本文件给出了用于评估多孔无机材料清洁方法的危害性和有效性的试验方法。不包括壁画和多色画。 评估包括使用现场分析和/或实验室研究。 为了防止过度清洁，对潜在危害的评估比有效性更为重要。重要的是，清洁始终处于被视为有效的最低水平，并尊重原始表面和饰面。过度清洁是一个术语，用于表示不必要的材料移除造成了不可逆转的损害，这些材料是物体价值的一部分。 本文件适用于: a） a部分:所有清洁方法，具有参数化和再现性的特点（见EN 17138）。 b） b部分:所有正在开发的新方法。 本文件适用于评估最佳清洗方法和所选清洗工艺参数的优化。

This document gives the test methodology for evaluation of both harmfulness and effectiveness of a cleaning method as applied to porous inorganic materials. Mural paintings and polychromy are excluded. Evaluation includes the use of on-site analyses and/or laboratory studies. The evaluation of the potential harm has a higher priority than the effectiveness in order to prevent overcleaning. It is important that cleaning is always at the minimum level deemed effective and that it respects the original surface and finishes. Overcleaning is a term used to indicate that irreversible damage has been done by the unnecessary removal of materials, which are part of the value of the object. This document applies to: a) Part A: all methods of cleaning, which have characteristics of parameterization and reproducibility (see EN 17138). b) Part B: all new methods that are under development. This document applies to evaluate the optimum methods for cleaning and the optimization of the parameters of the selected cleaning process.
