Scope:

1.1 This test method is designed to evaluate the effectiveness of water-repellent compositions for retarding dimensional changes in coated wood submerged in water. It can also be used to measure the differential swelling of untreated wood when exposed to liquid water environments. The compositions tested are designed to be mixed until uniform and applied by brush, roller, dip or spray to an exterior wood surface.

1.2 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.
