    Which method is there to verify copper usage time

    A: This is too general!

    1. What is the status of this copper?

    2. What equipment is this copper used for?

    3. What is the use environment of this copper equipment?

    Only more specific, you can use the experimental method to obtain the data, otherwise it can only be guessed out of thin air!
