Standard Test Method for
Scrub Resistance of Paints by Abrasion Weight Loss1

This standard is issued under the fixed designation D 4213; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This test method covers an accelerated procedure for
determining the resistance of paints to erosion caused by
scrubbing. (Note: The term wet abrasion is sometimes used for
scrubbing, and wet abrasion resistance or scrub ability for
scrub resistance.) Although scrub resistance tests are intended
primarily for interior coatings, they are sometimes used with
exterior coatings as an additional measure of film performance.

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

1.3 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.
