Standard Specification for Polysulfone Resin for Medical Applications
STANDARD published on 1.12.2018
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

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.
