American Society for Testing and Materials (ASTM). Current edition approved Nov. 1, 2005. Published December 2005. Originally approved in 1995. Last previous edition approved in 2002 as B 860 - 02. 3 p. This specification covers zinc master alloys which are used in hot dip galvanizing for the purpose of adjusting the concentration of certain alloying elements in the molten zinc bath. Table 1 covers the chemical composition of these materials which include four master alloys of zinc-aluminum (brightener) and one master alloy of zinc-antimony.
