ASTM D8033-22

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D8033 − 16 D8033 − 22
Standard Classification System for
Poly(Ether Ether Ketone) (PEEK) Molding and Extrusion
Materials
This standard is issued under the fixed designation D8033; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope Scope*
1.1 This classification system covers poly(ether ether ketone) materials suitable for injection molding and extrusion. This
classification system allows for the use of recycled materials provided that all specification requirements are met.
1.2 The properties included in this standard are those required to identify the compositions covered. Other requirements necessary
to identify particular characteristics important to specialized applications are to be specified by using the suffixes in Section 5.
1.3 This classification system and subsequent line callout (specification) are intended to provide means of calling out poly(ether
ether ketone) materials used in the fabrication of end items or parts. It is not intended for the selection of materials. It is
recommended that material selection be made by those having expertise in the plastics field only after careful consideration of the
design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be
employed, the cost involved, and the inherent properties of the material other than those covered by this specification.
1.4 Poly(ether ether ketone), commonly referred to as PEEK, is a member of the poly (aryl ether ketone) or PAEK family.
Specification D6262 covers properties of PAEK shapes and includes shapes produced from PEEK.
NOTE 1—There is no known ISO equivalent to this standard.This standard and ISO 23153 address the same subject matter, but differ in technical content.
1.5 The following precautionary caveat pertains only to the test method portion, Section 11, of this classification system: 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 safety, health, and healthenvironmental practices and determine the applicability
of regulatory limitations prior to use.
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.

4. Classification
4.1 Poly(ether ether ketone) materials are classified into groups that are subdivided into classes and grades as shown in the Basic
Property Table (Table PEEK).
NOTE 2—An example of a specification based on this classification system is given below. The specification PEEK012GF30 indicates the following:
PEEK = Poly(ether ether Ketone) as found in Terminology D1600
01 (Group) = General Purpose

D8033 − 22
2 (Class) = Low Flow
GF30 (Grade) = 30 % Glass-Filled, with corresponding requirements shown in Table PEEK.
4.1.1 To facilitate incorporation of future or special materials the “Other” category for group (00), class (0), and grade (0) is shown
in Table PEEK. The basic properties for these materials are obtained from Table A as they apply.
4.2 Table A shall be used to specify the physical property requirements that shall be shown by a six-character designation. The
designation shall consist of the letter A and the five digits comprising the cell numbers for the property requirements in the order
as they appear in Table A.
4.2.1 Reinforced filled and lubricated variations of the basic materials are identified by a single letter from Table 1 that indicates
the filler and/or reinforcement used and two digits that indicate the nominal quantity in percent by weight. A second letter, from
Table 1a, when desired, is used to indicate the form or structure of the reinforcement and/or filler, but is not used for functional
mixtures. Thus, the letter designation G for glass, E for beads or spheres or balls, and 33 for percent by weight, specifies a
reinforced or filled material with 33 percent by weight in the form of glass beads, spheres, or balls. The reinforcement letter
designations and associated tolerance levels are shown in Table 1. Form and structure letter designations are shown in Table 1a.
NOTE 3—This part of the classification system uses the percent of reinforcements or additives, or both, in the callout of the modified basic material. The
types and percentages of reinforcements and additives are often shown on the supplier’s technical data sheet unless they are proprietary in nature. If
necessary, additional callout of these reinforcement and additives is accomplished by use of the suffix part of the system (see Section 5).
4.2.2 Although the values listed in Table A are necessary to include the range of properties available in existing materials, this does
not imply that every possible combination of the properties exists or can be obtained.
4.2.3 When the grade of the basic material is not known, or is not important, the “0” grade shall be used for the reinforced
materials in this system.
NOTE 4—An example of the use of this classification system for specifying a special poly(ether ether ketone) plastics material is given as follows. The
specification PEEK0120GF30A43460 would have the following material requirements:
PEEK0120 = poly(ether ether ketone) from Table PEEK,
GF30 = glass reinforced at the 30 % nominal level,
A = Table A property requirements,
4 = tensile strength, 130 MPa min,
3 = flexural modulus, 4.5 GPa min,
4 = Notched Izod impact, 60 J/m min,
6 = deflection temperature, 275°C min, and
0 = unspecified.
If no properties are specified, the designation would be: PEEK0120GF30A00000.
