USP Class VI demands an intracutaneous irritation test. Predictable Safe and Stable. 3D printing of dental and orthopedic surgical guides.

USP Class VI. Typically the terms USP Class VI or ISO 10993 materials are used. Though not a limited series of tests some biocompatibility requirements for medical devices may exceed the testing performed in USP Class VI.

For this reason the FDA provides a standard 21 CFR1772600 defining allowable rubber compound ingredients and extractibles based on toxicity and carcinogenicity. Many medical device companies are familiar with USP Class VI but that standard isnt as strict as ISO 10993. Depending on the devices application and how the cable components will interact with the patient this higher level testing may not be needed.

Duration similar to ISO-10993 and each class has a different set of testing requirements. To begin let us address just what biocompatibility is. This is their current stance today.

USP Class VI testing is conducted by producing an extract of the product with different extraction fluids such as polyethylene glycol and vegetable oil and injecting it in specimen rabbits and mice in vivo alive to observe the biological response to the extract.
