BS ISO 362-2:2009

Comprehensive Acoustic Measurement Standard for Vehicles

BS ISO 362-2:2009 is the definitive standard for measuring the exterior noise of vehicles under different operating conditions. Developed by the International Organization for Standardization (ISO), this standard ensures compliance with the latest international regulations and provides a robust framework for assessing vehicle noise levels.

Detailed Technical Specifications

This standard covers a wide range of technical requirements and test procedures, including:• Microphone positioning and measurement conditions• Vehicle operating modes and test speeds• Instrumentation and calibration requirements• Data processing and reportingThe standard specifies the necessary equipment, setup, and methodologies to obtain accurate and reproducible measurements of vehicle noise emissions. This ensures a consistent and reliable approach across different testing facilities and manufacturers.

Ensuring Compliance with Regulations

Compliance with BS ISO 362-2:2009 is essential for vehicle manufacturers and testing laboratories to demonstrate adherence to the latest noise regulations. The standard aligns with the requirements of the UN Regulation No. 51 on the uniform provisions concerning the approval of motor vehicles having at least four wheels with regard to their sound emissions.By following the guidelines set forth in this standard, organizations can:• Verify that their vehicles meet the prescribed noise limits• Identify areas for noise reduction and optimization• Provide reliable data for type approval and homologation processes
