ASTM-D6763 › Standard Guide for Testing Exterior Wood Stains and Clear Water Repellents
The following bibliographic material is provided to assist you with your purchasing decision:
This guide covers the selection and use of procedures for testing exterior wood stains. This includes both water borne and solvent borne semitransparent and opaque stains. The different conditions that affect coatings are presented in details. The balance of properties must be considered when establishing the requirements and selecting the tests. The different test methods in determining the liquid coating properties are enumerated and discussed. The different methods in determining the coating application and film formation are presented and discussed in details. The different test methods of determining the appearance of dry films are presented. The different test method of determining the dry coating properties are presented in details. The different test methods and practices in performing the chemical analysis of exterior woods are presented in details. Although many of the recommended test methods attempt to simulate conditions under which coatings are applied and used, it is not possible to duplicate accurately all possible conditions. Testing materials, including appropriate controls, under field conditions is recommended for the final evaluation of suitability.
Scope
1.1 This guide covers the selection and use of procedures for testing exterior wood stains. This includes both water borne and solvent borne semitransparent and opaque stains. The properties that can be examined or, in some cases, the relevant test procedures are listed in 2.1 and 2.2.
Note 1—The term "opaque stain" is defined as a pigmented composition intended for use on wooden surfaces to produce a uniform finish that obscures the grain and color of the wood, but not its surface texture; also called solid color or solid hide.
Note 2—The term "semitransparent" is defined as a pigmented composition intended for use on wooden surfaces to produce a uniform finish that does not fully obscure the grain or the texture of the wood.
1.1.1 Discussion—When applied to woods that differ in color, there is a color difference between stained substrates.
1.2 This standard may involve hazardous materials, operations, and equipment. 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 requirements prior to use.
