ASTM D2065-03

Standard Test Method for Determination of Edge Performance of Composite Wood Products Under Surfactant Accelerated Moisture Stress

SIGNIFICANCE AND USE
This test method provides a measure of the dimensional stability and integrity of the coated edge of various composite wood products under accelerated moisture stress. It is widely used as an indicator or predictor of the anticipated performance of composite wood products during exterior exposure. It may be used for developmental evaluation of coatings, substrates, or both. It may also be useful for quality control or monitoring of the production of coated or uncoated composite wood products.
SCOPE
1.1 This test method is intended to serve as a means for measurement of swelling and cracking of the coated or uncoated edge of a composite wood substrate that has been subjected to wetting by a test solution containing surface active agent.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.
