USP-FDA Shared History and Mission. Eventually the answers depend on where you are required to clear a device.

USP Class testing is one of the most common methods of testing to determine bio-compatibility of materials.
. A list of the FDA-recognized consensus standards and test methods included in the ASCA Pilot for biocompatibility testing of medical devices. There are six classes VI being the most rigorous. Plastics were assigned Class I-VI based on the biological in vivo testing systemic injection intra-cutaneous and implantation tests.
Some medical silicones must meet USP Class VI FDA CFR 21 1772600 and RoHS requirements. USP class VI is also a good starting point. To begin the USA food and Drug Administration FDA places regulations on three different types of food additives- direct secondary direct and indirect food additives.
For filters composed primarily of plastic parts the relevant portion of the USP monograph is Chapter 88 Biological Reactivity Tests In Vivo Classification of Plastics Class 1 to VI. There may be some confusion between FDA USP Class VI and FDA food grade materials. The program specifications for the FDA.
Typical applications for our FDA NSF 51 USDA materials are disposable medical. Pharmacopoeia USP Class VI outlines requirements for system toxicity and intracutaneous toxicity for these cleaner compounds. RoHS a European Union Directive restricts the use of certain substances but manufacturers also need to know whether all the ingredients in a medical silicone are made of compliant materials.
Absorbable Polyhydroxybutyrate Surgical Suture Produced by Recombinant DNA Technology. Specially formulated for long term sealing. The testing consists of three parts intravenous systemic injection intracutaneous test and implantation test.
Class VI materials which were discussed earlier are tested according to the above protocols. USP and FDA maintain official contact through a number of established channels. Sil 714001 USP class VI Silicone 1 70 Yes transl.
USP Class Testing standards are determined by the United States. FDA food-grade rubber materials typically comply with FDA 21. That being said if you cant get an ISO 10993 compliant material often because the material simply hasnt been tested using a USP Class VI material is a less risky option.
How USP and FDA Work Together. 1965 USP XVII introduced Biological TestsPlastics Containers section was added and made official in the Compendium. USP Class VI Testing is only one standard of biocompatibility however.
By adhering to the standards of the USP and the FDA Class VI O-rings are much better suited for use in these industries for both the continued efficient operation of the plant and for the safety of the consumer or user of the products that are being made. However its acceptability applicability is declining while ISO 10993 becomes the gold standard. In 1988 in vitro tests were explored and USP concluded that in vitro.
USP Class VI Testing is only one standard of biocompatibility however. Moulded O-rings class 1 less than 10 furnace black These can be produced in all possible dimensions up to diameter 1400 mm internal. Table 1 shows our standard programme FDA compliant com-pounds which can be produced in a few days.
One standard often overlooked but usually published alongside USP Class VI is FDA 21 CFR 1772600. The USP Class VI compounds must be made from ingredients with clear histories of biocompatibility that meet tighter requirements for leachates. USP Class VI materials EPDM Silicone Fluorocarbon and Perfluoroelastomer 24 materials which are compliant to FDA 21 CF R1772600.
The USP-FDA relationship dates back to the 1906 Pure Food and Drug Act which deemed the United States Pharmacopeia and the National Formulary official compendia under federal law. USP Class VI Chapter 88 relates to in vivo biological reactivity tests its purpose is to determine the biological response impact of elastomeric materials on live animals. Guidance for Industry and FDA Staff Class II Special Controls Guidance Document.
The FDA requires testing of finished devices however the demonstration of biocompatibility of materials according to USP Class VI standards is provided as an aid to device manufacturers in their material selection process. Materials that meet USP Class VI standards generally ensure a high quality level and better acceptance with the FDA and USDA because the materials are believed to substantially reduce the risk of causing harm to patients from reaction to a toxic material. The FDA requirements differ from the TGAs.
While it is possible a USP Class VI material could also be ISO 10993 compliant its not a given and USP Class VI alone is not sufficient for adherence to ISO 10993. It generally ensures a high quality level and better acceptance with the FDA and USDA. Sil 714002 USP class VI Silicone 1 70 Yes transl.
Class VI testing is aimed to certify that there are no harmful reactions or long-term bodily effects caused by chemicals that leach out of plastic materials. Most importantly use of Class VI certified materials substantially reduces the risk of causing harm or increased stress to a patient from reaction to a toxic material. It consists of 3 testing requirements.
USP Class VI and FDA White List Silicone and Organic Elastomer Compounds for. Sample of the compound is prepared with specific extraction fluids like vegetable oil and polyethylene glycol. Both ISO 10993 and USP Class VI define testing requirements for biocompatibility the ability of a material to perform a desired function without causing adverse effects on.
