在国际建议R76中,规定了对非自动衡量仪器的检定方法和判定标准,但并未提供用于非自动衡量仪器校准的不确定度评定方法。根据欧盟认可组织发布的EA-10/18《非自动衡量仪器校准指南》(以下简称《指南》)中提供的测量方法和计算公式,笔者给出其中一个校准电子天平的实例,目的在于借此规范我国非自动衡量仪器的校准工作。
In International Recommendation R76, the method and criteria for the determination of non-automatic measuring instruments are specified, but the methods for the assessment of the uncertainty used in the calibration of non-automatic measuring instruments are not provided. According to the measurement methods and calculation formulas provided in the Guide for the Calibration of Non-Automatic Measuring Instruments (hereinafter referred to as the “Guide”) of the EA-10/18 issued by the European Union Accreditation Organization, the author gives one example of calibrating an electronic balance with the purpose of Standardize our non-automatic measurement equipment calibration.
