Rotational Firing
Modern test stands are also equipped for environmental testing (e.g.,
temperature changes, vibration, impact, and drop tests).
Rotational Firing
Delay blasting system used so that the detonating explosives will
successfully displace the burden into the void created by previously
detonated explosives in holes, which fired at an earlier delay period.
Round Robin Test
Ringversuch
Round Robin tests are testing procedures, developed by the joint
effort of several institutes in different countries, with the purpose of
obtaining comparable results. Such international tests are particularly
useful if they are recognized as binding acceptance tests in the sales
of munition from one country to another.
SAFE & ARM
Device for interrupting (safing) or aligning (arming) an initiation train of
an explosive device, i.e., bomb or warhead.
Safety Diaphragm
Berstscheibe; diaphragme de securité
Diaphragm, usually metal, that will rupture in the event that excessive
gas generator chamber pressure develops.
Safety Fuses
Schwarzpulverzündschnüre; mêches de sureté
274
Safety fuses are black powder cords with an external yarn winding
adjusted to a definite combustion rate – usually 120 s/m. The purpose
is to initiate the explosive charge by igniting the blasting cap of the
primer. The fuse must be freshly cut in the plane perpendicular to its
axis, and the plane of the cut must reach the ignition level of the cap.
The length of the fuse depends on the safety period required. The
structure of the fuse comprises a black powder core with one or two
marking threads, the color of which indicates the identity of the manufacturer,
two or three layers of yarn wound around it (jute, cotton, or
some other yarn), a bitumen impregnation, and a plastic coating.
