Abstract: The newly implemented Beijing local gasoline standard and the soon-to-be-implemented motor vehicle ethanol gasoline standard (GB 18351) have designated GB/T 34100 as the arbitration standard for the determination of sulfur content. At present, the domestic standards for the determination of sulfur content in light fuel oil by ultraviolet fluorescence method are GB/T 34100-12017 and SH/T 0689-12000, both of which adopt ASTM D5453, but the corresponding versions are different. In view of the doubts in the use of the national standard and the industry standard for the determination of sulfur content in oil products by ultraviolet fluorescence method, this paper expounded the development and changes of the standard for the determination of sulfur content by ultraviolet fluorescence method, and introduced the preparation, revision and development process of standard ASTM D5453. The differences between SH/T 0689, GB/T 34100 and ASTM D5453 were compared, and the shortcomings of the existing methods and the requirements for improvement were pointed out.
