Everyone, does anyone know if there are any **rules or industry standards that require all testing instruments and transmitters in a factory to be calibrated?** (Temperatures, pressure transmitters, flow meters, etc.), thank you
Ask the Work Safety Bureau – transmitters and things of that kind should be required
It is used in four areas: trade, security, environmental protection, and human health, and is subject to mandatory inspection.
**Meters specified in the list for mandatory verification must be verified, while other meters can be calibrated.
Measuring instruments fall under the jurisdiction of the Quality and Technical Supervision Bureau, and it is indeed necessary to have them tested
In accordance with the requirements of the Metrology Law, measuring instruments must undergo value transfer or traceability, and all of them need to be calibrated or verified. For measuring instruments subject to mandatory verification, they must be verified by qualified verification institutions in accordance with the requirements of the verification procedures; for others, it is possible to decide on their own whether to have them verified or calibrated, as well as the frequency of such verification or calibration.
You are referring to the relevant provisions of the Metrology Law. What about the calibration of those level gauges and flow meters? Even if you calibrate it yourself, in terms of value transfer, when someone asks what method or tool you used to do it, how should you respond? There are many things I simply can’t do on my own
