3.11 Insulation resistance. When adapters are tested as specified in 4.5.8 , the insulation

resistance shall not be less than that specified (see 3.1).

3.12 Voltage standing wave ratio (VSWR). When adapters are tested as specified in 4.5.9, the

VSWR shall not exceed that specified over the frequency range specified (see 3.1).

exceed that specified (see 3.1).

3.14 RF insertion loss. When adapters are tested as specified in 4.5.11, the insertion loss shall not

exceed that specified (see 3.1).

3.15 Adapter durability. When adapters are tested as specified in 4.5.12, they shall show no

evidence of severe mechanical damage and the coupling device shall remain functional. Adapters

shall meet the applicable requirements of 3.6 and 3.8.

3.16 Dielectric withstanding voltage. When adapters are tested as specified in 4.5.13, there shall

be no evidence of breakdown.

3.17 Contact resistance. When adapters are tested as specified in 4.5.14, the contact resistance of

the center contact and outer contact shall be as specified (see 3.1).

3.18 Vibration. When adapters are tested as specified in 4.5.15, there shall be no electrical

interruptions exceeding 1 microsecond (�s), or as otherwise specified (see 3.1). There shall be no

evidence of visual mechanical damage after the test, and the contact resistance of the center contact

shall not exceed the specified amount (see 3.1 and 3.17).

3.19 Shock (specified pulse). When adapters are tested as specified in 4.5.16, there shall be no

electrical interruptions exceeding 1 �s unless otherwise specified (see 3.1). There shall be no

evidence of visual or mechanical damage after the test, and the contact resistance of the center

contact shall not exceed the specified amount (see 3.1).

3.20 Thermal shock. After testing as specified in 4.5.17, there shall be no evidence of visual

mechanical damage to the adapter and it shall meet the dielectric withstanding voltage requirement

(see 3.16), and the contact resistance specified for the center contact shall not be exceeded (see 3.1

and 3.17).

3.21 Moisture resistance. When adapters are tested as specified in 4.5.18 , there shall be no

evidence of damage. They shall withstand the dielectric withstanding voltage specified (see 3.16),

and the insulation resistance shall not be less than that specified (see 3.11).

3.22 Corona level. When adapters are tested as specified in 4.5.19, at the altitude and voltage

specified (see 3.1), there shall be no evidence of sustained corona discharge.

3.23 RF high potential withstanding voltage. When adapters are tested as specified in 4.5.20, there

shall be no breakdown, and the leakage current specified shall not be exceeded (see 3.1).

3.24 Corrosion (Salt spray). When adapters are tested as specified in 4.5.21, there shall be no

exposure of the base metal on the interface or mating surface, and they shall meet the requirements

of 3.6.1 or 3.6.2 as applicable.
