SMRT No. 10090-00 Addendum No. 1 Page 2 of 7

H. Minimum Antiterrorism Performance Criteria: Windows shall meet the performance requirements below:

1. Computational Design Analysis Method: Windows shall resist a static load of 1 lb. per square inch applied perpendicular to the surface of the glazing and frame. Aluminum frame members may be designed based on 0.2% offset yield strength. Deformations shall not exceed l/60 of the unsupported member lengths. Equivalent static design loads for connections of the frames to the surrounding structure, the door hardware, associated internal door and frame connections, and glazing stop connections shall be 10.8 pounds per square inch for glazing panels with a vision area less than or equal to 10.8 square feet, and 4.4 pounds per square inch for glazing panels with a vision area greater than 10.8 square feet but less than or equal to 32 square feet.

(Vision area is defined as the area through which light may be seen.)

Connections and hardware may be designed based on ultimate strength for steel and 0.2% offset yield for aluminum. Ultimate strengths and yield strengths may be increased by a factor of 1.1 over specified values. In addition, all safety factors used in blast-resistant structural design may be removed except for safety factors relating to shear.

2. Standard Airblast Test Method: Each minimum antiterrorism window type shall be tested for evaluation of hazards generated from airblast loading in accordance with ASTM F 1642 by an independent testing agency regularly engaged in blast testing. For proposed windows that are of the same type as the tested system but of different size, the test results may be accepted provided the proposed door and frame size is within the range from 25% smaller to 10% larger in area, than the tested door and frame. Proposed windows of a size outside this range shall required testing to evaluate their hazard rating. Tested may be by shocktube or arena test. The test hall be performed on the entire proposed window, which shall include, but not be limited to, the glazing, it’s framing system and all anchorage devices.

Anchorage of the frame or subframe shall replicate the method of installation to be used for the project. The minimum airblast loading parameters for the test shall be as follows: Peak positive pressure of 5.8 psi and positive phase impulse of 41.1 psi-msec. The hazard rating for the proposed window systems, as determined by the rating criteria of ASTM F 1642, shall not exceed the “Very Low Hazard” rating (i.e. the “No Break,” “No Hazard,”

“minimal Hazard” and “Very Low Hazards” ratings are acceptable. “Low

Hazard” AND “High Hazard” ratings are unacceptable). Results of windows previously tested by test protocols other tha ASTM F 1642 may be accepted provided the required loading, hazard level rating and size limitations stated herein are met.
