1.1 This specification covers poly(ether ketone ketone) materials, commonly referred to as PEKK, which are suitable for injection molding, 3D printing, additive manufacturing, powder coating and extrusion. This classification system provides requirements for the use of regrind or reprocessed materials.
1.2 This specification covers thermoplastic resin materials supplied in pellet as well as powder form.
1.3 This specification applies only to PEKK copolymers, without any additional fillers or inorganic additives, alloys or treatments for modification of attributes.
1.4 This classification system and subsequent line callout (specification) are intended to provide means of calling out poly(ether ketone ketone) materials used in the fabrication of end items or parts.
1.5 Poly(ether ketone ketone) (PEKK) is a member of the poly (aryl ether ketone) or PAEK polymer family. PEKK has a broad range of monomer combinations of Isophthaloyl and Terephthaloyl moeities. This standard classifies the polymer options.
1.6 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 1: PEKK is a thermoplastic polymer. Testing conditions can affect the technical results. Specimens prepared by techniques different than prescribed in this specification can have properties that vary from the values specified.
1.7 The values stated in SI units, as detailed in IEEE/ASTM S-10, are to be regarded as the standard. The values given in parentheses are for information only.
