This standard specifies the method for determining the average relative molecular mass of petroleum samples by viscosity measurement, which is applicable to petroleum samples with relative molecular masses in the range of 250 to 700. This standard does not apply to oils with abnormal composition or narrow molecular Mass range. This method provides an important reference for the analysis and quality control of petroleum products.
