What is On-Site EPR Measurements - DoS Testing Services at Element?

On-site EPR measurements and DoS testing evaluate the degree of sensitization in materials using non-destructive methods. At Element, we utilize the Double Loop Electrochemical Potentiokinetic Reactivation (DL-EPR) test method to assess susceptibility to intergranular corrosion and polythionic acid stress corrosion cracking. Our testing is performed directly at your facility, providing rapid results without material destruction.
