相对不确定度合成方法在商品包装空隙率不确定度评定中的应用

Application of Synthetic Method of Relative Uncertainty in Uncertainty Evaluation of Voidage of Commodity Packaging

介绍了测量模型的函数为各输入量的乘积时,可由输入量的相对标准不确定度计算出输出量的相对标准不确定度的简化方法,并将该方法应用于商品包装空隙率测量不确定度评定实例中,对JJF1244-2010《食品和化妆品包装计量检验规则》不确定度评定具有参考价值。

When the function of the measurement model is the product of each input quantity,the simplified method of calculating the relative standard uncertainty of the output quantity from the relative standard uncertainty of the input quantity is introduced.The method is applied to the evaluation of the uncertainty of the measurement of the voidage of commodity packaging,which has reference value for the uncertainty evaluation of JJF 1244-2010"Rules of Metrology Testing for Package of Food and Cosmetics".
