could be reduced to one third.
