摘　　要：研制了以硝化棉、硝化甘油、中定剂和凡士林为主要成分的火药比容标准物质,采用方差分析方法检验了标准物质的均匀性,并进行了1a以上的稳定性考核;通过多家单位采用同一原理方法进行标准物质定值,分析评估了标准物质标准值的合成标准不确定度和扩展不确定度,得到标准比容值为627.2L/kg,扩展不确定度为9.0L/kg(k=2)。结果表明,该标准物质特性量值准确、可靠,均匀性和稳定性好,能够满足火药比容量值传递的要求,达到校准和检定火药比容测量仪的目的。A reference material, mainly composed of nitrocellulose （NC）,nitroglycerine （NG）, centralite and vaseline ,was developed for verifying instruments specific volume of propellant. The homogeneity of characteristic value of the reference material was tested by means of the variance analysis method, and its stability had been examined for more than one year. The reference material of propellant specific volume was determined by multi-department based on same principles, and the certified result was 627.2L/kg. The combined standard uncertainty and expanded uncertainty of standard value of reference material were also evaluated, and the expanded uncertainty was determined 9.0L/kg（k=2）. The result showed that the reference material had good homogeneity and stability, its characteristic value was accurate and reliable. The reference material could meet the requirement of transferring the certified value of specific volume, calibrate and verify the instruments specific volume of propellant.
