MIL-DTL-23971D

4.7.10 Electromagnetic interference (see 3.5.8). When specified (see 3.1), the electromagnetic interference shall

be measured in accordance with CE101, CE102, CS101, and RE101 of MIL-STD-461.

Conducted emission, 30 Hz to 20 kHz, power leads

Conducted emission, 20 kHz to 50 MHz, power leads

Conducted emission, 20 kHz to 50 MHz, control and signal leads

Conducted susceptibility, 30 Hz to 50 kHz, power lead

Conducted susceptibility, 50 kHz to 400 MHz, power lead

Radiated emission, 30 Hz to 30 kHz, magnetic field

4.7.11 Barometric pressure (reduced) (see 3.6.2). The items shall be tested for barometric pressure in accordance

with method 105 of MIL-STD-202. The following details shall apply:

Mounting: Not applicable.

Test condition: D (100,000 feet), unless otherwise specified (see 3.1).

Test during subjection to pressure: 125 percent of rated power shall be applied between the terminals for

not less than 1 second or more than 5 seconds.

Final measurements: VSWR, insertion loss, isolation, phase balance, and amplitude balance tests as

4.7.12 Thermal shock (see 3.6.3). The items shall be tested in accordance with method 107 of MIL-STD-202, test

condition A. Before and after cycling, the VSWR, insertion loss, and isolation tests as specified in 4.7.4, 4.7.5, and

4.7.6, respectively shall be performed.

4.7.13 Terminal strength (see 3.6.4). The items shall be tested in accordance with method 211 of MIL-STD-202,

test condition A, with a 2 pound pull.

4.7.14 Resistance to solvents (see 3.6.5). The item shall be tested in accordance with method 215 of MIL-STD-

202. Two test solvents may be selected from those defined in method 215, and applied one to each sample. After

the final immersion and brushing, it shall be allowed to dry. When dry, there shall be no evidence of mechanical

damage and the marking shall remain legible.

4.7.15 Resistance to soldering heat (see 3.6.6). The item shall be tested in accordance with method 210 of MIL-

STD-202, test condition D, followed by the VSWR, insertion loss, isolation, phase balance, and amplitude balance

tests as specified in 4.7.4, 4.7.5, 4.7.6, 4.7.7, and 4.7.8, respectively.

4.7.16 Solderability (see 3.6.7). The item shall be tested in accordance with method 208 of MIL-STD-202.

4.7.17 Vibration (see 3.6.8). Unless otherwise specified (see 3.1), the item shall be tested in accordance with

method 204 of MIL-STD-202, test condition A, followed by the VSWR, insertion loss, phase balance, and amplitude

balance tests as specified in 4.7.4, 4.7.5, 4.7.6, 4.7.7, and 4.7.8, respectively.

4.7.18 Shock (see 3.6.9). Unless otherwise specified (see 3.1), the item shall be tested in accordance with

method 213 of MIL-STD-202, test condition G, followed by the VSWR, insertion loss, isolation, phase balance, and

amplitude balance tests as specified in 4.7.4, 4.7.5, 4.7.6, 4.7.7, and 4.7.8, respectively.

4.7.19 Moisture resistance (see 3.6.10). With all connections capped, the item shall be tested in accordance with

method 106 of MIL-STD-202, 1,000 megohms minimum (unless otherwise specified, see 3.1) at +25�C measured

after drying followed by the phase balance, amplitude balance, and power level tests as specified in 4.7.7, 4.7.8, and

4.7.9, respectively. Polarization and load voltage is not applicable.
