Description / Abstract:

1. Scope

1.1 This classification covers segmented block copolyether-ester elastomers suitable for molding and extrusion. This classification allows for the use of segmented block copolyether-ester elastomers that are recycled, reconstituted, recycled-regrind, recovered, or reprocessed, or a combination thereof, provided that the requirements as stated in this classification are met. It is the responsibility of the supplier and the buyer of recycled, reconstituted, recycled-regrind, recovered, or reprocessed, or a combination thereof, copolyether-ester elastomers 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 using the suffixes as given in Section 5.

1.3 This classification system and subsequent line callout (specification) 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 plastic field 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 following precautionary caveat pertains only to the test methods 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 system is similar to ISO FDIS 14910-1/-2 1997, although the technical content is significantly different.

NOTE 2--This classification system is being revised to add international specimens and test procedures as the standard for compliance. The previous test specimens and Tables TEEE and A are included in Appendix X1 as a reference for those wishing to use them. It is recommended that the material manufacturer be consulted on all callouts against this classification system.
