What is IEC 60704-24 Ed. 2:2018?

IEC 60704-24 Ed. 2:2018 is a technical standard that provides guidelines for measuring the airborne acoustical noise emitted by household and similar electrical appliances. The purpose of this standard is to ensure that consumers are informed about the noise levels produced by these appliances, helping them make an informed decision while purchasing.

Importance of Measuring Airborne Acoustical Noise

Noise pollution has become a significant concern in our modern society. Apart from causing annoyance and discomfort, excessive noise can also have adverse effects on human health, including stress, sleep disturbances, and even hearing loss. Therefore, it is crucial to measure the noise levels emitted by various appliances to promote a quieter and healthier living environment.

Testing Procedure and Requirements

IEC 60704-24 Ed. 2:2018 defines both the testing procedure and the requirements for measuring airborne acoustical noise. The standard specifies various parameters, such as the location and distance of the microphone from the appliance, the measurement setup, and recording procedures. It also provides guidance on calculating the sound power level and sound pressure level.

The appliances covered by this standard include refrigerators, dishwashers, washing machines, vacuum cleaners, and many others commonly found in households. By following the defined testing procedure and adhering to the specified requirements, manufacturers can ensure that their appliances comply with the acceptable noise levels, providing users with quieter homes.

Benefits and Limitations

One of the key benefits of adhering to IEC 60704-24 Ed. 2:2018 is enhanced consumer confidence. When purchasing an electrical appliance, consumers can refer to its noise levels as specified in the product documentation. This transparency allows them to choose appliances that meet their noise preferences and requirements.

However, it is important to note that IEC 60704-24 Ed. 2:2018 focuses on measuring airborne acoustical noise and may not cover other aspects of noise emissions, such as structure-borne or solid-borne noise. Additionally, the standard does not provide any specific noise limits for individual appliance types. Nevertheless, it serves as an essential tool for manufacturers, helping them design quieter and more efficient appliances.
