随着弹性元件式一般压力表的品种规格越来越多,JJG52-1999《弹簧管式一般压力表、压力真空表和真空表》的局限性、覆盖面小的问题逐步凸显出来。2013年12月24日,将JJG52-1999和JJG573-2003《膜盒压力表》两个检定规程合成一个检定规程进行修订,形成JJG52-2013《弹性元件式一般压力表、压力真空表和真空表》检定规程,以替代原有的检定规程。文章对一般压力表检定过程中执行JJG52-2013检定规程过程中的关键性技术要求谈了几点体会。
With the elastic component type pressure gauges more and more variety specifications, JJG52-1999 “spring tube general pressure gauge, pressure vacuum gauge and vacuum gauge,” the limitations of the coverage of the small problems gradually become apparent. December 24, 2013, the JJG52-1999 and JJG573-2003 “diaphragm pressure gauge” two test protocols into a test protocol revision, the formation of JJG52-2013 “elastic element type general pressure gauge, pressure vacuum gauge and vacuum gauge ”Test procedures to replace the original test procedures. The article talked about the key technical requirements of the JJG52-2013 verification procedures in the process of verification of general pressure gauges.
