METHODS OF TEST FOR PAINTS AND VARNISHES: PART F17: DETERMINATION OF WET-SCRUB RESISTANCE AND CLEANABILITY OF COATINGS (ISO 11998:1998, MOD)
The ability of coatings to withstand wear caused by repeated cleaning operations and to resist
permanent blemishing by stains is an important consideration both from a practical point of
view and when comparing and rating such coatings. This Malaysian Standard specifies an
accelerated method for the determination of wet-scrub resistance. With regard to the
cleanability of coatings, only the method is specified and not the soiling agents.
NOTE. Since these properties depend not only on the quality of a coating but also on the substrate, the method of
application, the drying conditions and other factors, the results obtained are not directly transferable to actual
practice. In this standard the evaluation of the coating is based on a defined substrate, a fixed application method,
specified drying conditions and a defined method of wet scrubbing.
