CORROSION
ACCELERATED CORROSION
The purpose of this test is to determine the resistance of materials and
protective coatings to corrosive atmospheres when a more corrosive environment
than the salt fog/spray test is required. The test is used when material
is stored or operated in areas, for example, where acidic atmospheres
exist, such as in industrial areas or near the exhausts of any fuel-burning
device. Gases such as sulfur dioxide are used to replicate the exhausts
of fuel burning devices.
Accelerated corrosion testing is specified in the following:
MIL-STD-810,
ASTM
G43-75
SALT FOG/SPRAY
Salt fog/spray testing determines the effectiveness of protective coatings
and finishes on material. It may also be applied to determine the effects
of salt deposits on the physical and electrical aspects of material. In
general, salt fog/spray is applied to material that will experience significant
exposure to high levels of salt in the environment.
Salt fog/spray testing is specified in the following:
