It classifies this hardware into different categories based on frequency of use, durability, security, and corrosion resistance. An important feature is the durability test, in which the door handles must withstand a high number of operations; in the highest user category, at least 200,000 operations are required. The products must also be able to offer specific properties such as maintenance-free operation.
