Corrosion Testing

Environmental degradation of materials related to corrosion accounts for $280 billion dollars per year in damage to metallic structures. Our proven testing protocols and analysis can help prevent failure resulting from exposure to harsh environments.

Lehigh Testing Laboratories performs stress corrosion cracking analysis per ASTM C692. This testing determines how much influence various thermal insulations have on the tendency to cause external stress corrosion cracking (ESCC) of austenitic stainless steels as the result of leachable corrodents.

ASTM C692 Details

The test is performed by placing a pre-stressed specimen on a heated test fixture covered with the subject insulation. A controlled amount of distilled or deionized water is then applied for 28 days, after which the specimens are inspected for cracking.

Additional Testing Methods

Lehigh Testing Laboratories also offers chemical analysis of thermal insulation materials per ASTM C871 in its New Castle, Delaware, labs. It is useful for detecting the presence of leachable corrodents. Other corrosion testing services that we offer include the following:
