What is the difference between the types of explosive blast tests?
The basic differences are within three methods of testing. Two utilize various types of explosives, and the other primarily utilizes regulated compressed air. These are further split into two categories: Open Air Arena and Shock Tube Testing. Open Air Arena tests are conducted in an open field with live explosives detonated at various distances from the test specimen (target). These are conducted on test specimens (in the case of glazings) either mounted into a frame stand or a closed structure replicating a building or similar facsimile. This is the most common method of testing. The tests are conducted with various types of explosives recommended by the manufacturer of the glazings/systems or other government or end users of the product. Each method has its advantages and disadvantages, which are threat specific and based on each product utilized for the testing apparatus and protocol, as well the individual components and assemblies. This becomes evident in the difference between th
