Scope

1.1 This classification covers acetal materials suitable for molding and extrusion. This specification allows for the use of acetal plastic materials that are recycled, reconstituted, recycled-regrind, recovered, or reprocessed, or combination thereof, provided that the requirements as stated in this specification are met. It is the responsibility of the supplier and the buyer of recycled, reconstituted, recycled-regrind, recovered, or reprocessed acetal plastic materials, or combination thereof, to ensure compliance. (See Guide D 5033). 1.2 The properties included in this classification are those required to identify the compositions covered. There may be other requirements necessary to identify particular characteristics important to specialized applications. These may be specified by using the suffixes as given in Section 5. 1.3 This classification and subsequent line callout are intended to provide a means of calling out plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection should be made by those having expertise in the field of plastics design after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the costs involved, and the inherent properties of the material other than those covered by this classification. 1.4 The values stated in SI units are to be regarded as the standard. 1.5 The following precautionary caveat pertains only to the test method portion, Section 11, of this classification. 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 1—This classification is similar to ISO 9988-1 and 9988-2, although the technical content is significantly different. NOTE 2—This classification was revised in 1992 to include international 4-mm specimens and test procedures as the standard for compliance. The 3.2-mm specimens, test methods, and Tables POM, A, and B that were superceded by the revision are included in Appendix X2, as a reference for those wishing to use them. It is recommended that the material manufacturer be consulted on all callouts against this classification.
