Abstract

An apparatus having a circulation type coolant sprayer attached for conducting low temperature pyro tests, according to the present invention, makes an extreme low-temperature, high-cycle pyro test possible in a short time by means of a rotation bending pyro test apparatus having a high test speed. The present invention relates to a low temperature pyro test apparatus having a circulation type coolant sprayer attached and comprising: a rotation bending test unit which grasps and fixes each of both ends of a test piece using a pair of rotating bodies, and connects one side of each rotating body to a weight so as to bias same toward the test piece and induce rotation bending of the test piece; and a coolant circulating unit which, prior to the rotation bending of the test piece, continuously circulates and pours coolant on the test piece until a lamp ON state is reached.
