Revision of F2927-12 Standard Test Method for Door Systems Subject to Airblast Loadings

Rationale

Test results from the use of this method have shown that, if not properly prepared, items on a door such as window glass, ancillary hardware Items, trim pieces, and fasteners can become projectile hazards. The test method already recognizes this hazard in stating that debris cannot strike the witness panel. However, there are a myriad of commercial door hardware combinations available and extrapolation of tests results is often done. Often, specifiers ignore hardware items mounted on the presumed safe side of the door. There is evidence that when light-gauge hollow-metal doors with conventional hardware are tested from 6 to 12 psi that hardware components can become flying debris hazards even when the door panel and frame obtain desired results. Of course, as the blast pressure increases say, above 12 psi, the striking velocity of these projectiles would also increase to potentially hazardous levels. This update adds verbiage to address this concern.
