等同地采用ISO 9249:2007，该标准规定了用于推进ISO 6165中定义的土方机械的往复式内燃机净功率的测试方法。其目的是提供一种向土方机械最终用户报告净功率值的标准化方法。它适用于RIC火花点火或压燃式发动机，但不包括自由活塞发动机和旋转活塞发动机。关键词:往复式内燃机；土方测试代码净功率；RIC火花点火发动机；RIC压燃式发动机。

Identically adopts ISO 9249:2007, which specifies a method for testing the net power of reciprocating internal combustion engines intended for the propulsion of earth-moving machinery as defined in ISO 6165. It is intended to provide a standardized means of reporting net power values to the end user of the earth-moving machines. It is applicable to RIC spark- or compression-ignition engines, but excluding free piston engines, and rotary piston engines.KEYWORDS: Reciprocating internal combustion engines; Earth-moving test code net power; RIC spark-ignition engines; RIC compression-ignition engines.
