What is EN ISO 22241-4:2013

EN ISO 22241-4:2013 refers to a technical standard that sets guidelines and requirements for the handling, storage, and distribution of urea solutions used in selective catalytic reduction (SCR) systems to reduce emissions from diesel engines. SCR technology is widely used to comply with stringent emission regulations in automotive and industrial applications.

Understanding Urea Solutions and SCR Systems

Urea solutions, commonly known as diesel exhaust fluid (DEF) or AdBlue, are employed in SCR systems as a reducing agent. When injected into the exhaust stream, urea converts harmful nitrogen oxides (NOx) emissions into harmless nitrogen gas (N2) and water vapor (O). This process occurs in the SCR catalytic converter, which contains a special catalyst and helps to achieve up to 90% NOx reduction.

The use of urea solutions and SCR systems has become essential in meeting strict emission standards worldwide. By applying this technology, pollutants released from diesel engines are significantly reduced, contributing to improved air quality and public health.

The Importance of EN ISO 22241-4:2013

EN ISO 22241-4:2013 plays a crucial role in ensuring the proper handling, storage, and distribution of urea solutions for SCR systems. Compliance with this standard guarantees that the entire supply chain, from production to end-user, follows specific measures to maintain the quality and integrity of the urea solution. The standard covers aspects such as material compatibility, container labeling, sampling procedures, and contamination prevention.

Without adherence to EN ISO 22241-4:2013, there is a risk of product degradation, reduced efficiency of the SCR system, and potential harm to the environment. This standard provides guidance to manufacturers, distributors, and end-users to ensure the effective implementation of SCR technology and maintain the desired emission reduction efficiency.

Conclusion

EN ISO 22241-4:2013 is a technical standard designed to regulate the handling, storage, and distribution of urea solutions used in SCR systems. With the ever-increasing focus on reducing emissions from diesel engines, compliance with this standard becomes essential for ensuring the proper functioning and effectiveness of SCR technology. By following the guidelines set by EN ISO 22241-4:2013, stakeholders in the supply chain can contribute to cleaner air and a healthier environment.
