What is EN ISO 14143-1:2021?

EN ISO 14143-1:2021 is a professional technical standard that provides guidelines for the measurement, analysis, and interpretation of sound emissions from machinery using sound intensity. It outlines the procedures and requirements for carrying out sound intensity measurements and determining sound power levels.

The Importance of EN ISO 14143-1:2021

Sound emissions from machinery can have significant implications for worker safety, environmental impact, and overall comfort in industrial and commercial settings. EN ISO 14143-1:2021 plays a crucial role in ensuring accurate and standardized measurement of sound emissions, facilitating effective noise control and regulation in various industries.

The standard enables manufacturers to assess and improve their machinery designs to meet legal limits and user expectations regarding noise levels. It also provides a common approach for testing laboratories, enabling reliable comparison of sound emissions data from different sources across industries.

Key Features of EN ISO 14143-1:2021

EN ISO 14143-1:2021 specifies the instrumentation requirements, measurement procedure, and data interpretation methods for sound intensity measurements. It covers the necessary calibration steps, measurement uncertainty estimation, and reporting guidelines.

The standard defines specific measurement positions and procedures for different types of machinery, ensuring consistent and representative sound intensity data are obtained. It also specifies the necessary characteristics of sound intensity probes and their correct usage for accurate measurements.

Benefits and Applications

EN ISO 14143-1:2021 offers several benefits to manufacturers, testing laboratories, and regulatory bodies. By complying with this standard, manufacturers can enhance their product quality and marketability by ensuring compliance with noise emission regulations. It also aids in reducing occupational health risks associated with high noise levels for workers.

Testing laboratories can rely on the specified procedures and requirements to obtain accurate and comparable measurement results. This enables them to offer reliable testing services to manufacturers and supports consistent assessment of machinery noise emissions across different industries.
