ASTM D6864-03ae1

Standard Specification for Color and Appearance Retention of Solid Colored Plastic Siding Products

ABSTRACT
This specification focuses on the requirements and test methods for the color and appearance retention of solid colored plastic siding products. Color retention testing provides a method for estimating the acceptability of color change in a siding product over a period of years of service. Calculation of ellipsoid values for indicating compliance with this specification are provided.
SCOPE
1.1 This specification establishes requirements and test methods for the color and appearance retention of solid colored plastic siding products.
1.2 Color retention testing provides a method for estimating the acceptability of color change in a siding product over a period of years of service.
1.3 Methods of indicating compliance with this specification are provided.
