一般来说,给出示值误差△的测量不确定度U95或k=2时的U与评定测量仪器的最大允许误差的绝对值(MPEP)之比小于或等于1:3时,合格与否的评定可忽略示值误差△的测量不确定度,此时
合格判据为:|△|<= MPEV
不合格判据为:|△|>MPEV
当给出示值误差△的测量不确定度U95或k=2时的U与评定测量仪器的最大允许误差的绝对值(MPEP)之比不满足小于或等于1:3时,合格与否的评定不可忽略示值误差△的测量不确定度,此时
合格判据为:|△|<= MPEV - U95
不合格判据为:|△|>MPEV + U95
待定区:MPEV - U95 <|△|>=MPEV + U95 此时不能判定合格与否。

是不是计量检定规程 JJG 标准。其他的都不行,比如 JJF 就不能?

I have kept silent for several weeks in this forum because my Chinese character inputting device is out of order. May I answer your question in English, sorry.
“不需要考虑对示值误差评定的测量不确定度影响”because of the principle “规程对评定方法、计量标准、环境条件等已作出规定,并满足检定系统表量值传递的要求”. Therefore, no matter the “规程” is called JJG, or JJF, BS, ASTM, ISO……, “不需要考虑对示值误差评定的测量不确定度影响”as soon as the conditions of the above principle is fulfilled.
I have used BS and ISO to calibrate the universal testing machines for many years, uncertainty has never been applied in evaluating the grading of the machine.
