The first three (Grade AA, Grade A, Grade B) are for ground profile hobs, and the fourth one (Grade D) is for unground profile hobs.
BS 2062-1 provides you with illustrations to get a clear picture of general hob terminology. BS 2062-1 discusses tooth form, dimensions, bore, hubs, gashes, as well as keys and keyways for the specified gear hobs.
