GB/T 4583-1995 in English

《GB/T 4583-1995电动工具噪声测量方法 工程法》由TC68（全国电动工具标准化技术委员会）归口，主管部门为中国电器工业协会。
本标准属于工程级测量方法，适用于各类电动工具（以下简称工具）在稳定运转状态时的噪声测量。为了对工具的辐射噪声给予正确评价和比较，本标准规定A计权声功率级测量方法，其他计权声功率以及频带声功率可以根据需要选择。本标准不适用于具有单个脉冲以及重复率低于每秒10次突发噪声的工具，亦不适用软轴式工具。

Scope

This standard is an engineering-level measurement method, applicable to the noise measurement of various electric tools (hereinafter referred to as tools) in a stable operating state. In order to correctly evaluate and compare the radiated noise of tools, this standard specifies the A-weighted sound power level measurement method, and other weighted sound powers and frequency band sound powers can be selected according to needs. This standard does not apply to tools with a single pulse and a repetition rate of less than 10 bursts of noise per second, nor to flexible shaft tools.
