ASTM-D2793 › Standard Test Method for Block Resistance of Organic Coatings on Wood Panel Substrates
The following bibliographic material is provided to assist you with your purchasing decision:
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
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.
