ASTM D6905

Standard Practice for Impact Flexibility of Organic Coatings

Organization: ASTM
Publication Date: 1 December 2020
Status: active
Page Count: 4
ICS Code (Organic coatings): 25.220.60
scope:

This practice covers a procedure for determining the ability of a coating film and its substrate to resist shattering, cracking, or chipping when the film and substrate are distended beyond their original form by impact.

This practice does not measure impact resistance but uses rapid impact to improve Test Methods D522, a test method for flexibility. Since the impact of the coating is almost instantaneous, all of the problems associated with time variables in the mandrel tests are eliminated.

This practice is similar in content but not technically equivalent to Test Method D2794.

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

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.

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.
