I have a specification that references “UFC 4-010-01 Minimum Antiterrorism Standards for Buildings”. What type of doors are required to meet this spec?

The Department of Defense created the referenced document to provide a minimum level of protection from blast forces from acts of terrorism. The door assemblies offered by SDI members are specifically engineered and certified for these applications, with a wide variety of blast resistant capabilities. In order to supply the correct door assemblies, you will need to know the PSI/MSEC value (pounds per square inch / millisecond). This is a value that has been calculated by a blast consultant, and would be expressed as a numerical value, i.e. 50 PSI/MSEC. The higher the value the more blast force the opening is designed to withstand. Matching that value to a manufacturer’s certification will allow you to select the correct door, frame, glazing and hardware configuration.

Note: There are many other blast resistant specifications in addition to UFC 4-010-01. Please also keep in mind that the version of the specification is critical, particularly with the UFC 4-010-01 specification.
