... Induced Stress Cracking (HISC) has been demonstrated by constant load testing of specimens polarized to -1050 mV SCE . For the cold worked material Slow Strain Rate Testing (SSRT) at Test Level VI in NACE MR0175 / ISO 15156, a condition within Type 4d is discussed. With its high mechanical strength...

For investigations under compressed conditions, the compression set was determined for specimens of ACM, FKM and HNBR after exposure in heating oil B0 and B20 for 3,7,14, 28, 56 and 90 days at 40 °C according to ISO 815-1. It was found that the resistance in B20 at 40 °C was given for all...

... Abstract The DCB method is a crack arrest test, i.e., the specimen is self-loaded with a wedge and the constant displacement configuration makes the SIF decrease as the crack grows. Thus, K ISSC provided from the DCB test could be different from the toughness of a cracked structure under...
