Computer-based solutions offer enhanced efficacy and ease of automation in every walk of life. Computer-based systems for real time monitoring and control of corrosion testing equipment provide significantly improved measurement precision as well as a basis for improved accuracy in data acquisition for complex tests. This paper discusses one such system called a Constant Extension Rate Tester (CERT) used to automate slow strain rate (SSR) testing. SSR testing is an effective means to assess material susceptibility to environmentally assisted cracking (EAC) in corrosive systems.
