Scope
This document specifies the technical requirements for recycled polymethyl methacrylate cast sheets (also known as "recycled organic glass sheets"), describes the testing methods for recycled organic glass sheets, and stipulates the inspection rules, marking and labeling, accompanying documents, packaging, transportation, and storage. This document applies to cast recycled organic glass sheets produced with fully or partially mixed recycled methyl methacrylate as raw materials (referring to methyl methacrylate homopolymer sheets, or copolymer sheets of methyl methacrylate and acrylate monomers/methyl methacrylate monomers), with methyl methacrylate, initiators, plasticizers, and other main raw and auxiliary materials, as well as other monomers, plasticizers, and crosslinking agents. Sometimes, other additives such as colorants, mold release agents, and UV absorbers are also added as needed. This document does not apply to polymethyl methacrylate recycled plastics from hazardous waste such as medical waste and pesticide packaging, or radioactive waste.
