There are several classes of USP class VI being the highest grade and suitable for implantation in the human body with a test temperature of 121C.

. USP Class VI requires the most testing of the six USP class plastic groups. USP Class VI refers to one of the six designations for plastics from General Chapter of the United States Pharmacopeia and National Formulary USP-NF. 62 Systemic injection in mice intracutaneous injection and intramuscular implantation in rabbits are recommended by the USP guidelines for Class VI tests.

This chapter provides guidelines for testing and certification of a material to be used within a medical device. USP Reference Standards are used to demonstrate identity strength purity and quality for medicines dietary supplements and food ingredients. Extract of sample in NaCl Systemic Injection Test in mouse intravenous Extract of sample in NaCl Intracutaneous Test in rabbit.

USP Class Testing standards are determined by the United States. While class plastics tests have some value in a biocompatibility testing program a full Class VI test is rarely needed for a medical device. USP Class VI Plastic Tests are designed to evaluate the biological reactivity of various types of plastics materials in vivo.

USP Class VI tests and the guidelines have no alternative nonanimal methods. Chapter 88 sets out standards for testing and certification of a material to be utilised in a medical device. In 1988 in vitro tests were explored and USP concluded that in vitro assays could serve as a decision point as to whether or not a sample would be tested in animals.

The USP is a non-government organisation and is mainly concerned with pharmaceutical and bio-technology industries and in order to adhere to these standards set by the organisation all O-rings. Certificates of Analysis COAs report the test results for a specific batch of materials. There are six classes VI being the most rigorous.

Extract of sample in NaCl Systemic Injection Test in mouse intravenous Extract of. Certificates of Conformance COC attest to a batchs. Measures toxicity and irritation when a sample of the compound is administered orally applied to the skin and inhaled.

Developed to test drug containers the class plastics tests are frequently done on unmolded plastic resins as well as containers. USP Class VI applies to one of the six classifications for plastics from General Chapter 88 of the United States Pharmacopeia and National Formulary USP-NF. Request a Quote Now.

Passing the test means the material is not toxic and does not leach potentially harmful substances into fluids or tissue. In particular regarding the USP class VI certification process materials have to pass the biological tests ie. USP regularly tests the standards you use to ensure that they remain up-to-date and suitable for your compendial needs.

USP Class VI refers to a set of biocompatibility testing requirements from the US. USP Class Plastics Tests USP CLASS VI To test medical device biocompatibility manufacturers often use USP procedures such as the USP In Vivo Biological Reactivity Tests Class I-VI Plastics Tests. Tests are based on material extracts that according to the thermal resistance of the materials are made after contacts and at one of the following temperatures 50 C 70 C and 121.

Pharmacopoeia Class VI judges the suitability of plastic material intended for use as containers or accessories for parenteral preparations. Acute Systemic Toxicity Systemic Injection Test. The following tests are needed for USP Class VI plastic certification.

Cyclic Olefins Polyamide 6 Polycarbonate Polyethylene to include both HDPE and LDPE PET and PETG Poly Ethylene-Vinyl Acetate Polypropylene Polyvinyl Chloride Polyvinyl Chloride Plasticize. USP Class testing is one of the most common methods of testing to determine bio-compatibility of materials. The following tests are needed for USP Class VI plastic certification.

The Class Plastics tests consist of various combinations of the USP Intracutaneous Test and the USP Systemic Injection Test using one or more combinations of four extracting media. Professional Plastics General Product Range Brochure. Specifically USP publishes test instructions for the plastics polymers and elastomers that are used in medical devices and surgical equipment.

USP Class VI requires the most testing of the six USP class plastic groups. 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. Pharmacopeia USP a non-profit organization whose standards inform decision-making at the US.

In order to identify the biocompatibility of materials USP Class VI testing is required. To test medical device biocompatibility manufacturers often use USP procedures such as the USP in vivo biological reactivity tests Class IVI plastics tests. As one of the most widely used methods VI forms part of six different classes with this being the most thorough.

The USP testing expands the plastic types to include specific test requirements for the following plastic types. USP Class VI Testing involves three in vivo biological reactivity evaluations generally performed on mice or rabbits to mimic use in humans. Suitability under USP Class VI is typically a base requirement for medical device manufacturers.

Food and Drug Administration FDA. Specialty Silicone Products SSP provides complete certifications to demonstrate the quality of its SSP-2390 Series USP Class VI FDA and RoHS compliant silicones. Class VI testing has the most stringent criteria and involves 3 tests that evaluate reactions for toxicity in tissue.

The species and number of animals used in this study were recommended by the USP guidelines. The in vivo tests USP 88 are designed to determine the biological response of animals to elastomeric plastics and other polymeric material with direct or indirect patient contact or by the injection of specific extracts prepared from the material under test. Three tests are described ie the Agar Diffusion Test the of 1212 equipped with a thermometer a pressure Direct Contact Test and the Elution Test1 The decision as to gauge a vent cock a rack adequate to accommodate the which type of test or the number of tests to be performed test containers above the water level and a water cooling.

Certified USP Class VI Silicones. This form of testing is designed to certify that no harmful reactions or long-term issues are caused to the body by chemicals that are released or leached from plastic materials. Plastics were assigned Class I-VI based on the biological in vivo testing systemic injection intra-cutaneous and implantation tests.

The Table 1 classification facilitates communication among suppliers users and man-ufacturers of plastics by summarizing the tests to be per-formed for containers for injections and medical devices if a The following tests are designed to determine the biologi-need for classification exists.
