This document specifies a method for determination the ability of the explosive content of plain detonators and semi-finished detonators to withstand vibration it could be exposed to during use, handling and transport. Plain detonators are instantaneous detonators supplied without means of activation. Semi-finished detonators are detonators supplied without means of activation. This document applies to explosives for civil uses. NOTE Plain detonators and semi-finished detonators are normally activated by means of detonating cord, safety fuse, pyrotechnic igniter or shock tube.
