(Specification)Standard Specification for EFEP-Fluoropolymer Molding and Extrusion Materials
Standard Specification for EFEP-Fluoropolymer Molding and Extrusion Materials
ABSTRACT
This specification addresses the physical properties of melt processible molding and extrusion materials of EFEP-fluoropolymer, wherein the EFEP resin is a copolymer of ethylene, tetrafluoroethylene, and hexafluoropropylene. It does not cover blended and recycled materials. Covered here are two types of fluoropolymer that is supplied in pellet form and classified according to their melting points, while the resins of each type are divided into one to two grades in accordance with their melt flow rates. The materials shall be sampled in accordance with an adequate statistical sampling procedure and shall conform to specific gravity, melting point, melt flow rate, elongation, tensile strength, and dielectric constant and dissipation factor requirements when tested by the procedures itemized herein.
SCOPE
1.1 This specification covers melt processible molding and extrusion materials of EFEP-fluoropolymer. The EFEP resin is a copolymer of ethylene, tetrafluoroethylene, and hexafluoropropylene.
1.2 This specification does not cover blended materials and does not cover recycled materials.
1.3 The values stated in SI units as detailed in IEEE/ASTM SI-10 are to be regarded as the standard. The values given in parentheses are for information only.
1.4 The following safety hazards caveat pertains only to the test method 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: Although this specification and ISO 20568-1 and ISO 20568-2 differ in approach or detail, data obtained using either are technically equivalent.
1.5 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.
