Rubber. Determination of metal content by atomic absorption spectrometry - Determination of lead content1 Scope This document specifies an atomic absorption spectrometric method for the determination of the lead content of rubbers. The method is applicable to raw rubber and rubber products. There is no limit to the concentration of lead that can be determined. High or low concentrations can be determined, provided that suitable adjustments are made to the mass of the test portion and or the concentration of the solutions used. The use of the standard
