| Abstract: | According to requirements of test method for gum content determination and taking determination of gum content in gasoline （including unwashed gum content and solvent Washed gum content for example, the paper discusses the rounding off for numerical values of 0.5 units, the application of expression and judgment of limiting values in data determination process and result assessment of gum content. The purpose is to make data processing, report and result determination more standardized and uniform in testing work of motor gasoline product. |
