1. Scope *
1.1 This specification covers liquid crystal polymeric materials suitable for injection molding and extrusion. This specification allows the use of recycled, reconstituted, recycled-regrind, recovered, or reprocessed liquid crystal polymer, 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 liquid crystal polymer, or combination thereof, to ensure compliance.
1.2 The properties included in this specification are those required to identify the compositions covered. There may be other requirements necessary to identify particular characteristics important to specialized applications. These shall be agreed upon between the user and the supplier, by using suffixes as given in Section 5.
1.3 This specification is intended to be a means of calling out plastic materials used in the fabrication of end-use items or parts. It is not intended for the selection of materials. Material selection should be made by those having expertise in the plastics 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 specification.
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 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 1--There are no ISO standards covering the primary subject matter of this specification.
