Abstract

This specification covers polysulfone resin (poly(oxy-p-phenylenesulfonyl-p-phenyleneoxy-p-phenyleneisopropylidene-p-phenylene)) for medical applications. Requirements and associated test methods for a form of this thermoplastic intended for use in manufacturing medical devices or components of medical devices are provided. The use of this resin in medical devices should be restricted to nonimplant applications until biocompatibility evaluations appropriate for the intended applications are successfully completed. The molecular weight of the resin shall be determined by osmotic pressure in monochlorobenzene. The polysulfone resin shall yield an infrared transmittance spectrum that exhibits major transmittance bands only at the same wavelengths as that of a reference spectrum. Medical devices made of polysulfone may be repeatedly sterilized through steam, ethylene oxide, irradiation, and dry heat sterilization, among others. The polysulfone resin shall be tested for nonvolatile content and melt flow, and shall conform to the specified electrical, physical and mechanical, and thermal properties.

Scope

1.1 This specification covers polysulfone resin (poly(oxy-1,4-phenylenesulfonyl-1,4phenylene (dimethylmethylene)-1,4phenylene)) as defined in ISO 251371, supplied by a vendor in virgin form (pellets, powder, fabricated forms and so forth) for medical applications. This specification provides requirements and associated test methods for this thermoplastic when it is intended for use in manufacturing medical devices or components of medical devices.

1.2 As with any material, some characteristics may be altered by the processing techniques (such as molding, extrusion, machining, sterilization, and so forth) required for the production of a specific part or device. Therefore, properties of fabricated forms of this resin should be evaluated using test methods which are appropriate to ensure safety and efficacy as agreed upon by the vendor, purchaser, and regulating bodies.

1.3 The standard allows for designation of polysulfone resin for all medical applications. The actual extent of performance and suitability for a specific application must be evaluated by the vendor, purchaser, and regulating bodies.

1.4 The properties included in this specification are those applicable for unfilled polysulfone (PSU) polymers with the addition of colorants and processing aids. Indicated properties are for injection molded forms. Forms containing fillers or other additives, as well as polymer blends which contain PSU, or reclaimed materials, are not covered by this specification.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 When evaluating material in accordance with this specification, hazardous materials, operations, and equipment may be involved. This standard does not purport to address all of the 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.
