Title: What is the IEC standard for conducted emission test?

Introduction:

The environment is an essential resource that we need to protect, and vehicles are one of the major contributors to air pollution and noise pollution. As such, conducting emission tests is crucial in assessing the environmental impact of vehicles and ensuring compliance with regulations regarding air quality and noise pollution. In this article, we will explore the IEC standard for conducted emission tests, EN 52325, and the international standard, EN ISO 3936:2018, which provide guidelines for measuring exhaust emissions from motorcycles and mopeds using the Constant Volume Sampling (CVS) method.

What is EN 52325?

EN 52325 is a technical standard developed by the European Committee for Standardization (CEN) that focuses on the measurement of emissions from road vehicles. It provides specifications and procedures for testing various emission parameters, including exhaust gases, particulate matter, and noise levels. This standard aims to ensure that vehicles meet stringent environmental requirements and comply with regulations regarding air quality and noise pollution. It is applicable to all types of road vehicles, ranging from cars and motorcycles to trucks and buses. By setting uniform guidelines for emission testing, EN 52325 promotes consistency and comparability across different vehicle models and manufacturers.

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 using the Constant Volume Sampling (CVS) method. The CVS method is a reliable and accurate method for determining emission levels, and EN ISO 3936:2018 provides a standardized procedure for conducting these tests.

The Importance of Emission Testing:

Emission testing plays a crucial role in assessing the environmental impact of vehicles and ensuring compliance with regulatory standards. It helps evaluate the performance of exhaust after-treatment systems and identifies any potential shortcomings in terms of emissions control. EN 52325 sets out specific testing procedures for different pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC), and particulate matter (PM). These tests involve driving cycles that simulate real-world driving conditions, enabling accurate measurement of emissions under various operating conditions.

EN ISO 3936:2018 provides guidelines for measuring exhaust emissions from motorcycles and mopeds using the Constant Volume Sampling (CVS) method. The CVS method is a widely accepted method for determining emission levels, and EN ISO 3936:2018 provides a standardized procedure for conducting these tests. By setting uniform guidelines for emission testing, EN 52325 and EN ISO 3936:2018 promote consistency and comparability across different vehicle models and manufacturers, ensuring that all vehicles meet the same environmental standards.

Conclusion:

In conclusion, emission testing is an essential aspect of vehicle performance that helps ensure that vehicles meet stringent environmental requirements and comply with regulations regarding air quality and noise pollution. EN 52325 and EN ISO 3936:2018 provide guidelines for conducting emission tests, including testing procedures for different pollutants and the use of the Constant Volume Sampling (CVS) method. By setting uniform guidelines for emission testing, these standards promote consistency and comparability across different vehicle models and manufacturers, ensuring that all vehicles meet the same environmental standards.
