Matching is by reference, ignoring case and spacing, and it tries the undated form too: typing EN 60204-1 finds every dated edition on the lists. "Not on the lists" means the reference is not in any summary list we archive today (Machinery, Radio Equipment, General Product Safety) nor in the CRA and AI Act drafting programmes; it says nothing about other directives.
