How to read this table
Each row gives the system, the test, the result, the standard and the source. A result applies to the conditions of that test — its substrate, film thickness and failure criterion — and should only be compared with results measured the same way.

Where do the results come from?
They are quoted from the coating data sheets, with the standard each test was run to. Ask us for the data sheet of the system you are considering.
Can I get a test run on my own coil?
Yes. Salt spray and heat-transfer tests on your coil geometry can be arranged; new salt spray tests take several weeks.
