  • The standard method for determining the cetane number of a diesel fuel is the ASTM D613 method which uses the Cooperative Fuel Research Committee (CFR) engine technique. The procedure, which was introduced in 1941, determines the cetane number of a diesel fuel comparing its ignition quality with two reference blends of known cetane number under the same operating conditions. The method uses a single-cylinder CFR engine operated under specified conditions and the cetane number scale is based on the two reference fuels. ASTM D613 has been used for many years but is known to be a time consuming test of limited precision. It also requires skilled operators.
