ASTM D6777 Relative Rigidity Testing for Poly Vinyl Chloride (PVC) Siding
ASTM D6777 test method determines the properties of vinyl siding panels by measuring their relative rigidity or stiffness. This relative rigidity is controlled by the configuration of vinyl siding. The vinyl sidings with high relative rigidity are easier to grip and have a straightening effect.
