18、s Specific to This Standard:3.1.1 fabricated forms, nthose items into which the virgin forms may be converted. These include shapes and forms producedby means of machining, extruding, and compression molding virgin forms into a subsequent entity (for example, fibers, tubes, rods,slabs, sheets, film,

19、 or complex shaped parts and devices).3.1.2 formulated compound, nmaterials, parts, or devices fabricated from virgin forms in such a way as to contain intentionalor unintentional adjuvant substances.3.1.3 virgin forms, nthe initially delivered form of the polymer as synthesized from its monomers pr

20、ior to any processing orfabrication into a medical device. The provided resin is typically in the form of pellets, granules, or powder and is the materialfrom which fibers, tubes, rods, slabs, sheets, films, or specific parts and devices are fabricated.4. Classification4.1 The PEEK polymer in the sc

21、ope of this specification is a pure semicrystalline homopolymer consisting of phenylene ringsconnected by ether (E) and carbonyl (or ketone, K) groups along the polymer chain (see Appendix X1). Its polymeric structureis defined by the repeating unit EEK.4.2 Types of PEEK plastics, molding, and extru

22、sion grades are described in Classification System D4000.5. Properties5.1 The properties listed below shall be considered in selecting material(s) in accordance with the specific end-use requirements.5.2 The infrared spectrum5 of these materials is characteristic of their molecular repeating units.

23、A representative spectrum islisted in Appendix X3. The PEEK polymer shall yield an infrared spectrum, which exhibits major bands only at the wavelengthslisted for a standard reference spectrum of that material.5.2.1 The infrared spectrum, as used in this specification, is to identify the specific ty

24、pe of poly aryl ether ketone (PAEK) presentand does not necessarily indicate an acceptable degree of material purity.5.2.2 The presence of additional bands in the samples infrared spectrum compared to that of the reference material may indicatea different PAEK or impurities, or both.5.3 The physical

26、cation of Organic Compounds, 5th ed., John Wiley polyetheretherketoneAPPENDIXES(Nonmandatory Information)X1. RATIONALEX1.1 The PEEK polymers may be processed by most techniques available for thermoplastic polymers. Medical devices andcomponents of medical devices made of PEEK polymers may be sterili

27、zed. Sterilization methods successfully used include steam,ethylene oxide, and irradiation. Repeated sterilization may weaken parts fabricated of any plastic material. The number of timesa given part may be sterilized safely without fear of subsequent failure depends on a number of factors including

28、 the molecularweight of the polymer and design, fabrication, intended function, and method of sterilization of the device. Therefore, it isimperative that the manufacturer test the device in order to determine the maximum number of sterilization cycles to which it canbe safely subjected.X1.2 The pot

29、ential to develop a significant level of crystallinity is an important characteristic of these materials. Performancecharacteristics are related to the percent crystallinity. Certain additives and processes (for example, excessive cross linking) canlimit these materials ability to crystallize. There

30、fore, this feature of the polymer and its fabricated form should be evaluated, usingappropriate test methods, to ensure efficacy.X1.3 A formulated compound or fabricated part or device may contain optional adjuvant substances required for the fabricationor intended use of the end product. The biocom

31、patibility of these adjuvant substances, and subsequent formulated compounds,parts, and devices shall be established in accordance with Practice F748 or the ISO 10993 series.X2.
