All interested parties are welcome to join in the standards developing activities of ASTM International Committee D20 on Plastics. Current D20 projects such as the development of proposed new standards covering backed vinyl siding and bioreactor landfill conditions demonstrate the diversity of D20’s work., Backed Vinyl Siding, Subcommittee D20.24 on Plastic Building Products is developing WK18425 , Specification for Rigid Poly (Vinyl Chloride) (PVC) Siding with Foam Plastic Backing (Backed Vinyl Siding). Vinyl siding with an integral foam plastic backing has been commercially available for nearly a decade. Because backed-vinyl siding is a variation of the basic siding product, testing and third party certification for…, Biodegradability of Plastics in Landfill Conditions, A proposed new standard being developed by Subcommittee D20.96 on Environmentally Degradable Plastics and Biobased Products will aid in the determination of degradation and biodegradation of plastics in landfill environments. All interested parties are encouraged to participate in the development of WK18427 , Determining the Aerobic Degradation and Anaerobic Biodegration of Plastic Materials…
