1、Designation:D567513(Reapproved 2018)Standard Classification forLow Molecular Weight PTFE and FEP Micronized Powders1This standard is issued under the fixed designation D5675;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of
2、 last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This classification system provides a method of ad-equately identifying low molecular weight polytetrafluoroeth-ylene(PTFE
3、)and fluorinated ethylene propylene(FEP)mi-cronized powders using a system consistent with that ofClassification System D4000.It further provides a means forspecifying these materials by the use of a simple line calloutdesignation.This classification covers fluoropolymer micron-ized powders that are
4、 used as lubricants and as additives toother materials in order to improve lubricity or to control othercharacteristics of the base material.1.2 These powders are sometimes known as lubricant pow-ders.The powders usually have a much smaller particle sizethan those used for molding or extrusion,and t
5、hey generallyare not processed alone.The test methods and propertiesincluded are those required to identify and specify the varioustypes of fluoropolymer micronized powders.Recycled fluo-ropolymer materials meeting the detailed requirements of thisclassification are included(see Guide D7209).1.3 The
6、se fluoropolymer micronized powders and the ma-terials designated as filler powders(F)in ISO 12086-1 andISO 12086-2 are equivalent.21.4 The values stated in SI units as detailed in IEEE/ASTMSI-10 are to be regarded as the standard.1.5 This standard does not purport to address all of thesafety concer
7、ns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.Specific precautionary statements are given in 7.1.2.1.6 This internation
8、al standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.
