In the safety assessment of munitions, the explosives used must be identified. In addition to national legislation and regulatory requirements, the safety and suitability of the explosives used by military services is assessed according to STANAG 4170 before selection and incorporation into the munition. Explosive components used in fuzing systems normally contain explosives that are more sensitive than main charge explosives. Small changes of loading conditions involving pressure-density andor confinement can radically alter their performance and characteristics, which can affect their safety. Therefore, it is essential that these effects are thoroughly assessed during development and, if necessary, in production. The Explosive Component Water Gap Test ECWGT has been developed to assist in this assessment. The aim of this paper is to give the background to and explain the conduct of the ECWGT, a means of testing the shock sensitiveness of explosive components cheaply and in a reproducible manner. The paper is intended to extend the test method to cover cord- and tube-shaped explosive components as well as ignition transfer elements.
