NBN ISO 6826:2019

This International Standard establishes requirements for reciprocating internal combustion engines to minimize the risk of fire caused by the engine, its components and the auxiliaries fitted to it. Where necessary, special requirements can be given for particular engine applications.
The requirements of this International Standard are not intended to enable an engine to operate during or after a fire.
This International Standard covers reciprocating internal combustion engines for land, rail-traction and marine use, excluding engines used to propel agricultural tractors, road vehicles, road construction and earth-moving machines and aircraft.
This International Standard may be applied to engines used to propel industrial trucks and small craft and for other applications where no suitable International Standard for fire protection on reciprocating internal combustion engines exist.
For engine applications excluded above, this International Standard may be used as the basis for engine application standards.
