Determination of metal content by atomic absorption spectrometry - Determination of zinc content1 Scope This document specifies an atomic absorption spectrometric method for the determination of the zinc content of rubbers. The method is applicable to raw rubber and rubber products having zinc contents at a minimum of 0,05 % (mass fraction). Zinc contents below this limit can be determined, provided that suitable adjustments are made to the mass of the test portion and or to the concentrations of the solutions used.
