Should pressure gauges on special equipment be subject to mandatory calibration or verification? Should testing and calibration be carried out separately?
Pressure gauges on special equipment must be calibrated compulsorily. Calibration refers to the evaluation and verification of a device’s performance and accuracy through professional measurements and tests. Verification refers to comparing the device under test with known standards or instruments in order to determine its accuracy and make adjustments. Regarding pressure gauges, calibration can detect issues such as air leaks, mechanical damage, or inaccurate readings. Therefore, on special equipment, mandatory calibration of pressure gauges is required to ensure the safety and reliability of the equipment. Generally, testing and calibration can be carried out separately, but they are two different processes that need to be performed independently. .
May I ask which regulation or standard clause specifies this? There seems to be a “Catalogue of measuring instruments subject to mandatory management””
(No. 42, 2020) Announcement by the State Administration for Market Regulation on Adjusting the List of Measuring Instruments Subject to Mandatory Regulation
This does not include everything; the scope is very limited.
It needs to be calibrated once every six months. If you want to cite a basis, give me the specific pressure gauge and I can help you find the exact basis.
Pressure gauges are subject to mandatory calibration every six months
Article 5 states: Can’t you see it? Pressure gauges are subject to mandatory inspection
Don’t you understand? Does the above range include all special equipment?

You may have your own understanding, but the pressure gauges used on special equipment are subject to mandatory inspection; we cannot act according to your understanding. We can only follow the requirements of the regulatory authorities, such as the Special Equipment Inspection Institute, the Market Administration Bureau, as well as those of various users.
If you deal with the Market Bureau and the Special Inspection Institute multiple times, you will understand better. There are also many times when one has to fight for the company’s interests, and one just has to agree with whatever the authorities say.
