ASTM D 8655 : 2026

1.1This classification covers rigid Poly(Vinyl Chloride)(PVC), Chlorinated Poly(Vinyl Chloride)(CPVC), copolymers, blends and alloys, and composite materials derived from recyclate from extruded, molded or calendared forms or operations and composed of polyvinyl chloride, chlorinated polyvinyl chloride, polyvinyl chloride copolymers, or blends and alloys containing polyvinyl chloride and the typical ingredients found in these compound materials. The recycled material classifications inform users regarding additive ingredient compatibility, formulation knowledge potential process contamination, form of material, regulated substances and contaminants, collectively to aid in determining the applicability for an end use. This standard is not intended to apply to collected materials incoming to a recycling facility but rather to that material leaving the recycling/reprocessing facility. Fig. X1.1 in Appendix X1 provides a flow chart depicting the system boundaries.

1.2This classification does not apply to nonrigid PVC and nonrigid CPVC recycled materials or content.

1.3The requirements in this classification are intended as a representation and possible specification of recycled content compounds used to manufacture finished products. These attributes are based on a combination of declarations and evidence related to material sourcing. These attributes do not necessarily reflect the final attributes of the finished products. See the applicable ASTM standards for requirements pertaining to the finished products.

1.4The text of this classification consists of standard references, notes, and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this specification.

1.5Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
