CTL22 - BAM Fallhammer Test Apparatus

For determining the sensitivity of powders to impact stimuli for assessing transport, packaging and regulatory classification (UN, EC and EMTAP).


  • Excellent for screening products for sensitivity to impact stimuli in order to determine whether a substance is an impact sensitive explosive
  • Excellent screening tool for classifying a product for transport and EU packaging and labeling classification
  • Simple to use electromagnetic drop weight release mechanism
  • Robust design

Some powders are deliberately manufactured with such highly energetic behaviour, but occasionally it is an unexpected property of a new material. For regulatory compliance there are a number of screening tests which have to be performed on new materials in order that they can be safely transported. One such screening is a BAM Fallhammer test, which measures sensitivity to mechanical force, testing to UN, EU & EMTAP Regulations.
