Analyze the influencing factors of key components
Path 1
b. Frequency and intensity of use
Post market data from the products or similar products(Failure rate/Compliant rate...)
g. if any more.? ..
Evaluation path selectionPath 1 or Path 2 ?
f. Component maintenance and repair status
Conduct accelerated aging tests on products/key components
e. Packaging and sterilization
end
d. cleaning and disinfection
Decompose into subsystem/component evaluation
Path 2
a. Key componnets malfunction
Formulate an evaluation report
Conduct product verification directly
Start of usefullife evaluation
Analysis
usefullife timepre-define
influencing factors
Conduct real-time/accelerated aging tests
