JJG52—87弹簧管式一般压力表,压力真空表及真空表JJG49—87弹簧管式精密压力表及真空表国家计量检定规程修订编制说明压力表国家计量检定规程与国家标准由于在某些技术要求上存在着不一致,在实施的过程中给下面带来了许多矛盾。这一问题已引起全国人大代表的注意和议论。为此,国家技术监督局有关部门为了很好协调解决这一问题。于1992年8月21日至24日委托检定规程归口单位上海市技术监督局在山东省烟台认真细致的讨论,反复协商取得了一致意见。有必要对二个规程部分条款作修订,具体修订理由有如下二点:1、根据市场经济发展的需要,标准中规定可以生产二种型号压力表,一种压力表是各检定点不准降低允许基本误差,另外一种压力表在其测量范围的1/10以下和9/10以上的区间允许基本误差可以允许降一个准确度等级,规程为了适应这一情况也作了相应的修改,特在规程表3中作了注解说明。2、为了适应非强检和强检压力表管理工作的需要,对封印问题也作了相应的区别对待的管理办法。详细修订内容见下面的修改单。
JJG52-87 spring tube general pressure gauge, pressure vacuum gauge and vacuum gauge JJG49-87 spring tube precision pressure gauge and vacuum gauge National Metrology and Verification Procedures revised preparation instructions National Metrology gauges and national standards of pressure gauge due to certain technical requirements There are inconsistencies in the implementation process to bring the following contradictions. This issue has drawn the attention and discussion of NPC deputies. To this end, the relevant departments of the State Bureau of Technical Supervision in order to coordinate well solve this problem. From August 21 to August 24, 1992, COSCO Group, the focal point entrusted with the verification procedures, took a serious and meticulous discussion in Yantai, Shandong Province, and obtained unanimous opinions through repeated consultations. There is a need to amend some of the provisions of the two rules, the specific reasons for the amendment as follows: 1, according to the needs of the development of market economy, the standard provides for the production of two types of pressure gauge, a pressure gauge is not allowed to reduce the various test points The basic error is allowed. Another gauge below 1/10 of its measuring range and above 9/10 allows the basic error to be lowered by an accuracy level. The procedure has been modified to accommodate this situation. The rules in Table 3 made a note. 2, in order to meet the non-strong seized and check the pressure gauge management needs, the seal issue also made a corresponding difference between the management approach. For details, see the following amendments to amend the list.
