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

Summary

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 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 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 with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Note 1: Although this classification system and ISO?20568-1 and ISO?20568-2 differ in approach or detail, data obtained using either are technically equivalent.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.


Rationale:

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. The classification of ECTFE materials into groups in accordance with their physical appearance, and further into classes based on melt flow rate, is provided. The test specimens shall be subjected to tests to determine their melt flow rate, melting endotherm peak, specific gravity, tensile property, dielectric constant and dissipation factor, and oxygen index.
