Omfattning
This International Standard specifies methods for disintegration of raw rubber och rubber products by nitric acid or by a mixture of nitric and sulfuric acids. This International Standard is generally applicable, but is essential where potentially volatile elements or combinations of elements are present (i.e. As, Sb, Bi, and Zn + Cl, Cu + Cl and Pb + Cl). It is useful in these cases because lower temperatures are involved which result in less loss by volatilization.
These methods will be used in order to produce solutions for the determination of metals, for example as traces, if the application of ISO 247 is not advisable. These methods prevent loss of volatile metal derivatives or the formation of insoluble metal silicates (which may result during dry ashing of halogenated rubbers containing zinc or of rubbers filled with silica).
