This standard specifies the method for measuring the A-weighted sound power level of environmental radiated noise of construction machinery under dynamic test conditions. This standard applies to the following types of crawler and tire construction machinery [see appendix AD (standard appendix)], rolling and mechanical excavators, bulldozers, loaders and backhoe loaders, see GB/T for various machines Figures 2 to 4 of 16710.2-1996.
