What does the NEC Code say about ground rod electrode diameters?

Diameters must be 0.625 inches minimum and the rod length must be 96 inches (8 feet) minimum. Any rod less than 0.625 inches DOES NOT meet the NEC Code, unless it is “listed.” Galvan has achieved this compliance!

What I don't understand is the compliance with "equivalent to Stainless steel or nonferrous rods."

Who decided a galvanized rod is equivalent and if it is what type of rod would not be equivalent?
