BS EN 15355:2008+A1:2010 Railway applications. Braking. Distributor valves and distributor-isolating devices

BS EN 15355 specifies requirements for the design, testing and quality assurance of distributor valves and distributor-isolating devices.

It applies to distributor valves and distributor-isolating devices, of graduated release type. Direct release types are not covered.

Functionally they are regarded as not containing relay valves of any type, even if the relay valves are physically an integral part of the distributor valves.

BS EN 15355 applies to both distributor-isolating devices mounted separate from the distributor valve and distributor-isolating devices integral with the distributor valve.

For interoperable freight wagons, these devices which are operated by compressed air according to BS EN 14198 are assessed according to the respective technical specification of interoperability.
