实验室常用玻璃量器检定不确定度的评定

Evaluation of Uncertainty for the Verification of Working Glass Container

依据《常用玻璃量器检定规程》（JJG196-2006）,分别采用A类、B类方法,以蒸馏水为介质,用衡量法测量,对农业部食品质量监督检验测试中心实验室中常用玻璃量器在0.5~2000 m L的测量范围内的不确定度来源进行了分析。本不确定度评定的结果可直接使用;对于其它类型和测量范围的常用玻璃量器可采用本不确定度评定方法给出相应的评定结果。

In the lab of supervision and inspection testing center of foods quality（Shihezi）, ministry of agriculture, according to verification regulation of working glass container（JJG196-2006）, we have evaluated the uncertainty in volume measurement of common volumetric glass wares which capacity of 0.5~2000 m L by utilizing weigh methods of category A and B, under standard conditions and distilled water as medium. The evaluation of uncertainty results can been applied directly or extended other type and volume of common volumetric glass wares.
