ASTM D 2794 - 93 (Reapproved 2010) Standard Test Method for Resistance of Organic Coatings to the Effects of Rapid Deformation (Impact)

American Society for Testing and Materials (ASTM). Current edition approved Dec. 1, 2010. Published December 2010. Originally approved in 1969. Last previous edition approved in 2004 as D2794 – 93 (2004). 3 p. This test method covers a procedure for rapidly deforming by impact a coating film and its substrate and for evaluating the effect of such deformation.
This test method should be restricted to testing in only one laboratory when numerical values are used because of the poor reproducibility of the method. Interlaboratory agreement is improved when ranking is used in place of numerical values.
