ASTM G85 Annex A1 Acetic
Acid-Salt Spray Test, Continuous
In this variation of the basic Salt Spray
Test the 5% sodium chloride solution is acidified to a ph of 3.1 to 3.3 by
adding acetic acid. The temperature in the Fog chamber is maintained at 35°C +
1.1 or-1.7°C (95°F+2 or -3°F).
This test may be as short as 16 hours. But it is often run
for 144 hours or even as long as 240 hours. At these extended lengths it is very
useful for researching parameters associated with the electroplating of
decorative chrome plating of die-cast steel or zinc. It is also used for the
evaluation of quality in a product.
