ASTM D3275-00

Standard Classification for E-CTFE-Fluoroplastic Molding, Extrusion, and Coating Materials

SCOPE
1.1 This classification covers melt processible molding, extrusion, and coating materials of ethylene-chlorotrifluoroethylene (E-CTFE) fluoroplastics. The resin is a copolymer of ethylene and chlorotrifluoroethylene containing approximately 80 weight % of chlorotrifluoroethylene.
1.2 The values stated in SI units, as detailed in IEEE/ASTM SI 10, are to be regarded as the standard.
1.3 The following precautionary statement pertains only to the test methods 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--Although this specification and ISO 12086-1 (1995) and ISO 12086-2 (1995) differ in approach or detail, data obtained using either are technically equivalent.
