usp class vi vs iso 10993
This post will take a deeper look at what biocompatibility is and how it is defined by the International Standards Organization. You might establish biocompatibility via making the device of a Recognized Consensus Standard material using a validated process that does not degrade that material or by ISO 10993 testing.
ISO-10993 is a standard that utilizes systemic toxicity and intracutaneous reactivity testing.
. 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.

If yes to the first question then USP Class VI is not a relevant qualification for it. It depends to a large extent on the application and therefore also on the application period of the finished product. A more rigorous standard for the biological evaluation of medical devices is ISO-10993.
Though not a limited series of tests some biocompatibility requirements for medical devices may exceed the testing performed in USP Class VI. There are six classes VI being the most rigorous. 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.
In 1995 the FDA adopted ISO 10993 as its biocompatibility approach. Most applications are fairly benign to elastomers. 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.
USP Class VI. The ISO 10993 set entails a series of standards for evaluating the biocompatibility of medical devices to manage biological risk. Unlike other rubber standards theres no one standard that engineers use for an approval.
ISO 10993 is designed for medical products that remain permanently or for a very long time in the human body so for shorter applications a USP Class VI or even a lower USP Class certification is often sufficient. USP Class testing is one of the most common methods of testing to determine bio-compatibility of materials.
