STANDARDIZATION OF THE SMALL SCALE GAP TEST USED TO MEASURE THE SENSITIVITY OF EXPLOSIVES

Abstract

A revised small scale gap test (SSGT) has been developed. It employs a 1.4-inch long, 0.2-inch diameter RDX column loaded in a brass cylinder as a donor. The acceptor is of similar configuration. The sensitivity of the explosive loaded in the acceptor is determined by the test as a function of the thickness of the lucite barrier which is used to moderate the donor output. The mean firing sensitivity, for instance, is determined from the thickness of lucite at which 50% response would be expected. By revision of methods and design, and by careful control of the loading and the testing conditions, the resolution of the revised SSGT has been improved by a factor of 4 to 5 over that of the original SSGT.
