BAM Friction Sensitivity Tester
This instrument employs the BAM pendulum-porcelain rod method to determine friction sensitivity of energetic materials. The sample is placed between a porcelain rod and plate, subjected to friction induced by a standard pendulum blow. The system detects explosive reactions and calculates probability values for sensitivity grading, production facility hazard division assessment, and transport classification.
