13.8.1. Ordnance Test Equipment General Design Requirements
|
I
|
|
|
13.8.1.1. All ordnance test equipment, such as continuity and bridgewire resistance measurement devices, shall be inspected and tested for voltage and optical isolation and limitation.
|
C
|
|
|
13.8.1.1.1. These devices shall be designed so that they will not pass greater than 1/10 of the no-fire energy across an EED bridgewire, or 50 mA, whichever is less.
|
C
|
|
|
13.8.1.1.2. These devices shall be analyzed to verify that rough handling, dropping, or single component failure will not result in negating the current-limiting feature.
|
C
|
|
|
13.8.1.1.3. Clear cases of unacceptable energy or current for a particular resistance range or ranges shall be excluded from use by disablement by the manufacturer or local authority before certification.
|
C
|
|
|
13.8.1.1.4. Certification of each device shall include a tabular listing (to be kept with or marked on each meter) of the energy level and current levels available at each of the selectable ranges for the meter.
|
C
|
|
|
13.8.1.1.5. All test equipment shall be designed to meet standard industry safety requirements such as those established by ANSI, IEEE, and NFPA, as well as applicable Volume 3, Chapter 14 requirements.
|
C
|
|
|
13.8.1.2. The test results shall be submitted to the PSWG for PSWG and Range Safety approval before equipment use at the payload processing facility and launch site area.
|
C
|
|
|
13.8.2. Stray Current Monitors
|
I
|
|
|
13.8.2.1. A stray current monitor shall be provided for all low voltage (EED) solid rocket motor ignition circuits and other high hazard ordnance systems as determined by the PSWG and Range Safety.
|
C
|
|
|
The term high hazard refers to specific catastrophic events such as the inadvertent firing of a solid rocket motor or actuation of a destruct system that could result in multiple fatalities, typically threatening more than just the ordnance technicians handling the hazardous item, and/or "total" destruction of high value hardware such as the payload, launch vehicle, or facility.
|
I
|
|
|
13.8.2.2. The stray current monitor shall be installed and remain connected until the electrical connection of the actual initiators is accomplished. The monitor shall be installed at a time determined by the PSWG, Range Safety and the payload project.
|
C
|
|
|
13.8.2.3. The stray current monitor shall provide a stray current device capable of detecting 1/10 of the maximum safe no-fire current.
|
C
|
|
|
Fuses or automatic recording systems capable of detecting 1/10 of the maximum safe no-fire current are acceptable stray current devices for the stray current monitor.
|
I
|
|
|
13.8.2.4. The monitoring device shall be installed in the firing line.
|
C
|
|
|
13.8.3. Ground Support Test Equipment. The design of test equipment used to test ground support equipment shall be reviewed and approved by the PSWG and Range Safety.
|
C
|
|
|
13.8.4. Laser Test Equipment
Note: Laser test equipment are not anticipated to be used. If they are used they must comply with AFSPCMAN 91-710, Volume 3, section 13.8.4.
