ASTM D5824-98(2017)

Standard Test Method for Determining Resistance to Delamination of Adhesive Bonds in Overlay-Wood Core Laminates Exposed to Heat and Water

SIGNIFICANCE AND USE
4.1 This test method measures quantitatively the effects of water soaking and drying, and their associated swelling and shrinking stresses on adhesive bonds in overlay-laminated assemblies.  
4.2 Adhesive bond performance is based on the ability of the adhesive and adhesive bonds to resist delamination during accelerated exposure to water and heat.  
4.3 Resistance to delamination when subjected to environmental factors is critical to the performance of the laminated assembly in service.  
4.4 This test method is to be used to determine the quality of adhesive bonds in overlay-wood core laminates after the adhesive has been certified by a specification appropriate for the product, class, and end use.
SCOPE
1.1 This test method provides a procedure to determine the quality of bond between an overlay and a wood core in an adhesively bonded laminate. The quality of bond is determined by measuring the resistance to delamination of the adhesively bonded laminate when tested under specific conditions of preparation, conditioning, and testing. Such products include, but are not limited to, window and door components, such as stiles and rails, and other overlaid panels. Typical wood-based cores are finger-jointed lumber, particleboard, oriented strand board, and hardboard. Typical overlays would be veneer, high-pressure laminate, high-density polyethylene, and fiberglass-reinforced plastic.  
1.2 Adhesive bond performance as measured by resistance to delamination in this test method is suitable for use in adhesive product development, manufacturing quality control, and monitoring bonding processes.  
1.3 This test method does not provide guidance for determining bond line performance for plywood products.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 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.  
1.6 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.
