Calibration of measuring instruments and equipment
Thread Content
At petrochemical plant construction sites, measuring instruments and devices such as pressure gauges, hygrometers, ammeters, voltmeters, levels, theodolites, etc., need to be calibrated or verified. If calibration is required, which institution should carry out this task? Which standards specify this? Please advise
The Institute for Measurement Devices that used to be part of the Special Equipment Inspection Institute under the Quality Supervision Bureau; it is now part of the Institute for Measurement Devices under the Market Regulation Bureau
I would like to ask: is it necessary to conduct a calibration or an inspection?
I’d like to ask again: is it calibration or verification that is required?
Inspections are mandatory according to regulations, and the same instrument requires different standards when used in different locations. Verification is something that needs to be done almost every time before use.
Before use, it is necessary to verify which specification requires this. Thank you for your guidance
