ASTM D 2793 - 99 (Reapproved 2005) Standard Test Method for Block Resistance of Organic Coatings on Wood Panel Substrates

American Society for Testing and Materials (ASTM). Current edition approved May 15, 2005. Published June 2005. Originally approved in 1969. Last previous edition approved in 1999 as D 2793 – 99. 3 p.

Block resistance is the ability of a coating to resist sticking to another surface and to resist any change in appearance when it is pressed against that surface for a prolonged period of time.
