    Abstract

    A new experimental technique has been developed for running stress corrosion cracking tests on insulating materials. The new technique uses a steam heated pipe for heating the coupons and uses an “upside down” dripping action rather than a “wicking” action, as in ASTM Evaluating the Influence of Wicking-Type Thermal Insulations on the Stress Corrosion Cracking Tendency of Austenitic Stainless Steel (C 692). In addition to providing a more realistic approach, the new procedure correlates well with the old, simplifies sample coupon preparation and gives added reliability to the test results.
