Difference between verification and calibration

test

All work to determine whether the metrological characteristics of measuring instruments meet the legal metrological requirements , Do not modify the measurement results .
Verification regulation ： Legal technical documents that must be observed when verifying measuring instruments .

calibration

Under certain conditions , To determine the measuring instrument 、 Measure the quantity or physical instrument indicated by the system 、 A group of operations of the relationship between the quantity represented by the reference material and the quantity reproduced by the measurement standard .
notes ：1. The calibration result can assign a value to the indicated value , It can also determine the correction value of the indicated value .
2. Calibration can be used to determine other metrological characteristics , For example, the effect of influence quantity .
3. The calibration results can be recorded in documents such as calibration certificates or calibration reports .
4. Sometimes, the calibration results are characterized by correction values, calibration capacity factors or calibration curve tables .
5. Sometimes calibration is also called calibration .
6. The calibration can be based on international standards 、 National standard 、 Ministerial standards 、 Calibration specifications 、 Verification regulation 、 Common testing methods in the industry 、 Scientific papers, etc .
