This part of GB/T 16886 specifies strategies for hazard identification and tests on medical devices for the following biological aspects:
——genotoxicity;
——carcinogenicity;
——reproductive and developmental toxicity.
This part of GB/T 16886 is applicable for evaluation of a medical device whose potential for genotoxicity, carcinogenicity or reproductive toxicity has been identified.
Note: guidance on selection of tests is provided in GB/T 16886.1/ISO 10993-1.

3 Terms and Definitions
For the purposes of this document, the terms and definitions given in GB/T 16886.1, GB/T 16886.12 and the following apply.
3.1
carcinogenicity test
test to determine the tumorigenic potential of medical devices, materials and/or extracts using either single or multiple exposures over a major portion of the life span of the test animal
Note: these tests may be designed to examine both chronic toxicity and tumorigenicity in a single experimental study. When chronic toxicity and carcinogenicity are evaluated within a single study, care in study design with emphasis on dose selection should be exercised. This will help to ensure that premature mortality from chronic/cumulative toxicity does not compromise the statistical evaluation of animals that survive until scheduled study termination (i.e. normal life-span).
