本文件规定了往复式内燃机的要求，以将发动机、其部件和安装在其上的辅助设备引起的火灾风险降至最低。必要时，可针对特定发动机应用提出特殊要求。 本文件适用于陆上和海上往复式内燃机，不包括爆炸性环境中使用的发动机、道路车辆和飞机。 本文件也适用于推进小型船舶的发动机以及往复式内燃机没有适用的国际防火标准的其他应用。 对于上述排除的发动机应用，本文件可用作发动机应用标准的基础。

This document 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. This document applies to reciprocating internal combustion engines for land and marine use, excluding engines used in an explosive atmosphere, road vehicles and aircraft. This document can also apply to engines used to propel small craft and for other applications where no suitable International Standard for fire protection on reciprocating internal combustion engines exists. For engine applications excluded above, this document can be used as the basis for engine application standards.
