Impact sensitivity testing can be completed using the BAM Fall Hammer apparatus developed by the German Federal Institute for Testing Materials (BAM). Impact energy is imparted to a 40mm3 sample by means of a falling weight. The limiting impact energy is determined as the lowest energy at which a flash, flame, or explosion is observed. The test is used to assess the sensitivity of the test material to drop-weight impact. The BAM Fallhammer test is a part of UN Test Series 3 which is used to assess the ignition sensitivity of suspected explosive materials. As many as 54 trials may be performed and therefore approximately 3 cubic centimeters (cc) of sample may be required.
Impact sensitive products are known to have detonated under moderate impacts such would commonly occur in a drill and blast operation.
Sources of impact include drilling, machine excavation, rock crushing and the like.
In its original position or place.
Relates to goods which when mixed or otherwise brought into contact with each other, are likely to interact and increase risk because of the interaction.
Blasting components which provide the transmission of signal, control of delay timing and the initial explosive energy within the blast hole.
