The method serves for the determination of siliceous impurities, together with the silica endogenous to the plant. It cancels and replaces ISO Recommendation R 763-1971, of which it constitutes a technical revision. It consists in incinerating of a test portion at 525 C, and separating of the mineral matter insoluble in dilute hydrochloric acid solution. The method for the determination of mineral impurities, generally originating from the soil, is described in ISO 762.
