MIL-PRF-23359H
4.5.4 Offset capability. The detector shall detect a simulated M-16 mine.
Failure to detect the M-16 simulated mine, under the conditions of table II
shall constitute failure of this test.
4.6 Immersed operation. The detector shall detect a M-14 mild steel pin
when the search head receiver coil is submerged 1.5 m below the water/air
interface and is 7.6 cm above the test pin. The test shall be performed in a
3.5 percent synthetic sea-salt solution with a salinity pH value of 8 ±0.2 and
at a temperature of 18 ±10 °C. After a 30-day waiting period, the detector
shall be examined for corrosion. Evidence of corrosion that would affect the
ability of the detector to perform its mission or failure to meet the criteria
described in the sensitivity tests shall be cause for discontinuance of
consideration of the detector. Any leakage or damage to the detector or
failure to detect the M-14 mild steel pin shall constitute failure of this
test.
4.7
Environmental conditions.
4.7.1
Operational conditions.
4.7.1.1 Leak test. The detector, with headset, shall be completely
immersed in water so that all parts are 1.5 meters below the air-water
interface for a period of two hours. The headset shall be removed after 5
minutes of immersion and allowed to dry for the remainder of the 2-hour
immersion test. The temperature of the water shall be 18 ±10 °C. Bubbles
emanating from within the detector shall be considered a leakage. However,
bubbles which result from trapped air on the various exterior surfaces of the
detector shall not be considered a leak. If leakage is observed, the test
shall be discontinued. After the 2-hour immersion, the detector shall be
assembled and tested in accordance with 4.5.1.a, b, and c, for all targets.
Any leakage damage to the detector or failure to operate in accordance with
4.5.1 shall constitute failure of this test.
4.7.1.2 Sand and dust. The sand and dust concentrations shall be 0.177
grams/cubic meter (natural conditions) and tested with a velocity of 8
meters/second. The detector head and electronic package faces shall be
oriented toward the blowing sand and dust for a minimum of 90 minutes. After
the test, the detector shall be assembled and tested in accordance with 4.5.1
a, b, and c, for all targets. Heavy surface erosion/abrasion, penetration of
seals, function impairment or failure to operate in accordance with 4.5.1
shall constitute failure of this test.
4.7.1.3
High/low temperature operation and thermal shock.
4.7.1.3.1 High temperature operation. Place the disassembled detector in
the chamber and increase the temperature to +51 ±2 °C. Maintain this
temperature for 3 hours, assemble, and remove the detecting set from the
chamber. Test in accordance with 4.5.1, starting within 5 minutes and
completing within 30 minutes after removal from the chamber. Return the
detector to the chamber and duplicate this test for six continuous cycles.
After the sixth cycle, test in accordance with 4.5.1.a through 4.5.1.c, using
all targets. These tests shall start within 5 minutes after removal of the
detector from the chamber. Failure to operate in accordance with 4.5.1 or
