除了ISO 15550中定义的基本要求外，ISO 3046-1还规定了功率、燃油消耗量、润滑油消耗量和试验方法的声明要求。 它根据ISO 15550定义了发动机制动功率代码，以便在必要时简化功率声明的应用并促进通信。例如，这适用于发动机铭牌上的功率说明。 ISO 3046-1适用于陆上、铁路牵引和海上使用的往复式内燃机（RIC），也可适用于用于推动道路建设和土方机械、工业卡车以及其他应用的发动机，这些发动机没有适用的国际标准。

ISO 3046-1 specifies the requirements for the declaration of power, fuel consumption, lubricating oil consumption and the test method in addition to the basic requirements defined in ISO 15550. It defines codes for engine brake power in accordance with ISO 15550, in order, where necessary, to simplify the application of the statements of power and to facilitate communication. This applies, e.g., to statements of power used on engine data plates. ISO 3046-1 applies to reciprocating internal combustion (RIC) engines for land, rail-traction and marine use and may be applied to engines used to propel road construction and earth-moving machines, industrial trucks as well as for other applications where no suitable International Standard for these engines exists.
