Over deze norm
1.1 These test methods cover a procedure for determining the resistance of wall paints to erosion caused by scrubbing, referred to herein after as “scrub resistance.”
1.2 Two test methods are covered as follows:
1.2.1 Test Method A—Cycles-to-failure obtained on test paint.
1.2.2 Test Method B—Ratio expressed as a percentage of cycles-to-failure obtained on the test paint to that obtained on a concurrent run with a known reference paint.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
