Sandwich Corrosion
per ASTM F 1110
TEST METHOD
- Aluminum panels having clad or anodized nonclad surfaces are sandwiched together with filter paper saturated with the test material between the panels. The sandwiched panels are cycled between warm ambient air and warm humid air for 7 days. The coupons are then inspected to determine whether corrosion more severe than that caused by a reagent water has occurred on the surfaces exposed to the test material. This test method may be used for solutions of dry granular material or for liquid materials.
- Relative corrosion severity rating system:
- No visible corrosion
- Very slight corrosion or discoloration (up to 5% of surface area corroded)
- Slight corrosion (5 to 15%)
- Moderate corrosion (10 to 25%)
- Extensive corrosion or pitting (25% or more)
