Krieger's Forced Entry Door
Watch the Door Being Tested to the SD-STD-01.01 Forced Entry and Ballistic Resistance Standard
The US Department of State developed the SD-STD-01.01 Forced Entry and Ballistic Resistance of Structural Systems standard for high risk buildings.

The tests requires that the door core must stop multiple rounds of 7.62 mm from a NATO rifle—firing 150 gr. full metal jacket ammo.

Then, the door must withstand a six-man team attacking the door with everything from sledgehammers to battering rams.
