1. Scope | ||||||||||||||
1.1 This standard classification system and basis for specification covers polytetrafluoroethylene (PTFE) filled molding compounds made with virgin PTFE resins defined in Specification D4894, as Types II and III. Note 1: This system can be used as a model for other PTFE
compounds having particulate fillers that can survive the sintering
temperatures of PTFE as can those listed in this standard. This
system is restricted to virgin PTFE base resin for technical
reasons. Recycled or reprocessed material cannot be processed
successfully.
Note 2: The properties measured on commercially fabricated
parts may differ from the listed values for samples prepared by the
procedures given in this specification, depending on part geometry
and processing parameters.
1.2 The values stated in SI units are to be regarded as standard. 1.3 The following statement applies 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 and health practices and determine the applicability of regulatory limitations prior to use. Note 3: There is no known ISO equivalent to this standard. |
