化学分析用标准物质的期间核查

Interim veri? cation of reference materials for chemical analysis

提出一种用于化学分析用标准物质的核查方法。通过对两个标准样品期间核查数据进行分析,提出判断准则,据此判断该标准物质的量值是否准确可信。期间核查可以有效核查标准物质的量值是否保持原证书规定的状态,为维持其最佳溯源/测量能力、及时发现标准物质的不稳定状态、缩短追溯质量事故的时间、避免错误蔓延扩大提供有效证据。

A verification method was introduced for reference materials for chemical analysis.By analyzing the verification data during the two standard samples,the judgment criteria were put forward.Judging whether the quantity value of the standard material was accurate and credible.The verification during the period could effectively verify whether the quantity value of the standard material maintained the state specified in the original certificate,in order to maintain its best traceability/measurement capability,find the unstable state of the standard material in time,shorten the time of tracing the quality accident,and avoid the spread of error to provide effective evidence as far as possible.
