RP-4 SFF EBW Self Forging Fragment
The RP-4 SFF is a copper liner,Self Forging Fragment (also referred to as an Explosively Formed Projectile or Misnay-Schardin device) initiated by an integral Exploding Bridgewire detonator. Threshold and firing energy requirements are the same as for the RP-1 EBW detonator, P/N 167-4314. Performance is greater than 0.5 inches perforation into a mild steel target at a 10 caliber standoff.
RP-4 SFF Self Forging Fragment Firing Parameters
|Threshold Burst Current:||190 amps|
|Threshold Voltage:||500 volts|
|Threshold Voltage Std. Deviation:||10 volts maximum|
|Caution: While EBW and EFI Initiators are inherently less susceptible to accidental detonation during handling and set-up than devices containing primary explosives, electrical and electronic firing systems are sensitive to transient electrical energies which could cause premature triggering or firing. The blasting area must be clear of personnel and equipment before the detonator leads are connected to any RISI Firing System. Only approved RISI Firing Systems should ever be used to initiate or detonate any explosive product manufactured and authorized for sale by RISI.|
