ASTM G8 Cyclic Salt Fog Corrosion Test Chamber

ASTM G85 - 09 Salt Spray Testing

A1. Acetic Acid-Salt Spray (Fog) Testing

1. temperature in the saturator tower (bubble tower) is 47 +/-1°C

2. acetic acid salt spray fog chamber temperature at 35 +/- 2 °C

A2. Cyclic Acidified Salt Fog Testing

1. temperature in the saturator tower (bubble tower) is 57 +/-1 °C

2. salt spray chamber temperature at 49 +/-2 °C .

3. Make sure an inch or so of water is present in the bottom of the box

4. 6h repetitive cycles : 3/4-h spray; 2-h dry-air purge; 13/4-h soak at high relative humidity

5. purge

6. Collect the fog in a special continuous spray run of at least 16 hours periodically between test runs.

A3. Acidified Synthetic Sea Water (Fog) Testing

1. PH of salt solution between 2.8 ~ 3.0.

2. temperature in the saturator tower (bubble tower) is 47 +/-1 °C , if cabinet temperature is 35 °C .

temperature in the saturator tower (bubble tower) is 57 +/-1 °C , if cabinet temperature 49 °C .

3. An rich or so of water should always be present in the bottom of the box

4. Equip the cabinet with a timing device that can be used for the following cycle: 30 min spray followed by 90-min soak at above 98% relative humidity

A4. Salt/So2 Spray (Fog) Testing

1. temperature in the saturator tower (bubble tower) is 47 +/-1 °C

2. salt spray chamber temperature at 35 +/- 2 °C

3. So2 Gas - Equipment and materials required for addition of SO2 to cabinet are as follows

3.1. Cylinder of So2 gas.

3.2. Flowmeter capable of measuring So2 gas flow of 1 cm3/min.ft3 of cabinet volume (35 cm3/min.m3); also constructed of materials inert to So2 gas.

3.3. Timer

3.4. Two-way solenoid valve fabricated of materials inert to So2 gas.

3.5. Tubing and fittings for So2 line of materials inert to So2 gas.

4. PH of the collected solution shall range from 2.5 to 3.2.

5. So2 gas for 1h 4*a day (every 6h)

1/2-h salt spray, 1/2 So2. 2-h soak

A5. Dilute Electrolyte cyclic fog/dry testing

1. Wet/Dry Cycle - The cycle consists of 1-h fog followed by 1-h dry-off

2. During the fog period, the fog exposure is at ambient room temperature and conditions.

3. Dry-off temperature - the temperature throughout the exposure zone shall reach and

remain at 35 +/-1.5 °C within 3/4-h of switching from the fog period to the dry period

4. The dry-off is achieved by purging the chamber with fresh air, such that within 3/4-h

all visible moisture is dried off of the specimens.
