Scope

The methane number of a gas quantifies the knock propensity of that gas when used as a fuel in a reciprocating internal combustion engine. The higher the methane number, the more knock resistant the gaseous fuel is, and vice versa.

This document defines the MNc method for the calculation of the methane number of a gaseous fuel, using the composition of the gas as sole input for the calculation.

This document applies to natural gas (and biomethane) and their admixtures with hydrogen, see Clause 5.
