Today, the protection of the personal property becomes ever more important. Burglary-resisting entry doors which can not be opened only by simple physical force (thus without the use of any tool) are very important to protect your property.
Depending on the mechanical resistance of constructional elements it is possible to classify them into 6 different resistance classes. The classification defines itself with regard to the probable operation of the burglar.

Resistance class	presumed function of the author
WK 1	The burglar tries to open the locked door by physical force (kicking at the door, throwing himself against the door with his shoulders etc.)
WK 2	The burglar tries to open the locked door by physical force and uses additionally simple tools such as screwdrivers, pliers and wedges.
WK 3	The burglar tries to open the locked door additionally with a second screwdriver and a cow bar.
WK 4	The experienced burglar uses additionally sawing and striking tools (hammer, chisel etc.) as well as a cordless electric drill.
WK 5	The experienced burglar uses additionally power tools like e.g. a jigsaw and an angle grinder with a diameter of max. 125 mm
WK 6	The experienced burglar uses additionally electric power tools like e.g. a jigsaw and an angle grinder with a diameter of max. 230 mm
