What is BS EN 16452 - Railway braking blocks about?
BS EN 16452 is the European standard on railway applications that discusses railway braking blocks for the smooth run of the vehicle.
BS EN 16452 gives the requirements for the design, dimensions, performance, and testing of
a brake block (otherwise known as brake shoe insert) that acts on the wheel tread as part of a tread brake system and is applicable to brake blocks of either “K”, “L”, or “LL” friction level designed to be fitted to tread braked rail vehicles.
NOTE: BS EN 16452 does not cover cast iron brake block requirements.
Who is BS EN 16452 - Railway braking blocks for?
BS EN 16452 on railways applications is applicable to:
- Manufacturers of railway brake blocks
- Railway engineer
- Mechanical engineer
Why should you use BS EN 16452 - Railway braking blocks?
A brake block is a stator part of a tread brake adapted to generate a friction force when engaged with a wheel tread.
BS EN 16452 provides the overall requirements and operational criteria of the railway brake block.
Brake block performance requirements are mentioned in BS EN 16452 to provide an evaluation of the capability of the brake block to operate under the duty level.
General requirements for conducting dynamometer test programmes are described in BS EN 16452.
BS EN 16452 navigates you through the test procedures of brake block with the rail vehicle in order to confirm that it satisfies the basic safety and technical interchangeability requirements.
Overall, BS EN 16452 could assist you design and manufacturing railway braking blocks that help in minimising braking shocks by its smoother action and permitting higher load factor ensuring product quality, reliability and conformity and considering health and environmental needs.
