What is EN ISO 4615:2021?

EN ISO 4615:2021 is a technical standard that specifies the requirements and test methods for automotive petrol engine oils. It was published by the European Committee for Standardization (CEN) and has been adopted as an international standard by the International Organization for Standardization (ISO). This standard provides guidance for the formulation, labeling, and performance testing of engine oils used in gasoline engines.

Importance of EN ISO 4615:2021

EN ISO 4615:2021 is essential for ensuring the quality and performance of automotive petrol engine oils. It sets the benchmark for manufacturers to develop high-quality oils that meet the requirements of modern gasoline engines. By adhering to this standard, engine oil producers can provide lubricants that effectively protect engines from wear, reduce friction, and enhance fuel efficiency.

Moreover, EN ISO 4615:2021 helps consumers make informed choices when purchasing engine oil. With the standardized labeling and performance ratings specified in this standard, users can easily identify products that meet their vehicles' requirements and ensure optimum engine performance.

Key Requirements and Test Methods

The standard outlines various requirements for automotive petrol engine oils, including viscosity, volatility, flash point, and performance under different operating conditions. For example, it specifies the kinematic viscosity limits at different temperatures and shear rates to assess the oil's flow characteristics and resistance to thinning at high temperatures.

EN ISO 4615:2021 also includes test methods to evaluate the performance of engine oils, such as wear protection, deposit formation, and sludge control. These tests simulate real-world engine conditions and help determine whether the oil meets the necessary performance criteria.

Conclusion

EN ISO 4615:2021 plays a vital role in ensuring the quality, performance, and compatibility of automotive petrol engine oils. By following this standard, oil manufacturers can develop products that meet the stringent requirements of modern engines, while consumers can make informed choices based on standardized labeling and performance ratings.

Adherence to EN ISO 4615:2021 not only promotes better engine protection and performance but also contributes to environmental sustainability by improving fuel efficiency and reducing emissions. Therefore, this standard is essential for both industry professionals and vehicle owners who want to optimize the performance and longevity of automotive engines.
