Fig. 11-1 General view of testing units for IASCC tests

For IASCC initiation tests, a UCL specimen 1.5 mm in diameter is used to shorten the time from crack initiation to specimen rupture. A detection mechanism is enclosed in a metal bellows.For IASCC growth tests, the crack growth is monitored using a DCPD method to improve the accuracy of crack length measurement.
