BS EN 60704-2-14:2013+A11:2015 PDF Download

The standards and procedures for measuring the airborne acoustical noise produced by refrigerators, freezers, and cabinets for frozen food are detailed in the BS EN 60704-2-14:2013+A11:2015 standard.

The standard is applicable to all appliances used in homes and other comparable settings, whether they are battery- or mains-powered. The noise measurement techniques described in ISO 3743-1, ISO 3743-2, and ISO 3744 are replaced by this method.

The size of the noise sources and the largest refrigerator, frozen food storage cabinet, or food freezer that shall be employed in the measurements are also specified in the standard. While ISO 3743-1 and ISO 3743-2 have specific requirements for the maximum size of the appliance under test, ISO 3744 is applicable for noise sources of any size.

It is significant to note that the standard does not address standards for the declaration of noise emission values and is instead focused on appliances without an operator present. The standard corresponds to IEC 60704-3 for calculating and verifying noise emission quantities stated in product specifications.

Standard deviations for the declaration and verification of noise emission values as well as projected standard deviations of sound power levels are also included in the standard. The standard includes these values in tables, although they are not mentioned in the explanation.
