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.
