GB/T 34273-2017 in English

This standard provides a method for calculating the cetane index of distillate fuels produced through coal-based Fischer-Tropsch synthesis using a four-variable formula approach. It outlines the necessary parameters, data collection procedures, and mathematical expressions required to accurately determine the cetane index. The method is applicable to a range of distillate fuels derived from coal-based Fischer-Tropsch synthesis processes. It ensures consistency and reliability in the calculation process by specifying standardized conditions and variables. The standard is intended for use by organizations involved in the production, testing, and quality control of such fuels. It facilitates the comparison of fuel properties and supports the development of specifications for these types of fuels. The procedures described are designed to be practical and suitable for implementation in laboratory settings.
