Corrosion
No damages (corrosion) on the metal body that affect the usual functions.
Dimensional examination
For all individual parts, approvals for the current revision status are present.
Electrical load and temperature
The sum of ambient temperature and temperature rise of a plug connector may not exceed the upper limiting temperature.
Fluid resistance
No change in material properties which might constrain the normal use.
Gauge retention force
After 3 times plugging with max. gauge the tested contacts must still be able to hold the min. gauge.
IP6X
No ingress of dust.
IPX5
Water projected in jets against the enclosure from any direction shall have no harmful effects.
IPX7
Ingress of water in quantities causing harmful effects shall not be possible when the enclosure is temporarily immersed in water under standardized conditions of pressure and time.
Polarization and coding
No damages which might affect the usual functions.
Mating of the connectors should only be feasible in the right position and right combination. Mating in wrong position has to be prevented by constructional mea
