Anotace textu normy ASTM D3275-18(2023) :

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.

Keywords:

chlorotrifluoroethylene copolymers, chlorotrifluoro- ethylene-ethylene copolymers, E-CTFE, extrusion material, fluoropolymer, fluoropolymers, melt flow, melt-processible fluoropolymer, molding material, powder coating, roto-lining , roto-molding,, ICS Number Code 83.080.20 (Thermoplastic materials)

Doplňující informace

1. Scope

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.
