ISO 6101-2-2019 橡胶--原子吸收光谱测定法测定金属的含量--第2部分:铅含量的测定 Rubber — Determination of metal content by atomic absorption spectrometry — Part 2: Determination of lead content 

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-additions method might lower the bottom limit of detection.rd edition 2019-11 Rubber — Determination of metal content by atomic absorption spectrometry — Part 2: Determination of lead content Caoutchouc — Détermination de la teneur en métal par spectrométrie d'absorption atomique — Partie 2: Dosage du plomb Reference number ISO 6101-2:2019(E) ？ ISO 2019 ISO 6101-2:2019(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2019
