A new method EN 17096 was developed by CEN TC189 to determine the resistance against slow crack growth by a tensile test performed at 80°C. The slope of such a tensile curve above its natural draw ratio (e.g. strain hardening modulus) correlates with the measured failure times determined by SP-NCTL tests. Very good correlation between strain hardening modulus and failure times in single-point NCTL tests were found. This webinar goes through the background of EN 17096 and discuss the test method and the details.
