<b>Corrosion</b><br/>No damages (corrosion) on the metal body that affect the usual functions.
<b>Dimensional examination</b><br/>For all individual parts, approvals for the current revision status are present.
<b>Electrical load and temperature</b><br/>The sum of ambient temperature and temperature rise of a plug connector may not exceed the upper limiting temperature.
<b>Fluid resistance</b><br/>No change in material properties which might constrain the normal use.
<b>Gauge retention force</b><br/>After 3 times plugging with max. gauge the tested contacts must still be able to hold the min. gauge.
<b>IP6X</b><br/>No ingress of dust.
<b>IPX5</b><br/>Water projected in jets against the enclosure from any direction shall have no harmful effects.
<b>IPX7</b><br/>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.
<b>Polarization and coding</b><br/>No damages which might affect the usual functions.<br/>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
