USP Plastics Testing
USP Class Testing determines the biological response to elastomerics, plastics and other polymeric materials. Six Plastic Classes are based on responses to a series of In Vivo tests relating to the intended end-use of the plastic articles. Test article extracts are taken in normal saline, alcohol solution, polyethylene gycol, and/or sesame oil. Testing may be conducted in either GLP or non-GLP conditions.
