The DIN 50 018 standard give conditions
for Kesternich Corrosion test. This test has been
done to simulate industrial or urban atmosphere, by means of the formation of
an artificial atmosphere, adding to the air Sulphurous Anhydrid, with or
without carbon dioxide.
With the Kesternich’s Test we can get an artificial
atmosphere with the best approximation to the results obtained when in
sulphurous natural atmospheres some metals are expounded to it.
The Kesternich Test
consists of a cycle of 24 hours slit in two parts: the first one consists of 8
hours with closed chamber and the pieces in its indoor, situated according to
the Regulations and expounded to 40ºC inside of which 0,2 or 2 liters/ gr. of
Sulphurous Anhydrid are introduced with a 100% of RH.
After this period of time, another stage of 16 hours
goes on. In this stage the door is open, the heating is stopped and the pieces
are exposed to the Ambiance Temperature of the air (according to SFW variant of
the DIN 50.017/ 50.018). The test finishes when an inadmissible influence
appears in the aspect of the expounded pieces or when the accorded number of
cycles for the Test's duration has been reached.
DYCOMETAL, company with over 25 years experience in developing
simulation chambers for environmental testing, offers customers Kesternich test chambers to carry out such tests.
