BS EN ISO 17075-2:2017规定了测定皮革浸出溶液中铬（VI）的方法 在规定的条件下。所描述的方法适用于定量分析样品中的铬（VI）含量 皮革含量降至3毫克/千克。本文件适用于所有皮革类型。从该方法获得的结果严格取决于提取条件。后果 通过使用其他提取程序（提取溶液、pH值、提取时间等）获得的 与本文件所述程序产生的结果相当。如果皮革样品同时使用ISO 17075-1和本文件进行测试，则使用本文件获得的结果 文件被视为参考文件。本文所述方法的优点是 提取物的颜色没有干扰。然而，实验室间试验确实如此 未显示出显著差异（见附录D），两种方法的结果具有可比性。交叉引用:ISO 2418ISO 3696ISO 4044:2017ISO 4684购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS EN ISO 17075-2:2017 specifies a method for determining chromium(VI) in solutions leached from leather under defined conditions. The method described is suitable to quantify the chromium(VI) content in leathers down to 3 mg/kg.This document is applicable to all leather types.The results obtained from this method are strictly dependent on the extraction conditions. Results obtained by using other extraction procedures (extraction solution, pH, extraction time, etc.) are not comparable with the results produced by the procedure described in this document.If a leather sample is tested with both ISO 17075-1 and this document, the results obtained with this document are considered as the reference. The advantage of the method described in this document is that there are no interferences from the colour of the extract. Nevertheless, interlaboratory trials do not show significant differences (see Annex D) and the results are comparable between both methods.Cross References:ISO 2418ISO 3696ISO 4044:2017ISO 4684All current amendments available at time of purchase are included with the purchase of this document.
