Rk. Wharton et Ja. Harding, A STUDY OF SOME FACTORS THAT AFFECT THE IMPACT SENSITIVENESS OF LIQUIDS DETERMINED USING THE BAM FALLHAMMER APPARATUS, Journal of hazardous materials, 37(2), 1994, pp. 265-276
We report the results of a systematic investigation of the effect of t
wo experimental parameters on the results obtained using the BAM Fallh
ammer test for liquids. We demonstrate that the impact sensitiveness o
f liquids can be highly dependent on the initial gap set between the i
mpact surfaces and also on the position occupied by the test material.
From pressure measurements taken in the reaction chamber, a relations
hip is derived between the pressure generated on impact and the likeli
hood of ignition. The findings of our study, particularly the dependen
ce of sensitiveness upon the initial gap, will have implications to sc
hemes that employ the BAM Fallhammer test as part of the determination
of hazardous properties (e.g. UN Test Series 3). Some recommendations
are therefore made concerning changes to published impact test proced
ures for liquids.
