Design window assembly using a dynamic analysis to prove the system will provide performance equivalent to or better than Class ER1 rating in accordance with EN 13541 for the peak positive pressure of 158 kilopascals (kPa) and peak positive phase impulse of 462 kilopascal-millisecond (kPa-msec). Use a triangular blast load using the applicable pressure and impulse indicated above. The allowable response limits of steel frame elements must be in accordance with EN 13541 .

1.7.2.3 Standard Airblast Test Method

As an alternative to the 'Computational Design Analysis Method' and 'Dynamic Design Analysis Method' indicated above, window assembly may be tested for evaluation of hazards generated from airblast loading in accordance with EN 13541 by an independent testing agency regularly engaged in blast testing. For proposed window systems that are of the same type as the tested system but of different size, the test results may be accepted provided the proposed window size is within the range from 25 percent smaller to 10 percent larger in area and aspect ratio of the original qualified tested glazing systems in accordance with EN 13541 .

Proposed window system/assembly of a size outside this range will require testing to evaluate their hazard rating or are certified by the 'Dynamic Design Analysis Method' indicated above. Testing may be by shock tube or arena test. Perform the test on the entire proposed window system/assembly, including, the glazing, its framing/support system, operating devices, and all anchorage devices. Window support system replicate anchorage of the window support system with the method of installation to be used for the project. The minimum airblast loading parameters for the test will be as follows: peak positive pressure of 158 kilopascals (kPa) and peak positive phase impulse of 462 kilopascal-millisecond (kPa-msec). The hazard rating for the proposed window systems, as determined by the rating criteria of EN 13541 , to provide performance equivalent to or better than Class ER1. Results of window systems previously tested by test protocols other than EN 13541 may be accepted provided the required loading, hazard level rating, and size limitations stated herein are met.
