1、Designation: D3275 08 (Reapproved 2013)D3275 18Standard Classification System forE-CTFE-Fluoroplastic Molding, Extrusion, and CoatingMaterials1This standard is issued under the fixed designation D3275; the number immediately following the designation indicates the year oforiginal adoption or, in the
2、 case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope Scop
3、e*1.1 This classification system covers melt processible molding, extrusion, and coating materials of ethylene-chlorotrifluoroethylene (E-CTFE) fluoroplastics. The resin is a copolymer of ethylene and chlorotrifluoroethylene containingapproximately 80 weight % of chlorotrifluoroethylene.1.2 The valu
4、es stated in SI units, as detailed in IEEE/ASTM SI-10, are to be regarded as standard.1.3 The following precautionary statement pertains only to the test methods portion, Section 11 of this classification system.This standard does not purport to address all of the safety concerns, if any, associated
5、 with its use. It is the responsibility of theuser of this standard to establish appropriate safety safety, health, and healthenvironmental practices and determine theapplicability of regulatory limitations prior to use.NOTE 1Although this classification system and ISO 12086-1ISO 20568-1 and ISO 120
6、86-2ISO 20568-2 differ in approach or detail, data obtainedusing either are technically equivalent.1.4 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Principles for the Development of International S
