Abstract
A hydrogen embrittlement tester, for a metal sample, has a vise device for holding the sample. For testing bend fracture, the distance between both ends of the sample is measured, which corresponds to that of the distance between the sample holding members. For testing the delayed fracture, the time from when the sample is held until it is fractured is measured. An electric path is formed between the sample holding members and the sample only when the sample is held so that measurement can be automatically stopped when the sample is fractured.
