1. Scope 1.1 This specification covers melt processable molding and extrusion materials of PFA-fluorocarbon resin. The materials are copolymers of TFE-fluorocarbon resins containing perfluoroalkoxy side chains. 1.2 The tests involved are intended to provide information for identifying the materials covered. It is not the function of this specification to provide engineering data for design purposes. Specimens prepared by injection molding or extrusion could yield test results that may vary from the values in this specification. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 The following precautionary caveat pertains only to the test methods portions, Sections 7 and 8, of this specification: This standard does not purport to address all of the safety problems, 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.
