3.6.11 Humidity. When tested as specified in 4.7.12, connectors shall meet the requirements of dielectric withstanding voltage
(see 3.6.6) and insulation resistance (see 3.6.7).
3.6.12 Vibration. When tested as specified in 4.7.13, mated connectors shall not be damaged and there shall be no loosening
of parts due to vibration. Counterpart connectors shall be retained in engagement and there shall be no interruption of electrical
continuity or current flow longer than 1 microsecond.
3.6.13 Shock (specified pulse). When tested as specified in 4.7.14, mated connectors shall not be damaged and there shall be
no loosening of parts, nor shall there be an interruption of electrical continuity or current flow longer than 1 microsecond during the
exposure to mechanical shock.
3.6.14 Durability. When tested as specified in 4.7.15, counterpart connectors shall show no mechanical or electrical defects
detrimental to the operation of the engagement and separation forces after 500 cycles of mating and unmating (see 3.6.9).
3.6.15 Salt spray (corrosion). When sockets as specified in 4.7.16, mated connectors shall show no exposure of base metal
due to corrosion which will affect performance as specified for mating and unmating forces(see 3.6.4) and contact resistance (see
3.6.8).
3.6.16 Oversize pin exclusion. When tested as specified in 4.7.17, socket contacts shall exclude the entry of a test pin .036 inch
(0.91 mm) diameter. After testing, the contacts shall meet the requirements for a contact resistance (see 3.6.8).
3.6.17 Probe damage. When tested as specified in 4.7.18, socket contacts shall meet the requirements of the contact
engagement and separation force and shall show no evidence of visible damage (see 3.6.9).
3.6.18 Fluid immersion. When tested as specified in 4.7.19, unmated connectors shall meet the requirements of mating and
unmating force (see 3.6.4).
