適用范圍
This International Standard specifies methods for disintegration of raw rubber and rubber products by nitric acidor by a mixture of nitric and sulfuric acids. This International Standard is generally applicable, but is essentialwhere 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 byvolatilization.These methods will be used in order to produce solutions for the determination of metals, for example as traces,if the application of ISO247 is not advisable. These methods prevent loss of volatile metal derivatives and theformation of insoluble metal silicates (which may result during dry ashing of halogenated rubbers containingzinc or of rubbers filled with silica).
