ISO 5398-4:2007描述了皮革水溶液中铬的测定方法。这是对皮革中总铬的分析；它不是特定于化合物或特定于其氧化状态。本方法描述了通过电感耦合等离子体-光发射光谱法测定铬，适用于氧化铬含量超过1 mg/kg的皮革。包括两种制备待分析溶液的技术。如有争议，应使用湿式氧化技术。

ISO 5398-4:2007 describes a method for the determination of chromium in aqueous solution obtained from leather. This is an analysis for total chromium in leather; it is not compound specific or specific to its oxidation state.This method describes the determination of chromium by inductively coupled plasma – optical emission spectrometry and is applicable to leathers which are expected to have chromic oxide contents in excess of 1 mg/kg. Two techniques for the preparation of the solution to be analysed are included. In the case of dispute, the wet oxidation technique is to be used.
