ISO 1680:2013规定了在标准化条件下有效执行旋转电机噪声排放特性测定、声明和验证所需的所有信息。它规定了可使用的噪声测量方法,并规定了测试所需的操作和安装条件。
噪声发射特性包括声功率级和发射声压级。这些量的测定是必要的:比较机器发出的噪音;使制造商能够申报排放的噪声;用于噪音控制目的。
将ISO 1680:2013用作噪声测试规范,可确保在所用基本噪声测量方法的精度等级确定的规定限值内,测定噪声发射特性的再现性。
ISO 1680:2013允许的噪声测量方法有精密法(1级)、工程法(2级)和测量法(3级)。优先采用工程等级(2级)的方法。
ISO 1680:2013适用于任何长度、宽度或高度的旋转电机。
ISO 1680:2013 specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration, and verification of the noise emission characteristics of rotating electrical machines. It specifies noise measurement methods that can be used, and specifies the operating and mounting conditions required for the test.
Noise emission characteristics include the sound power level and emission sound pressure level. The determination of these quantities is necessary: to compare the noise emitted by machines; to enable manufacturers to declare the noise emitted; for noise control purposes.
The use of ISO 1680:2013 as a noise test code ensures the reproducibility of the determination of the noise emission characteristics within specified limits determined by the grade of accuracy of the basic noise measurement method used. Noise measurement methods allowed by ISO 1680:2013 are precision methods (grade 1), engineering methods (grade 2) and survey methods (grade 3). Methods of engineering grade (grade 2) are preferred.
ISO 1680:2013 is applicable to rotating electrical machines of any length, width or height.
