Historical Standard: ASTM D2793-99 Standard Test Method for Block Resistance of Organic Coatings on Wood Panel Substrates
SUPERSEDED (see Active link, below)
ASTM D2793
1. Scope
1.1 This test method covers the determination of the block resistance of organic coatings on wood and wood-based panel substrates. 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.
1.2 General methods for determining block resistance are outlined in 6.2 and 6.3. Variations inherent in user materials and procedures, however, may dictate adjustments to the general method to improve accuracy. Paragraphs 6.4 and 6.5 provide guidelines for tailoring the general procedure to a user's specific application. Paragraph 6.6 offers a rating methodology.
1.3 Test Method D2091 should be used for the determination of print resistance or pressure mottling of organic coatings, particularly lacquers, applied to wood-based case goods such as furniture.
1.4 This standard does not purport to address all of the safety problems, 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.
