What defines a Class 3 leakage?

Class 3 leakage is defined as leakage that forms drops falling from the item checked. This classification indicates the most serious level of leakage where fluid is visibly dripping or pooling under the vehicle or equipment, which can pose a significant safety hazard and potential operational issues. The presence of drops not only suggests a failure of seals or fittings but also indicates that the amount of fluid is considerable enough to be a concern for loss of function or safety.

In the context of vehicle maintenance, understanding the severity of leaks is crucial for ensuring equipment reliability and safety. Class 3 leakage should prompt immediate attention, as it can affect vehicle operation and integrity.

The other classifications relate to different levels of leakage but do not represent the same level of concern as Class 3. Wetness alone may indicate minor leakage, discoloration may not necessarily mean that there is a material loss of fluid, and no visible leakage suggests everything is functioning as intended. However, the presence of drips means immediate action is needed to prevent further issues.
