Test Procedures for Gasoline, Diesel, and Alternative Fuels

This page last reviewed January 29, 2014

For questions or comments related to the ARB's individual SOPs (Standard Operating Procedures) listed in the table below, please contact Yanbo Pang at (626) 575-6692. 

In addition, for a list of other test methods used to enforce ARB's gasoline and diesel fuel regulations, please look at the documents entitled "Gasoline Specifications and Test Methods" and "Diesel Fuel Specifications and Test Methods."

Also, for a list of test methods used to enforce ARB's Alternative Fuels, please look at the individual California Code of Regulations (CCR) (Title 13, Sections 2290 to 2292.7). These include: M-100, M-85, E-100, E-85, CNG, LPG, and Hydrogen. To access the actual CCR language, please go to the OAL Website.
