4.6.2
Performance tests.
4.6.2.1 Function test. The function of the signal kit shall be determined. Only launchers and
flares meeting the safety inspection criteria in 4.6.1 shall be used for this test. The launcher shall
be held for firing with only one hand, signal end up in a true vertical position, and a minimum of
12 inches above the head, or the launcher shall be fixed for remote firing in a suitable test fixture.
a. After loading the signal into the launcher, the loaded launcher shall be aimed
vertically at the ground to ensure that the signal does not fall out of the launcher.
b. A maximum of two attempts to initiate the signal shall be made, except that a
maximum of four attempts shall be made with signals that have been subjected to low
temperature (see 3.8.1.1 and 3.8.3.3).
c. When the signal is fired, it shall not be held captive in the launcher while the rocket
motor burns.
d. When the signal is fired, it shall not explode or deflagrate, and components of the
signal shall not separate or come apart within 15 feet of the launcher.
e. The rocket motor shall not vent such that the propellant system is snuffed out after
initial ignition.
f. The height at which the candle ignites shall be in accordance with table I.
g. The burn time of the display shall be in accordance with table I.
h. The apogee altitude of the display shall be in accordance with table I.
i. The angular deviation from vertical of the signal at apogee shall not exceed 30° with
wind conditions of 10 miles per hour or less.
j. The candle shall burn out prior to hitting the ground.
4.6.2.2 Burn time, candlepower, and color tests. Tests for burn time, candlepower, and color
shall verify the performance of the candle only and can be accomplished by igniting the candle in
a lab environment
4.6.2.2.1 Burn time test. The burn time of the candle shall be in accordance with 3.5.2.1.
4.6.2.2.2 Candlepower test. The minimum luminous intensity and minimum average
candlepower of the candle shall be 26,000 lumen seconds and 2,500 lumens, respectively (see
6.4.1).
4.6.2.2.3 Color test. The dominant wavelength and the purity of color of the candle shall be 620
±20 millimicrons with a purity of 76 percent (see 6.4.1).
