一、示值误差的计算与判定在实际检定工作中,部分检定人员仅以压力表轻敲表壳后示值误差作为示值误差是否合格的判定依据,可能原因是认为“检定记录格式”(附录A)上只记录压力表轻敲表壳后的示值。显然,该认识是有偏差的。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》第5.3条规定:“压力表示值误差应不超过表1所规定的最大允许误差”;第7.3.3之C)条规定: First, the calculation and determination of indication error In the actual verification work, part of the verification staff only pressure gauge tapping the case after the indication error as the indication error is the basis for the determination of the error may be that “test record format ”(Appendix A) only record pressure gauge tapping the case after the indication. Obviously, this understanding is biased. JJG52-2013 “elastic components of the general pressure gauge, pressure vacuum gauge and vacuum gauge verification procedures” Article 5.3: “pressure indication error should not exceed the maximum allowable error” specified in Table 1; 7.3.3 C) states:
