Compulsory verification catalog of measuring instruments are required to compulsory verification?

No, not all measuring instruments have to be calibrated. A large number of measuring instruments and equipment only need to be calibrated. Inspection is only China's government administrative behavior, is for China's special market environment and the development of this is not from the technical point of view of the behavior. What is common internationally is calibration. On the verification and calibration, because there are really many people, including some of the more professional personnel, do not have a too clear concept, so most enterprises and institutions will be the unit of measurement of the unit's instruments sent to the Technical Supervision Bureau of a brain for verification. In fact, many instruments, if the unit has a standard substance (which belongs to the unit's highest measurement standard apparatus, should be calibrated). As long as they carry out regular calibration can be.

Compulsory calibration of measuring instruments, not only in the national mandatory calibration catalog, but also depends on the use of the instrument. The People's Republic of China *** and the State Measurement Law "Article IX:" the people's government at or above the county level measurement of the administrative departments of the social public measurement standard instruments, departments and enterprises, institutions, the use of the highest measurement standard instruments, as well as used for trade settlement, safety and security, medical care and health, environmental monitoring, listed in the directory of the work of the strong inspection of measuring instruments, the implementation of mandatory verification. Not in accordance with the provisions of the application for verification or verification failed, shall not be used." Please focus on, only "social common measurement standard apparatus", "the highest measurement standard apparatus", "for trade settlement, safety and security, medical and health, environmental monitoring aspects" Listed in the catalog of compulsory inspection of the work of measuring instruments need to be checked.

For example: weighing, balances and so on, if it is used in the shopping malls or markets to buy and sell settlement, it must be verified, to have a qualified mark to use. If this weighing or balance is used for your company in the process of weighing a product dosage, this weighing or balance only need to use the standard material calibration on a regular basis, that is to say, as long as the traceability of the value of the purpose, clear the balance of the value of the error and in the permissible range, you can still use.

Another example is the steel plate ruler and so on, if used in the market to sell cloth (sold by length) must be calibrated. If it is used for in-house undercutting in a garment factory, it only needs to be calibrated.
