BS EN IEC 60704-1:2021 PDF Download

A standard that relates to electric appliances used in homes and other comparable situations is BS EN IEC 60704-1:2021. It offers recommendations for calculating the sound power levels of certain equipment, concentrating on airborne acoustical noise within the relevant frequency range.

In reference to a sound power of one picowatt, the standard specifies objective techniques of engineering precision for determining sound power levels, expressed in decibels. It describes the required operating circumstances and measuring frequency range, which typically includes octave-bands with center frequencies between 125 Hz and 8,000 Hz.

It's crucial to remember that BS EN IEC 60704-1 does not apply to appliances created specifically for industrial or professional applications, appliances incorporated into buildings or their installations (with a few exceptions, such as home fans and cooker hoods), separate motors or generators, or appliances created specifically for outdoor use.

Manufacturers and providers of electrical equipment for the home and other similar items should be aware of this standard. It offers a structure for calculating and announcing noise emission values, enabling comparisons between various appliances belonging to the same family, and directing engineering efforts for sound insulation.

The most recent revision, BS EN IEC 60704-1:2021, cancels and replaces the preceding version, EN 60704-1, which was published in 2010. The revised version improves references, particularly to ISO standards, and makes changes to the specifications for weather and background noise levels.
