1.1 This classification system provides a method of adequately identifying PTFE micropowders using a system consistent with that of Classification System D 4000. It further provides a means for specifying these materials by the use of a simple line callout designation. This classification covers fluoropolymer micropowders that are used as lubricants and as additives to other materials in order to improve lubricity or to control other characteristics of the base material. 1.2 These powders are sometimes known as lubricant powders. The powders usually have a much smaller particle size than those used for molding or extrusion, and they generally are not processed alone. The test methods and properties included are those required to identify and specify the various types of fluoropolymer micropowders. Recycled fluoropolymer materials meeting the detailed requirements of this classification are included (see Guide D 5033). 1.3 These micropowders and the materials designated as filler powders (F) in ISO 12086-1 and ISO 12086-2 are equivalent. 1.4 The values stated in SI units as detailed in IEEE/ASTM SI 10 are to be regarded as standard. 1.5 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. Specific precautionary statements are given in 7.1.2. |
