What is BS EN 15612 about?
BS EN 15612 is applicable to brake pipe accelerators designed to vent the brake pipe of railway vehicles when an emergency braking is initiated, without taking the type of vehicles and track-gauge into consideration.
BS EN 15612 specifies the requirements for the design, manufacture, and testing of brake pipe accelerators.
Who is BS EN 15612 for?
BS EN 15612 on railway brake pipe accelerator is useful for:
- Railway engineers
- Manufacturers of railway brakes
Why should you use BS EN 15612?
A brake pipe accelerator is a component connected to the brake pipe that, in response to a brake command, assists the propagation of the brake command throughout the train by locally venting the brake pipe. BS EN 15612 provides the design and manufacture of the brake pipe accelerators.
BS EN 15612 provides functional and operational requirements of brake pipe accelerators to ensure a continuing rapid fall to below 2,5 bar and to ensure the rapid increase in the brake cylinder pressure on every vehicle in the train set. All the environmental requirements and conditions are listed in BS EN 15612 within the design concept of the components. BS EN 15612 gives the type tests of a brake pipe accelerator including individual brake pipe accelerator tests and simulated train consist tests to check the accuracy and the measurement of uncertainty.
Overall, BS EN 15612 let you manufacture a railway brake pipe that helps in detecting the loss of vacuum when the pressure rises in the brake pipe and opens the pipe to the atmosphere on the vehicle in order to achieve uniform braking during an emergency.
