Corrosion test
ǠDIN 50018
Extreme ambient influences impose
demanding requirements on components
and their labeling and marking.
Two liters of distilled water and one liter of
SO2 gas are introduced into a climate cabinet. Contact comply with this demanding

During the test and at a test temperature
of 40°C, an acidic atmosphere is formed,
which affects the material surfaces of the
test objects. After eight hours of testing, the
test objects dry for 16 hours with an open
door. A microscopic visual check is finally
performed.

The following test method, based on
DIN 50018, describes the corrosion test
in an alternating condensation climate
with an atmosphere that contains sulphur
dioxide.
Salt spray
ǠIEC 60068-2-11/-52
Particularly in shipbuilding, technical
components have to be marked and must
remain permanently legible in corrosive
atmospheres. The salt content of the
air in combination with the increased
humidity places high demands on the
labelings and materials used. On the basis
of IEC 60068-2-11/-52, it is possible to
simulate the influence of a sea climate.
The resistance of the materials in a
corrosive atmosphere is tested using
salt spray. The test objects are placed
in the test chamber and subjected to a
finely dosed spray of 5% sodium chloride
solution (NaCl; pH-value 6.5 - 7.2) at a
temperature of +35°C for a period of
96 hours. A microscopic inspection is
performed after the test. In IEC 60068-
2-52, testing is also performed using 5%
sodium chloride, but under conditions
with different specifications.
Phoenix Contact marking materials fulfill
these stringent requirements and can be
used even in extreme climatic conditions.
