摘要
JJG 1154-2018《卡尔.费休容量法水分测定仪检定规程》于2018年9月25日实施,规程未对检定的操作细节进行过多描述,在实际检定过程中,常常出现因操作不当导致水分含量示值相对误差和重复性检定结果不能满足规程要求,本文针对这些问题提出一些建议,供大家参考。
JJG 1154-2018"Verification Regulation of Karl Fischer Volumetric Titrators for Water Content"was implemented on September 25,2018.The operation details of verification are not described too much in the regulation.In the actual verification process,the relative error and repeatability results caused by improper operation often can not meet the requirements of regulation.This paper puts forward some suggestions for reference.
