What is EN ISO 3936:2018?

EN ISO 3936:2018, titled "Road vehicles - Measurement of waste gas emissions from motorcycles and mopeds - Constant volume sampling (CVS) method," is an international standard that provides guidelines for measuring exhaust emissions from motorcycles and mopeds. It specifies the procedure for conducting tests using the Constant Volume Sampling (CVS) method, which is widely accepted as a reliable and accurate method for determining emission levels.

The Importance of Emission Testing

Emission testing plays a crucial role in assessing the environmental impact of vehicles, including motorcycles and mopeds. Harmful gases emitted by these vehicles, such as carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter (PM), contribute to air pollution, smog formation, and adverse health effects. Therefore, it is essential to measure and monitor these emissions to evaluate the compliance of vehicles with regulatory standards and identify potential areas for improvement.

The CVS Method in EN ISO 3936:2018

The Constant Volume Sampling (CVS) method outlined in EN ISO 3936:2018 allows exhaust emissions to be collected and measured under controlled conditions. This method involves extracting a sample of the exhaust gas, diluting it with air, and passing it through various measuring instruments. The concentration of pollutants in the diluted sample is then calculated based on the volume, temperature, and pressure measurements. By following the procedures specified in this standard, consistent and accurate results can be achieved, enabling meaningful comparisons between different motorcycle and moped models.

Benefits and Applications of EN ISO 3936:2018

EN ISO 3936:2018 provides a standardized approach to emission testing for motorcycles and mopeds. It ensures that the measurement process is conducted uniformly, allowing for fair comparisons between vehicles and facilitating the setting of regulatory limits. This standard is beneficial to various stakeholders, including vehicle manufacturers, regulatory authorities, and environmental organizations.

Vehicle manufacturers can use EN ISO 3936:2018 as a reference to develop more environmentally friendly motorcycles and mopeds. By testing and reducing emission levels, manufacturers can improve the sustainability of their products and meet regulatory requirements in different regions.

Regulatory authorities can rely on this standard to define emission limits and enforce compliance by conducting regular inspections and tests. The standardized measurements provided by EN ISO 3936:2018 enable accurate assessments of emissions, leading to effective policies for air quality improvement.

Environmental organizations can utilize this standard to advocate for stricter emission standards and promote sustainable transportation. By referencing EN ISO 3936:2018 in their campaigns, they can raise public awareness about the importance of emission control and encourage individuals to choose vehicles with lower environmental impact.
