BS EN 16657 specifies the minimum performance and construction requirements for overfill prevention controllers located on the tank vehicle.
BS EN 16657 applies to overfill prevention controllers for liquid fuels, having a flashpoint up to but not exceeding 100 °C.
The requirements apply to overfill prevention controllers suitable for use at ambient temperatures in the range from -25 °C to +60 °C, and are subject to normal operating pressure variations.
BS EN 16657 on transport tank equipment for overfill prevention devices for static tanks is useful for:
Dangerous goods need to be packaged so that they can withstand the shocks while transportation or loading.
Overfill prevention devices are intended to be used in/with underground or above ground, non-pressurized, static tanks designed for liquid fuels. These overfill prevention controllers monitor the level sensor and interrupt the filling process as soon as any critical situation is reached.
BS EN 16657 provides guidance on performance and construction requirements for overfill prevention controllers, which helps you ensure the efficient performance of prevention controllers mounted on the tank vehicle.
Compliance with BS EN 16657 allows you to ensure that the product flow is stopped when the sensor detects “non-permissive” signal to prevent overfill. It also allows you to construct controllers suitable for safe operations at the power supply of tank vehicles.
BS EN 16657 provides guidance on test and assessment methods, marking and labeling for the overfill controllers, to help you ensure that the controller is durable, efficient and the process considers environmental aspects.
