Bibliography

The scope of this part is: - to establish a working terminology for crossings with moveable parts, which means crossings with moveable parts to close the gap of the running edge, and their constituent parts, and identify the main types; - to list the minimum informative requirements for the manufacture of crossings with moveable parts and/or their constituent parts; - to formulate codes of practice for inspection and tolerances for crossings with moveable parts and/or their constituent parts; - to establish the limits and extent of supply; - to list the method by which crossings with moveable parts and their constructional parts should be identified and traced; - to list the different and varying ways by which crossings with moveable parts can be described, using the following parameters: - geometry of crossings; - types of construction; - performance requirements; - design criteria; - tolerances and inspection.
