摘　　要：为保证分析测量结果的准确可靠,研制了浓度为1000μg/mL的红外测油仪用溶液标准物质。以称量-容量法制备,计算结果定值,对原料进行了纯度分析、制备方法控制,考察了样品均匀性和稳定性,评定了所配制标准物质浓度定值的不确定度。通过与GBW(E)130171比对,验证了标准物质的定值结果准确可靠,相对扩展不确定度<2%(k=2),有效期限为12个月。该标准物质已被批准为国家二级标准物质。To ensure the accuracy and reliability of measurement results,the authors developed a kind of reference material（RM） used by the infrared oil content analyzer with the gravimetric-volume method.The reference concentration of the developed RM is 1 000 μg/mL,which was validated with GBW（E） 130171.And its uncertainty was 2%（k=2）,which was evaluated through analyzing the components caused by the purity of raw materials,preparation,homogeneity and stability of the RM,etc.The RM has been approved as the secondary certified reference material,and its validity period is 12 months.
