ASTM D3227-23 pdf download – Standard Test Method For (Thiol Mercaptan) Sulfur In Gasoline, Kerosine, Aviation Turbine, And Distillate Fuels (Potentiometric Method).
1.1 The scope of this test method includes the quantification of mercaptan sulfur in gasoline, kerosene, aviation turbine fuels, and distillate fuels, where the concentration of mercaptan sulfur is between 0.0003% and 0.01% by mass. This method is不受干扰 from organic sulfur compounds such as sulfides, disulfides, and thiophene. Additionally, elemental sulfur present in amounts less than 0.0005% by mass does not affect the results. However, hydrogen sulfide can interfere unless it is removed as specified in section 10.2.
1.2 The values presented in acceptable SI units are considered the standard for this test method.
1.2.1 Exception – The values given in parentheses are provided for informational purposes only and are not to be used as the standard.
