Abstract: The described technology can quantitatively evaluate a material embrittlement behavior under various gaseous hydrogen environments (temperature and pressure). The described technology may include a small-punch test device allowing a specimen to be fixed inside a jig comprising upper and lower dies, gas to be filled at the lower part of the specimen, and a punch for applying force to be included at the upper part thereof so as to bend the specimen in a vertical downward direction under an environment of the influent gas and measure the same. The small-punch test device also includes an insulating container provided so as to encompass the jig therein and a temperature measuring device connected to the inside of the insulating container so as to measure the internal temperature of the insulating container and the temperature of the specimen. The small-punch test device further includes a heat transfer device transferring heat to the specimen.
