What is BS EN ISO 15380:2012

The BS EN ISO 15380:2012 is an international standard that focuses on the cleanliness of hydraulic fluid power systems. It provides guidelines and specifications for assessing the level of particulate contamination in hydraulic systems, aiming to ensure their proper functioning and longevity. This technical article aims to provide an in-depth understanding of BS EN ISO 15380:2012 and its significance in maintaining the cleanliness of hydraulic systems.

Standard Requirements

One of the key requirements outlined in BS EN ISO 15380:2012 is the establishment of contamination control practices. It emphasizes the importance of proactive measures to prevent particulate contamination during the manufacturing, installation, and maintenance of hydraulic systems. These practices include using clean components, minimizing contamination sources, employing effective filtration systems, and implementing regular system monitoring.

The standard also sets specific cleanliness levels that hydraulic systems should meet. These cleanliness levels are defined by the maximum allowable size and concentration of particles in the hydraulic fluid. Ensuring compliance with these cleanliness levels is crucial in preventing system failures, reducing downtime, and prolonging the lifespan of hydraulic components.

Benefits of Compliance

Adhering to the guidelines outlined in BS EN ISO 15380:2012 brings several benefits to hydraulic system operators and equipment manufacturers. Firstly, it improves the overall performance and reliability of hydraulic systems by reducing fluid contamination. Cleaner hydraulic fluids result in better lubrication, which enhances system efficiency and reduces wear on components.

Secondly, compliance with this standard helps mitigate the risk of unexpected system failures due to contaminated fluids. Maintaining a high level of cleanliness reduces the likelihood of blockages, valve malfunctions, and premature component wear, thereby increasing system uptime and productivity.

BS EN ISO 15380:2012 also promotes environmental sustainability by minimizing fluid waste. Implementing effective contamination control practices reduces the frequency of hydraulic fluid changes, resulting in cost savings and reduced environmental impact.


BS EN ISO 15380:2012 plays a vital role in ensuring the cleanliness and optimal performance of hydraulic systems. By providing guidelines for contamination control practices and establishing cleanliness levels, this international standard helps prevent failures, prolong component lifespan, and reduce downtime. Compliance with BS EN ISO 15380:2012 not only enhances system reliability but also contributes to cost savings and environmental sustainability. It is essential for hydraulic system operators and equipment manufacturers to familiarize themselves with this standard and incorporate its requirements into their practices.
