家用和类似用途电器.性能测量方法.重复性 再现性和不确定度的评定

[中文适用范围]： 本技术规范涉及用于评估家用和类似电器的性能特性的测试方法的重复性和再现性的确定。它还提供了进行环形测试（RRT）的指导。它还规定了家用和类似电器测量结果的不确定度报告。它描述了估计测量结果不确定度的方法，并预测当相同的电器在另一实验室应用相同的测量方法时测量值的范围。它不包括测试方法的开发。它也不涉及：家用电器的生产变异；测试方法在多大程度上反映了家用电器在家庭中的正常使用。 [外文原描述]： IEC TR 63250:2021 deals with the determination of repeatability and reproducibility of test methods used for assessing the performance characteristics of household and similar electrical appliances. It also provides guidance for carrying out round robin tests (RRT). It also specifies the uncertainty reporting of measurements of household and similar electrical appliances. It describes methods to estimate the uncertainty of a measured result and to predict the range of measured values when the same appliance is measured in another laboratory applying the same measurement method. It does not cover the development of measurement methods. It also does not deal with: – the production variability of the appliance; – how closely the measurement method reflects the normal use of appliances in households.
