【国外标准】 Standard Specification for Polyethylene Plastics Molding and Extrusion Materials from Recycled Post-Consumer (HDPE) Sources (Withdrawn 2016)

This specification provides for the identification of polyethylene plastics molding and extrusion materials from recycled post-consumer (HDPE) sources. This specification covers post-consumer HDPE materials from the following: (1) blow molded household chemical containers, (2) blow molded milk, juice, and water containers, (3) materials from the spunbonded process, (4) thermoformed packaged food containers and personal care packages, (5) injection molded packaged food containers and beverage bottle base cups, and (6) injection molded housewares and industrial articles such as pails, crates, totes, and pallets. The melt index, nominal density, tensile strength, and secant modulus of elasticity in bending shall be tested to meet the requirements prescribed.1.1 This specification provides for the identification of recycled post-consumer HDPE molding and extrusion materials, from specified sources, in pellet or chip form so that the supplier and the user can agree on the acceptability of lots or shipments. This specification covers post-consumer HDPE materials from the following: (1) blow molded household chemical containers, (2) blow molded milk, juice, and water containers, (3) materials from the spunbonded process, (4) thermoformed packaged food containers and personal care packages, (5) injection molded packaged food containers and beverage bottle base cups, and (6) injection molded housewares and industrial articles such as pails, crates, totes, and pallets. Other post-consumer HDPE materials may be added to this specification when such material streams are characterized.1.1.1 The tests described in this specification are intended to provide information for identifying these materials. The separation by sources improves the usefulness of the materials.1.1.2 It is not the function of this specification to provide specific data for design purposes.1.2 This specification provides a procedure to certify that the materials are from post-consumer sources.1.3 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.1.4 The following precautionary caveat pertains only to the test method portion, Section 10, of this specification: This 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 and health practices and determine the applicability of regulatory limitations prior to use.Note 1There are no ISO standards covering the primary subject matter of this specification.
