1.1 This part of ISO xxxxx establishes a system of designation for polyetheretherketone (PEEK)
moulding and extrusion materials which may be used as the basis for specifications.
Polyetheretherketone polymer chains are composed of phenylene rings linked in (1,4) position by a
sequence of two ether groups followed by one ketone group.
1.2 The grades of PEEK plastics are differentiated from each other by a classification system based on
appropriate levels of the designatory properties
a) melt viscosity or melt volume-flow rate,
b) tensile modulus,
c) tensile strength
and on information about the intended application and/or method of processing, important properties,
additives, colorants, fillers and reinforcing materials.
1.3 The designation system is applicable to all polyetheretherketones.
It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or
modified by colourants, fillers, reinforcements or other additives.
1.4 It is not intended to imply that materials having the same designation give necessarily the same
performance. This part of ISO xxxxx does not provide engineering data, performance data or data on
processing conditions which may be required to specify a material for a particular application and/or
method of processing.
If such additional properties are required, they shall be determined in accordance with the test methods
specified in ISO xxxxx-2, if suitable.
1.5 In order to specify a thermoplastic material for a particular application or to ensure reproducible
processing, additional requirements may be given in data block 5.
