NFPA 58 Piping Gasket Materials

In section 6.9.3.5.5 of NFPA 58, is the requirement for a 1500F melting point for the metal material only or also the material confined within the metal of a gasket. We are considering a spiral wound gasket for flanged joints, propane piping, the metal (stainless steel) meets the criteria, but the filler material may not (unless we change to a more expensive gasket where both the metal and filler both meet the 1500 F melt point rating).
