Rubber. Dissolution by acid digestion Ingestion-build-117251 BS EN 1570 specifies the1 Scope This International Standard specifies methods for disintegration of raw rubber and 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).
