A number of insensitive high explosives IHE and formulations which were determined to have unexpectedly high sensitiveness by Rotter impact testing F of I 60-110 were further assessed by Rotter powder explosiveness testing. Analysis shows that the hazard as reflected by the ability to propagate following ignition, was low. Risk, defined as the product of hazard and frequency F of I, was similar to assessment based on US impact test data for these materials. An assessment of both the usefulness and the quantitative nature of powder explosiveness testing is made. Guidelines for using Rotter data for deciding relative risk from handling of relatively small quantities of IHEs in R D are given. The desirability of carrying out charge hazard testing to support these risk assessments is stressed.
