标准摘要
[中文适用范围]： 本国际标准规定了一种测定土方机械发出的外部噪声的方法，该方法用 A 计权声功率级，当机器静止且发动机在空载条件下以额定速度运转时。本国际标准适用于以下特定类型的土方机械： 挖掘机（液压或绳索操作）；履带式和轮式拖拉机推土机；履带式和轮式装载机；和反铲装载机。 [外文原描述]： This SAE Standard describes a method for determining the exterior noise emitted by earthmoving machinery in terms of the A-weighted sound power level while the machine is in a stationary test condition. At six positions on a hemispherical surface, the equivalent continuous A-weighted sound pressure levels are measured. The A-weighted sound power level of the machinery is calculated from the measured values.Cross Reference: IECPub.651,ISO1585,ISO6165,J2101/ISO4872,J2103/ISO6394
