Is it true that all instruments and equipment used for measurement in factories need to be calibrated and measured? Or according to the requirements of the purpose of use to do measurement calibration?

No.

Some instruments need to be tested, some need to be calibrated. Inspection is also divided into mandatory inspection and non-mandatory inspection, non-mandatory inspection is equivalent to calibration. If it belongs to the "trade calculation, environmental monitoring, safety protection, medical and health" four aspects belong to the category of mandatory inspection, we have to do mandatory testing, can not do calibration.

If you need to calibrate, refer to the instrument classification management inside the A, B, C to determine the main categories are as follows:

A class of instruments and equipment

a) for the traceability of the enterprise's highest measuring standard and supporting equipment

b) for trade settlement, safety and security, medical and health care, environmental monitoring, resource protection, statutory evaluation, fairness, and measurement of measuring instruments

b) for trade settlement, safety and security, medical and health care, environmental monitoring, resource protection, statutory evaluation, fairness, and measurement of measuring equipment

b) for trade settlement, environmental monitoring, resource protection, statutory evaluation, fairness Measuring instruments for measurement

c) Measuring equipment for final quality inspection and testing of products

?

Category B Instruments and Equipment

a) Measuring equipment used for critical process control and quality inspection in the production process

b) Measuring equipment used for internal energy and material settlement in various departments;

c) Measuring equipment used to provide the data required for determining the conclusions of the test in the scientific research and technical tests;

d) Specialized measuring equipment that Limit the scope of application of the measurement equipment

C Instruments and equipment

a) production and management process, only used as qualitative monitoring of the measurement equipment;

b) the state allows a one-time use or in the validity period of the use of the measurement equipment;

c) only general instructions, belonging to the measurement of low-value consumables equipment;

d) equipment on the supporting Fixed installation, not easy to disassemble, or disassembly will cause damage to the normal use of equipment, and no strict accuracy requirements for the indication of the measurement equipment

Category A instrument measurement confirmation interval shall not exceed the state's longest confirmation interval, strictly in accordance with the national calibration regulations or calibration specifications for verification/calibration.

Category B according to the organization of the measurement of the confirmed interval measurement verification or calibration.

Category C do a one-time inspection or calibration. Category C is a one-time verification (first inspection) and measurement confirmation.

If you are interested in learning more about the basics of metrological calibration and verification, you can attend the "Metrological Administrator", "Metrological Calibrator", "Enterprise Metrology Training" and other training courses at KWQI. "

These courses are designed to help you learn the basics of measurement calibration and verification.
