MIL-STD-202. The following details and exceptions shall apply:
a.
Test condition - C.
b.
Cooling time prior to final measurements - one hour.
c.
Measurements after test - Nominal voltage and clamping voltage shall be measured as specified in 4.8.2 and
4.8.3 respectively.
d.
Examination after test - Resistors shall be examined for evidence of mechanical damage.
e.
Method of internal examination - Not applicable.
4.8.11 Resistance to solvents (see 3.16). Resistors shall be tested in accordance with method 215 of
MIL-STD-202. The following detail and exception shall apply:
a.
Examination after test - Resistors shall be examined for evidence of mechanical damage and legibility of
marking.
4.8.12 Flammability (see 3.17). Resistors shall be tested in accordance with method 111 of MIL-STD-202. The
following details and exceptions shall apply:
a.
Mounting - Resistors shall be mounted with the leads horizontal and the body vertical.
b.
Point of impingement - The resistor body shall be centered, 1.5 inch, -0.0, +0.25 inch (38 mm, -0, 6.35 mm)
above the nozzle rim.
c.
Duration of flame application - The flame shall be applied until flaming combustion of the resistor is visible or,
for a maximum of 15 seconds in any case.
d.
Dry absorbent surgical cotton shall be placed 12 inches (305 mm) below the resistor.
e.
Examinations during and after test - The time for flaming combustion of resistors to self-extinguish and the
time of persistence of glowing combustion of resistors shall be recorded. The dry absorbent surgical cotton
shall be observed for ignition.
4.8.13 Terminal strength (see 3.18). Resistors shall be tested in accordance with method 211 of MIL-STD-202.
The following details and exceptions shall apply:
a.
Test conditions - A and C (pull test and bend test, respectively).
b.
Applied force - Test condition A; 5 pounds. Test condition C; 1 pound.
c.
Examination after test - Resistors shall be visually examined for evidence of mechanical damage.
