Question: Could you explain, what exactly is the difference betweensecurity door in Security Class 2 and 3?
Security testing of security doors according to European directive ENV 1628 includes also a manual attempt to get through the door in a determined time, using an exactly defined tools. Of course, the higher the class, the more improved the tools and longer time. The most important difference between Classes 2 and 3 is: Tools in Class 2 don´t include the most „important“ tool – a lever. The door is not tested to be opened with a lever. And the statistics state that the most „frequent“ way of breaking in is using a lever. The Security Class 3 doors are tested and have to be resistant against using this tool. And the time resistance is almost double. So we definitely recommend security doors in Class 3.
