Scope

1.1  This specification is intended to be a means of calling out finished machined parts ready for general use. 1.2  This specification establishes requirements for parts machined from polychlorotrifluoroethylene (PCTFE) semifinished parts. 1.3  For aerospace grade, machined PCTFE parts, use Specification D7194 . Note 1:  Quick-quenched PCTFE will potentially exhibit dimensional relaxation in the vicinity of T g  = 55°C (131°F). Note 2:  Although no recommendations are made regarding the limiting upper use temperature of PCTFE, the heat deflection temperature of PCTFE as determined by Test Method D648 is 126°C (259°F). 1.4  The values stated in SI units are to be regarded as standard. The values in parentheses are for information only. 1.5  The following precautionary caveat pertains only to the test methods 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 3:  There is no known ISO equivalent to this standard. 1.6  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.
