GB 25199-2017B5 diesel fuels (English PDF)

1 Scope

GB 25199-2017 is the Chinese national standard on b5 diesel fuels, in the field of petroleum and related technologies. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 7 September 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 7 September 2017. Classification: ICS 75.160.20, CCS E31. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the terms and definitions, classifications and markings, requirements and test methods, inspection rules and markings, packaging, transportation, storage and safety of B5 diesel blended from BD100 biodiesel and petroleum diesel. This standard is applicable to B5 common diesel fuel and B5 motor vehicle diesel fuel used in compression-combustion engines with BD100 biodiesel as the blending component.
