Abstract: This paper presents a measuring technique by the application of argon flash bombs, which allows photography of fragments or pellets as illuminated points with a simple Polaroid camera. This method enables rapid measurement of fragment or pellet pattern-space and velocity distribution-in acceptance tests in spite of the small size of the fragment, such as only 2.4 mm diameter. This method does not need extensive test facilities, large amounts of test materials, nor protracted evaluation time for the analysis, and can be conducted on a test range.
