Why Corrosion Testing? Objectives, Costs and Applications
Written and reviewed by: Michel Comtois, M. Sc. (Physical Chemistry) and Anne-Marie Comtois, Eng. — August 1, 2026
Corrosion testing helps manufacturers evaluate how materials, coatings, and finished products respond to corrosive environments. It can be used to compare materials, verify protective systems, support quality control, investigate failures, and evaluate performance against specifications. Because corrosion behaviour depends on many interacting factors, the test method should reflect the material, application, service environment, and purpose of the evaluation.
