Detention security hollow metal manufacturers shall submit to the Architect, twenty-one (21) days prior to bid date, independent testing laboratory report certifying the following minimum performance of 3’0 x 7’0” x 14 gauge minimum, flush door.

  1. Static Load Test
    Under a centrally applied load of 14,000 lbs. At quarter points the maximum midspan deflection shall not exceed 0.58 in. After release of load, deformation shall not exceed 0.015 in.Refer to figure 4 for illustrations of test set up.
  2. Rack Test
    Under a concentrated load of 7,500 lbs. On one unsupported corner of door, the maximum deflection shall not exceed 3.5 in. There shall be no bucking or failure of welds.Refer to figure 5 for illustration of test set up.
  3. Impact Load Test
    1. 1. A 3’0” x 7’0” door frame and hardware assembly shall be constructed and rigidly mounted in the vertical position so that the door and locking hardware are operable. The door shall swing 1 ½ pairs of full mortised butt hinges and shall be locked using a recognized detention security lock with bolt size not to exceed 2” high 2 ¾” wide and latch throw not to exceed 5/8”.A pocket lock mounted in the door is used because the preparation is the most detrimental to the door construction. By using this type lock the most vulnerable case is being tested.

      Refer to Figure 6 for illustration of door and frame assembly.

    2. A door ram pendulum system capable of delivering consistent impacts of up to 200 ft-lbs shall be constructed so that impacts may be delivered to any area of the assembly.200 ft-lbs is used because it has been established experimentation that a person with an 8 lb. sledge hammer or several persons with a battering ram can develop up to 200 ft-lb. of impact energy per blow.

      Refer to Figure 7 for illustration of ram pendulum system.

    3. The ram pendulum system shall be positioned opposite the door side of the assembly so that the door swings away from the ram. While hanging at rest the ram shall be positioned so that the striking nose just touches the target area of the door. The striking nose of the ram shall be made of C1010 or C1020 low carbon steel. The striking surface area of the nose shall be 4.0 ± 0.04 sq. in.4.0 sq. in. is the approximate striking surface area of an 8 lb. sledgehammer.
    4. With door closed and locked, and the above testing arrangement secured, the following series of impacts shall be delivered to the assembly. The ram shall be raised to height so that when released it will strike the door with 200-ft-lbs. of energy with each impact.
  1. 400 impacts on the door within 6” of the bolt
  2. 50 impacts on the door within 6” of middle hingeA total of 450 blows are used in the test because this is about the maximum number of blows that any one assembly might receive in a 45 to 60 minute time period. This is the time that is usually required to restore order in major riot situation.
  • The door shall remain closed and locked throughout the testing procedure, and the assembly shall not be damaged to the extent that forcible egress can be obtained. After testing is completed the door shall be capable of being unlocked and operated to provide egress.
  • Removable Glazing Stop Test
    1. A rectangular view window test frame shall be constructed with a glass opening size of 28” x 33” + 1”. The frame shall be constructed of commercial quality steel meeting ASTM 366 or A 569, 12-gauge maximum.The test frame opening size was chosen because it is representative of the view window sizes of average control rooms, day rooms and guard stations. 12 gauge is customarily the maximum used for detention frames.

      Refer to figure 8 for test frame dimensions.

    2. A steel plate of 3/8” minimum thickness shall be glazed in place using the specified glass stop method.A steel plate is used in lieu of security glass for testing purposes. The plate acts as a median through which impact energy is transferred to the removable glass stops.

      Refer to figure 9 for details of the test frame assembly and to figure 10 for details of the glass stop and reinforcement.

    3. The test frame assembly shall then be rigidly fixed in the horizontal position with the removable glass stop on the lower side.
      1. A target on the topside of the 3/8” plate shall be marked in one corner no more than 6” away from the stops.An attacker will most likely strike the glass at a corner knowing that it is the weakest point, hence the location of a test target near the corner. Also, striking the plate in the center will allow dissipation of much of the impact energy through deformation of the plate and vibration. Striking it in the corner will transmit the maximum amount of impact energy from the ram to the stops, again producing the most vulnerable condition.
    4. Impact dart capable of developing up to 400 ft-lbs of impact energy to the plate and whose impact surface area 4 sq. is in shall be positioned to strike the target.Impact energy of 400 ft-lbs. per blow is used because there is a high impact resistant glass on the market which resists 400 ft-lbs. of impact energy. This will ensure that regardless of the glass used, the removable stops will be at least as impact resistant as the glass.

      Refer to figure 11 for illustration of test set up.

    5. Ten (10) impacts of 400 ft-lbs. each shall be delivered to the target. The removable glass stops shall remain undamaged and the 3/8” plate shall remain firmly in place. There shall be no more than one (1) broken fastener in the assembly after impact testing.High impact resistant glass is usually tested at one to five impacts are applied in this case to ensure that the stops have adequate impact fatigue strength and also to more closely simulate actual field conditions.
  • Bullet Resistance
    1. Where specified on individual openings, bullet resistance shall be certified by underwriters Laboratories, Inc. under their testing procedure described in UL Standard #752. The bullet resistance rating shall be “super-power small arms: 44 Magnum Revolver.”The 44 Magnum Revolver is used in this specification because it is the most powerful commonly available handgun. According to prison officials, High Armory handguns, however, could be obtained in a riot situation. For this reason it is recommended that all doors which are indicated on his door schedule to be bullet resistant, and be certified for the 44 Magnum Revolver.
    2. As an alternate, a sample door shall be constructed, tested, and certified by a qualified independent testing laboratory in accordance with the test procedure outlined UL Standard #752. In this case test reports shall include complete descriptions of the test procedure and results. Firearms and ammunition used shall be certified as being correct with respect to bullet caliber, weight, muzzle velocity, and muzzle energy.
  • Test Reports
    All test reports shall include details of test samples and details of photographs of the testing apparatus. The test samples shall be retained at the manufacturer’s facilities for possible inspection.
  • Job Site Door Check
    At the owner’s option, a door at the job site may be selected at random, sawed in half to verify if the door was constructed in accordance with test report details. If the door details do not conform to the specification, the door will be replaced at the manufacture’s expense and replaced with doors that meet the requirements.


  1. Manufacturer’s Qualification
    In order to be approved as an acceptable bidder, each manufacturer, without exception shall submit the following materials twenty-one (21) days prior to bid date.
