What is meant by resistance classes 1 to 6?

Resistance classes classify the capacity to resist burglary. They define how resistant windows and doors are to attempted break-ins. The higher the class, the longer burglars need to force entry and the more likely it is that they require professional tools. These resistance classes are divided up according to the tools and work methods used in order to make a comparison on a European level and categorise such elements in line with EN1627-1630.
