This specification covers the testing and requirements of extruded and compression molded polytetrafluoroethylene (PTFE) rods and heavy-walled tubing manufactured from virgin or reprocessed PTFE resin. Covered here are three types of PTFE fluorocarbon materials as follows: Type I (premium), materials having maximum physical and electrical properties to meet rigid requirements; Type II (general purpose), materials having properties required of general electrical, mechanical, and chemical applications; and Type III, materials for noncritical chemical, electrical, and mechanical applications. These types are further subdivided into two grades, and even further into four classes as appropriate. Sampled specimens shall be appropriately tested on the following: workmanship and appearance (color, finish, and internal defects); specific gravity; tensile strength and elongation; dielectric strength; dimensional stability; and melting point.
Keywords:
fluorocarbon polymer, fluoropolymers, granular PTFE, polytetrafluoroethylene, PTFE, PTFE heavy-walled tubing, PTFE rod,, ICS Number Code 83.140.99 (Other rubber and plastic products)
1. Scope | ||||||||||||||||||||||||||||||
1.1?This specification covers extruded polytetrafluoroethylene (PTFE) rod, heavy-walled tubing, and basic shapes manufactured from the PTFE resin of Specification D4894 and reprocessed PTFE resin (as defined in Guide D7209). 1.2?The specification covers all sizes of rod, tubing, and basic shapes with a wall thickness of 1.6 mm (1/16?in.) or greater. These materials must be made wholly from PTFE and produced in accordance with good commercial ram extrusion practices. Note 1:?This specification and ISO/DIS 13000-1 (1997) and
ISO/DIS 13000-2 (1997) differ in approach, however, data obtained
using either are technically equivalent.
Note 2:?For compression molded PTFE materials, see
Specification D3294. Material
that can be certified to Specification D3294 may be substituted for
Specification D1710, however
the reverse in not true.
1.3?The values stated in SI units, as detailed in IEEE/ASTM SI 10 are to be regarded as the standard. The inch-pound units given in parentheses are provided for information only. 1.4?The following precautionary caveat pertains to the test methods portion, Section 12, only 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. 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. |
