Corrosion Testing

LTL performs Stress Corrosion Cracking Analysis per ASTM C692. This testing covers the influence that various thermal insulations have on the tendency to cause external stress corrosion cracking (ESCC) of austenitic stainless steels as the result of leachable corrodants.

Stress Corrosion Cracking Test Stand
Stress Corrosion Cracking Specimen 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 a period of 28 days after which the specimens are inspected for cracking.

Other Corrosion Testing Service Include:

  • Chemical Analysis of thermal Insulation Materials per ASTM C871 for the presence of leachable corrodants.
  • Corrosion Testing to ASTM A262
  • Environmental Humidity Testing
  • Salt Spray Testing
