【Help Request】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 – which standards specify this? I would appreciate guidance from experts
There are many aspects involved; first, see what it is used for, and then look up the corresponding technical specifications.
You can check the relevant products listed in the “Catalogue of Measuring Instruments Subject to Regulation under the Law of the People’s Republic of China”; for these products, there are corresponding calibration standards.
Reference can be made to SH/T 3551-2013 \"Code for Acceptance of Construction Quality of Petrochemical Instrumentation Projects\" and GB50093-2013 \"Code for Construction and Quality Acceptance of Automation Instrumentation Projects\".
