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.
