What is BS EN ISO 4393:2017

BS EN ISO 4393:2017 is an international standard that specifies the methods for measuring and evaluating the sound power level of air-conditioning equipment. This technical article aims to provide an in-depth understanding of this standard, including its scope, requirements, and significance in the field.

Scope of the Standard

The scope of BS EN ISO 4393:2017 covers the measurement of sound power levels emitted by air-conditioning equipment, such as fans, compressors, and condensing units. It applies to both indoor and outdoor units, as well as single- and multi-split systems. The standard provides guidelines for conducting measurements and calculations using defined test conditions and procedures.

Requirements and Testing Procedures

To ensure consistency and accuracy, BS EN ISO 4393:2017 outlines specific requirements and testing procedures that must be followed when measuring sound power levels. These include ensuring proper test conditions, using calibrated equipment, and conducting multiple measurements to account for environmental variations. The standard also specifies the data analysis methods for determining the overall sound power level of the equipment.

Significance and Benefits

BS EN ISO 4393:2017 plays a crucial role in the air-conditioning industry by providing a standardized approach for assessing the acoustic performance of equipment. By implementing this standard, manufacturers can evaluate and compare the noise levels of their products, allowing them to make improvements and develop quieter and more efficient systems. Additionally, the information provided by the standard helps consumers make informed decisions when purchasing air-conditioning equipment, considering factors such as noise levels and overall comfort.

In conclusion, BS EN ISO 4393:2017 serves as a fundamental tool for measuring and evaluating the sound power levels of air-conditioning equipment. It aims to ensure accuracy and consistency in assessing the noise emission, providing manufacturers with guidelines for improvement and consumers with necessary information. By following the requirements and procedures outlined in this standard, the industry can advance towards developing quieter and more efficient air-conditioning systems.
