意义和目的
4.1 油漆经常被弄脏, 尤其是靠近门口的地方, 视窗, 以及工作和游乐区. These test methods cover the determination of the relative resistance of different paints to erosion upon repeated scrubbing during the life of the paint.

4.2 Test Method D4213 is a similar scrubbing resistance test that uses weight-loss techniques and reports volumetric film erosion rates.

4.3 Test Method A measures scrubbing resistance through the traditional cyclic failure concept. Poor correlation in the scrubbing test can be attributed to variations in bristle stiffness, washability tester condition, 应用, 和干燥条件. Test method B has been developed to improve reproducibility.
