本文件规定了一种使用柔性电池从表面提取酸溶性污染物进行分析的方法，该电池采用粘合剂贴片或套筒的形式，可以附着在任何表面上，无论其形状（平面或曲线）及其方向（朝任何方向，包括向下）。所述方法适合在现场使用，以在涂漆或类似处理之前确定酸溶性污染物的存在。本文件不包括已溶解污染物的后续分析。适用于现场使用的分析方法见ISO 8502的其他部分，如ISO 8502-5.本文件的程序与ISO 8502-6相似，但不等同于ISO 8502-6。主要区别在于所使用的溶剂和可对萃取溶液进行的后续分析。

This document specifies a method of extracting, for analysis, acid soluble contaminants from a surface by use of flexible cells in the form of adhesive patches or sleeves which can be attached to any surface, regardless of its shape (flat or curved) and its orientation (facing in any direction, including downwards).The described method is suitable for use in the field to determine the presence of acid soluble contaminants before painting or a similar treatment.This document does not cover the subsequent analysis of the contaminants that have been dissolved off. Methods of analysis suitable for field use are described in other parts of ISO 8502 such as ISO 8502-5.This document is similar in procedure to, but not equal to, ISO 8502-6. The main difference is the solvent used and the subsequent analysis that can be performed on the extraction solution.
