This test method covers the determination of silica in refuse-derived fuel (RDF), RDF ash, fly ash, bottom ash, or slag. The test method is an acid dehydration gravimetric procedure and is independent of interferences. Silicon compounds shall be dissolved by alkali fusion and dehydrated with hydrochloric acid (HCl). Dehydration is completed by ignition, and the silica is volatilized as silicon tetrafluoride.
