Match levels show how close each correspondence is. A means the object and the test or classification method both match, so the two documents are usually interchangeable for procurement. B and C are probable matches that must be checked clause by clause. D means only the general ICS category matches, so the documents address different subjects. E means no equivalent was found. A cross-reference is a research aid, not a legal equivalence.
