摘　　要：研制了低温封接玻璃成分分析标准物质,对标准物质的制备技术进行了研究。分别用F检验和t检验法对研制的标准物质进行了均匀性和稳定性检验,结果表明,研制的低温封接玻璃标准物质具有良好的均匀性和稳定性。采用6家实验室进行协作定值,对定值结果的不确定度进行了评定。各组分定值结果的相对扩展不确定度均小于5%(k=2)。Certified reference material（CRM） of low temperature sealing glass for elements analysis was developed. Preparation technology was introduced. Uniformity test and stability test for CRM were analyzed. The results showed that the homogeneity and stability of the CRM were fine. A cooperative certification was conducted by six labs. The relative expanded uncertainty of characteristic values was less than 5%（k=2）.
