Physical property test includes size measurement, mechanical property tests, durability tests, and so on. Size measurement is the measurement of length, outer diameter, wall thickness and other dimensions, mechanical properties including medical device flow, connection strength, particle contamination, tip penetration force, syringe (needle) rigidity, connection firmness, syringe (needle) tough-ness, body closure, cone-head closure separation force, sliding performance, etc, durability testing is the evaluation of the performance of the medical device in the process of long-term use, including packaging integrity, Dye penetration, sealing strength, creep test, swelling test, etc.

The chemical performance test is to analyze and test the composition and chemical properties of medical devices. It mainly includes reducing substances, heavy metal content, acidity and alkalinity, evaporation residue, ultraviolet absorbance of extraction solution, ethylene oxide residue, purified water quality testing, and so on.

Microbiological testing is to test the medical device products and the environment. It mainly includes the colony number, microbial limit, product initial contamination bacteria, BI sterilization effect, sterility, bacterial endotoxin detection, and other aspects.
