This specification designates woods to be used as panels in weathering tests of coatings such as solvent-borne or water-borne paints. Different wood species shall be considered for testing due to their wide variations in the anatomy and density. Wood species materials for test panels include western red cedar, white pine and Ponderosa pine, southern pine, redwood, and Douglas fir. Wood panel characteristics such as weight per volume, wood character, panel thickness, surface smoothness, relative humidity, and growth rings density shall be in accordance with the specification.

1.1 This specification designates woods for weathering tests of exterior solvent-borne or water-borne paints and other materials of similar purpose. Such tests may include either outdoor exposure tests or accelerated laboratory tests. It is the purpose of this specification to minimize the influence of variation of wood of a given species on test results.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
