标准摘要
[中文适用范围]： 本推荐的做法提供了测试可相对轻松地从一辆卡车切换到另一辆卡车的组件或系统的最低要求；即空气动力装置、离合器风扇、子午线轮胎等。该测试使用在役车队车辆，在代表性路线上运行。被测部件或系统的相对燃油效率被确定为百分比改进因子。该系数是使用使用和不使用所评估的特定组件或系统运行的类似车辆的相对燃油使用量来计算的。采用该测试技术的准确度为+-1% 或+-2%，具体取决于燃料测量方法。 [外文原描述]： This recommended practice provides minimum requirements for testing components or systems of the type which can be switched from one truck to another with relative ease; i.e., aerodynamic devices, clutch fans, radial tires, and the like. The test utilizes in-service fleet vehicles, operated over representative routes. The relative fuel effectiveness of the component or system under test is determined as a percentage improvement factor. This factor is calculated using the relative fuel usage of like vehicles operating with and without the specific component or system under evaluation. Accuracy capability employing this test technique is either ±1% or ±2%, depending upon the method of fuel measured. (See paragraph 7.4 .)Cross Reference:
