Vinyl siding certified through VSI's Program may also include colors that have been certified to meet or exceed the color retention requirements of ASTM D6864 or D7251 through VSI's Program . In addition to meeting the performance characteristics for weatherability, windload, and impact resistance covered under ASTM D3679, these products will resist major color changes in a variety of climates, based on two-year outdoor weathering studies.
