Corrosive Atmosphere
| Corrosive Atmosphere tests are performed to determine the effects of an acidic atmosphere on equipment or materials. These conditions may be either naturally occurring conditions or a result of man made pollutants. Typical atmospheres are comprised of salt (NaCl) spray with additional contaminants, such as sulfur dioxide. The effects can be divided into four broad categories: | |
| Effects | |
 Corrosion of finishes
|
|
| Corrosion of
components such as precision springs |
|
| Impairment of
electrical operations |
|
| Impairment of
mechanical operations |
|
| Procedure | |
| This test is typically performed in a test chamber at an elevated temperature of approximately 90° F. The test unit is suspended in a corrosive atmosphere, sometimes in combination with an atomized salt solution, for a typical duration of from seven to thirty days. The most common corrosive component is sulfur dioxide, which combines with moisture to form acid rain, a mild solution of sulfuric acid. | |
