Abstract: Pressure gauges are used for measuring the pressure of liquids, gases and steam, and the verification work becomes responsible because of the extensive application responsibility. With the further development of the pressure gauge verification, there exist some unreasonable places in the original verification regulation JJG49-1999, so the JJG52-1999 and the JJG573-2003 had been combined by the General Administration of Quality Supervision Inspection and Quarantine of the PRC, and the new verification regulation JJG52-2013 was promulgated in June 24 2013.It is used to guide to calibrate the elastic element type pressure gauge, pressure vacuum gauge and vacuum gauge. We contrast the old to the new verification regulation, and the problems in the using of JJG52-2013 are investigated. Some opinions and suggestions on the basis of actual application are also put forward.
