Corrosive Test Data From NASA
(Test Bed & KSC Report)
The Atmospheric Exposure Site (Kennedy Space Center,
FL.) was established in the 1960s and has been cited as the most
corrosive atmospheric corrosion test site in the United States.
It is located at latitude 28.7ÿN, longitude 80.6ÿW, and
approximately 100 feet from the high tide line. Over the years
thousands of coated test panels, stress corrosion cracking
specimens, and commercially produced components have been
evaluated in the high salt, high humidity, high UV Florida
seacoast environment.

The site has approximately 600 feet of front row
exposure for atmospheric corrosion specimens. Many types
of test samples can be accommodated, including standard
size test coupons (4Ó x 6Ó), stress corrosion cracking
specimens, and full-scale test articles. These
experiments can be performed in either a boldly exposed
or sheltered configuration. Both power and data
connections are available within the site to power tests
articles and record on board data instrumentation
outputs.
