甲醛标准储备液浓度的不确定度评定
Uncertainty Evaluation of Standardization Concentration of Formaldehyde Standard Solution
-
摘要: 讨论了影响甲醛标准溶液浓度标定值不确定的各种因素,并评定了甲醛标准溶液浓度标定值的不确定度.当甲醛标准溶液浓度为1 058 mg/L时,它的相对标准不确定度为0.70%(K=2).

Abstract: In this paper, some factors influencing the uncertainty of standardization concentration of formaldehyde standard solution are discussed and the uncertainty of standardization concentration of formaldehyde standard solution is evaluated. When concentration of formaldehyde standard solution is 1058 mg/L[JP], the expanded relative uncertainty is 0.70% （K=2）.-
