1、 International standards
- IEC 60704-1:2021
-This is an international standard specifically designed for noise detection of household and similar electrical appliances. It provides a unified testing method to ensure comparability and consistency of noise detection results between different products and manufacturers. By following the IEC 60704-1:2021 standard, manufacturers can ensure that their products comply with global noise control requirements.
-This standard not only helps the product gain a better reputation in the market, but also assists manufacturers in meeting regulatory requirements in various regions and avoiding legal risks caused by noise issues.
2、 National standards
-Standard for Urban Regional Noise in the People's Republic of China
-This standard specifies the maximum limit of environmental noise in five types of urban areas, including recuperation areas, high-end villa areas, and high-end hotel areas, with a daytime noise level of 50dB and a nighttime noise level of 40dB. These standards provide a reference basis for noise detection of IT products in different environments.
-When measuring indoor noise, the indoor noise limit is 10dB lower than the standard value in the area. This means that when conducting IT product noise detection, it is necessary to consider the impact of environmental noise and take corresponding measures to ensure the accuracy of the detection results.
3、 Other relevant standards
- ISO 7027
-This standard is applicable to turbidity measurement. Although it is not directly aimed at IT product noise detection, its prescribed measurement methods and technical requirements can provide reference for IT product noise detection.
- ASTM D2414
-This standard specifies the composition, technical requirements, performance indicators, and detection methods of portable monitoring instruments for total hydrocarbons, methane, and non methane total hydrocarbons. Although mainly used for the detection of total hydrocarbons in ambient air and fixed pollution source exhaust gases, the detection techniques and methods involved can also be borrowed from IT product noise detection.
4、 Summary
-The industry standards for noise detection of IT products mainly include international standards and national standards, such as IEC 60704-1:2021 and the "Urban Area Noise Standard of the People's Republic of China". These standards provide a unified testing method and evaluation criteria for IT product noise detection, which helps ensure that the noise control of the product meets relevant requirements.
-In addition, other relevant standards such as ISO 7027 and ASTM D2414 can also provide reference for noise detection in IT products. Although they are not directly aimed at noise detection, the measurement techniques and methods involved can be borrowed from IT product noise detection.
