【国外标准】 Standard Specification for Ultra-High-Molecular-Weight Polyethylene (UHMW-PE) Solid Plastic Shapes

This specification focuses on the classification, and requirements and test methods for the material and properties of solid plastic shapes manufactured from ultra-high-molecular-weight polyethylene (UHMW-PE), both virgin and recycled. The properties included in this specification are those required for the compositions covered and are derived from molded samples or fabricated from sheet, rod and profiles. The mechanical properties for which the materials shall be tested on and shall accordingly adhere to are elongation stress, elongation at break, and Izod impact strength.1.1 This specification covers requirements and test methods for the material and properties of solid plastic shapes manufactured from UHMW-PE.1.2 The properties included in this specification are those required for the compositions covered and are derived from molded samples or fabricated from sheet, rod and profiles. Requirements necessary to identify particular characteristics important to specialized applications are described by using the classification system given in Section 4.1.3 This specification allows for the use of recycled plastics (as defined in Guide D5033).1.4 The values are stated in SI units and are to be regarded as the standard in all property tables. For reference purposes, English units are also included in Table S-UHMW-PE and Table A and are not necessarily exact equivalents.1.5 The following precautionary caveat pertains only to the test method portions 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 requirements prior to use.NOTE 1: There is no known ISO equivalent to this standard.
