Density is controlled through consistency of crystalline structure, precision weighing and class ‘A’ dies and tooling. The result is a detonator with a transmission time simultaneity standard deviation of less than .025 microsecond. While some applications may not require this degree of timing or safety, users may want to take advantage of the high degree of reliability RP-1 Firing Parameters Threshold Burst Current: 190 amps Threshold Voltage: Approx. 500 volts Threshold Voltage Std. Deviation: 10 volts maximum Function Time: 2.75 µsec. typical Function Time Simultaneity Standard Deviation: 0.025 µsec Max. 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.
