Significado e uso
5.1 Os revestimentos arquitetônicos de interiores costumam ficar descoloridos pela poeira e outros materiais sujos. The test method covers the relative ease and completeness of removing specific dirt from such surfaces by scrubbing. The greater the ease of removing dirt with minimal membrane erosion, the longer the expected service life.

5.2 The results obtained by this test method are not necessarily relevant to all types of stains.

5.3 Semi-finish paints usually only require the use of non-abrasive cleaners to remove dirt well, while flat paints may require abrasive types.
