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]： The requirements for setting up and operating the machinery, the microphone array and the size of the hemispherical measurement surface are given in this standard. This standard shall be used in conjunction with ISO 4872-1978, which gives the basic criteria for the acoustic environment, instrumentation, microphone positions, procedures for the measurement of the A-weighted sound pressure levels and the calculation of the A-weighted sound power levels.Cross Reference: ANSI/S1.1,ANSI/S1.13,ANSI/S1.23,ANSI/S1.4,IECPub.651,IECPub.804,ISO1585,ISO4872,ISO6165,J1057,J184_201408,J245,J270
