What Does Forced Entry Ballistic Rated Mean?

Forced Entry/Ballistic Rated (FE/BR) is a security concept standardized by the U.S. DOS, ASTM (F3038-14), and others to create distinct levels of Forced Entry Protection for structural systems. 

The Forced Entry portion is generally divided into 5-minute, 15-minute, 30-minute, and 60-minute levels.  Depending on the level, the structure is tested by two or six-man teams. These teams will try to gain entry to (or bypass) the structure using a variety of weapons and tools, including sledgehammers, crowbars, hammers, screwdrivers, chisels, and possibly a propane torch.

The Ballistic Rated portion establishes military rifles as the required level of ballistic protection according to DOS policy. Further, shotgun rounds are used to test potentially vulnerable areas or passages such as a transaction window or built-in deal trays.

Concurrent testing is used to evaluate the structure based on both threat types. Structures are "tested to failure," and testing is typically completed whenever the test shape (12"x12"x8" box) can be passed through an opening or breach in the structure.  The structure will be rated based on the highest threshold it surpasses.
