一、概述1.测量依据JJG99-2006《砝码》检定规程。2.环境条件温度为常温,实验室不允许有容易察觉的振动和气流,温度波动每4h不大于1℃,相对湿度不大于70%。3.测量方法依据JJG99-2006进行检定,采用直接比较法,使用标准天平,将标准砝码直接一对一测量同标称质量的被检砝码,可得到标准砝码与被测砝码之间的差值,将其差加上标准砝码的质量值作为被测等级砝码的测量结果。4.评定结果的使用符合上述条件的测量结果,一般可参照使用本不确定度评定方法。
I. Overview 1. Measurement based on JJG99-2006 “weight” test procedures. 2. Environmental conditions Temperature is normal temperature, the laboratory does not allow easy to detect the vibration and airflow, the temperature fluctuations of not more than 1 ℃ every 4h, relative humidity less than 70%. 3. Measurement method According to JJG99-2006 for testing, the use of direct comparison method, the use of standard balance, the standard weight directly one on one measurement with the nominal weight of the test weight can be obtained standard weights and weights Between the difference, the difference between the standard weight plus the weight value of the measured grade weight measurement results. 4. The use of assessment results in line with the above conditions of measurement results, the general reference to the use of this uncertainty assessment method.
