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.
