(Practice)Standard Practice for Evaluating the Efficiency of Chemical Removers for Organic Coatings
Standard Practice for Evaluating the Efficiency of Chemical Removers for Organic Coatings
SIGNIFICANCE AND USE
5.1 Old coatings, such as paint or related coatings, may have to be removed from a surface before successful recoating can occur. This practice can be used to test the coatings removal efficiency of products designed for such use.
SCOPE
1.1 The practice evaluates the effectiveness of coatings removers used on clear or pigmented coatings as applied to wood and metal.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 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.
