Standard Practice for Evaluating the Water Wash-Off Resistance of Traffic Paints

Standard Details

1.1 A newly applied traffic paint film may be exposed to hard rain shortly after application. This practice was designed to simulate that condition and covers determination of the water wash-off resistance of an applied traffic paint film under controlled conditions. This test can be used to compare conventional and fast-dry traffic paints and the binders used in them for their relative ability to withstand heavy rain soon after application on roadway surfaces.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
