违反标准受法律追究本标准规定了气动与电动手工具(下称机器)的噪声特性标准及其检验方法。 1. 标准 1.1 机器的噪声特性是在中心频率为 63、125、250、500、1000、2000、4000、8000赫芝的倍频带中的声功率级。 1.2.机器在倍频带中的声功率级不能超过表1中的值。如果在具体型号的机器,模型的标准技术文件中或按照与订货人签订的合同,规定机器的班内定额使用系数a小于1,那末噪声的最大值应按下式确定〔L_pj〕=L_pj+△L_pj, (1)
Violation of the standard is subject to legal prosecution This standard specifies the noise characteristics of pneumatic and electric hand tools (hereinafter referred to as machines) and their inspection methods. 1. Standard 1.1 The noise characteristic of the machine is the sound power level in the octave band with center frequencies of 63, 125, 250, 500, 1000, 2000, 4000, and 8000 Hz. 1.2. The sound power level of the machine in the octave band shall not exceed the values in Table 1. If in the specific model of the machine, in the standard technical documentation of the model or in accordance with the contract with the orderer, it is stipulated that the in-class fixed use factor a of the machine is less than 1, the maximum value of the noise shall be determined by the following formula: [L_pj] = L_pj + △ L_pj, (1)
