规定了测量和报告计算机和商业设备发出的噪音的程序。基本排放量是A加权声功率级，可用于比较同一类型但来自不同制造商的设备，或用于比较不同设备。为了避免对现有设施和经验的过度限制，规定了两种确定声功率级的方法。与ISO 7779相同，并根据ISO 7779复制。

Specifies procedures for measuring and reporting the noise emitted by computer and business equipment. The basic emission quantity is the A-weighted sound power level which may be used for comparing equipment of the same type, but from different manufacturers, or for comparing different equipment. Two methods for determining the sound power levels are specified in order to avoid undue restriction on existing facilities and experience. Identical with and reproduced from ISO 7779.
