摘要一般压力表主要用于液体、气体与蒸汽的压力测量，因广泛应用使得对其开展检定工作责任重大。随着压力表检定工作的深人开展，原检定规程JG52-1999存在一些不适应的地方，国家质量监督检验检疫总局合并了JG52-1999、JJG573-2003两个规程，于2013年6月24日发布了新规程JG52-2013，用于弹性元件式一般压力表、压力真空表和真空表的检定工作。用新旧比对的方法分析新版检定规程的修订内容，对JJG52-2013在使用中的问题进行探讨，并在实际应用的基础上对新版检定规程提出了具体意见及建议。

AbstractPressure 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 verifi-cation 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 verifi-cation 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 JJG522013 are investigated. Some opinions and suggestions on the basis of actual application are also put forward.
