Issues related to the establishment of a calibration facility for pressure gauges in the instrument workshop
Thread Content
Pressure gauges are sent for inspection frequently; if I set up my own testing facility, how should I handle the necessary procedures?
It’s quite complicated; a site can only be established after approval by the local metrology and quality supervision authority. There are also many requirements; qualified personnel are needed as well, it’s difficult!
First, standards need to be established, followed by training to obtain certificates for inspectors; only then is it possible to conduct inspections on one’s own, but this is only applicable to items other than Category A – those in Category A still need to be sent for inspection
Purchase standard instruments in accordance with the requirements of JJG 52-2013 \"General Pressure Gauges, Pressure-Vacuum Gauges, and Vacuum Gauges Based on Elastic Elements\", prepare the necessary documents as specified in JJF1033—2008 \"Specifications for the Evaluation of Metrological Standards\", and submit an application to the local municipal-level technical supervision department for the establishment of a standard.
JJF1033—2008 \"Specifications for the Evaluation of Metrological Standards\"; reference materials and standard instruments. JJG 52-2013 \"General pressure gauges, pressure-vacuum gauges, and vacuum gauges with elastic elements\" – procedures for operation, requirement that personnel hold a metrological registration engineer qualification, submission of an application to the local municipal technical supervision department for standard establishment, on-site evaluation, and approval to carry out calibration activities
Unless you are a large state-owned enterprise, avoid any attempts to cut corners regarding quality inspection.
