What Does Subtropical Testing Mean?
Subtropical testing is performed in facilities to analyze and understand how a product (e.g., material, coating, paint, primer) will react in real world harsh corrosive environments. Subtropical testing is performed on HVAC units, marine vehicles, pad mounted equipment, paints, coatings, electrical and mechanical controls and many other types of equipment.
Subtropical testing is also known as subtropical exposure testing.
Corrosionpedia Explains Subtropical Testing
Subtropical test duration can be very long - up to nine years or more. The tests replicate worst case scenarios to determine how a product will behave when exposed to harsh corrosive environments.
Subtropical testing is performed in a Florida material research facility, which is the only commercial oceanfront facility for subtropical exposure testing in the United States and is rated as one of the most corrosive environments in the country.
Subtropical tests include:
- Atmospheric Exposure – This test examines how a product will perform under real world worst-case exposure conditions. In order to conduct this test, a wide array of fences and exposure racks are prepared per ASTM standards and the product is exposed at any angle or any position relative to the ground.
- Marine Submergence and Fouling Studies – This checks a product's reaction to a wide spectrum of fouling organisms, including barnacles, mollusks, calcareous tube worms, bryozoa, hydroids and algae.
