This paper describes the standard method for the determination of the total active sulfur in light petroleum fractions by potentiometric titration, the NB / SH / T 0915-2015 “Determination of total active sulfur in light petroleum fractions by potentiometric titration”. The repeatability and reproducibility of the method were verified, and the detection limit of the method was confirmed. The method adopts the conventional instrument, the method is simple, rapid and easy to operate, and the measurement result has good repeatability and can be used for the determination of the total active sulfur value in the light petroleum fraction. NB / SH / T 0915-2015 came into effect on March 1, 2016.
