Verification cycle analyses and discussions for measuring instruments in enterprises
Qi Li · China Measurement & Testing Technology · 2008
The verification cycle of measuring instruments was affected by certain synthetic factors such as their operating performance,environment,frequency,accuracy requirements,maintenance and storage,and so on.Thus it is a very complex system project to estimate their verification cycles reasonably.The verification cycle estimation was always influenced by the human factor,which was not reasonable.According to present status,the in-use measuring instruments may be invalid,but the overdue measuring instruments may be valid,which indicates that there are many improvements needed for verification cycle evaluation.In this article,the possible problems encountered in verification cycle evaluations and their effects,the verification cycle evaluation,and the adjustment and its documents were analyzed and discussed to introduce the method for evaluating the verification cycles of measuring instruments in enterprises.
