Abstract Combining with the testing cases of electric fans, how to correctly understand
the requirements of the protection against access to live parts, mechanical hazards,
mechanical strength, creepage distances and electric clearances in the standards is
analyzed.The differences of relevant provisions in the previous and new standards and
error-prone situations are concluded, which can provide reference for applying relative
safety standards accurately.
