01 · UNDERSTAND THE SERVICE
Overview
Corrosion testing is an environmental simulation that helps you estimate component service life, compare candidate materials, and evaluate coating durability through accelerated testing methods.
Sterling performs daily compliance checks, and corrosion appearance is evaluated after testing. Test duration varies by specification and by the material's resistance.

ANSWERS FOR ENGINEERS
Frequently Asked Questions
Which corrosion standards does Sterling test to?
We test to ASTM B 117, ASTM G 85, ASTM B 368 (CASS), and ISO 9227, among other environmental methods.
What coatings and finishes can you evaluate?
Phosphated surfaces, painted metals, organic coatings, electroplating (zinc, chromium, nickel, copper, tin), zinc flake coatings, and hot-dip galvanized coatings with paint overlays.
How long does a corrosion test run?
Duration varies by specification and by the material's corrosion resistance; corrosion appearance is evaluated after testing.
