冶金标准物质稳定性的评价

Evaluation on the stability of metallurgical certified reference materials

标准物质的稳定性是标准物质质量的重要指标之一。对各类冶金标准物质进行长期的跟踪试验表明 ,冶金标准物质只要在规定的储存、保管和使用条件下 ,具有比较长期的稳定性。

The stability of metallurgical CRMs is one of the important specification for the quality of CRMs.Through the long-term tracing measurement of different metallurgical CRMs,it shows that metallurgical CRMs have a relevantly long-term stability under the required storage and usage conditions.
