<P>PROBLEM TO BE SOLVED: To provide a cold and hot impact testing machine and a method for cold and hot impact testing, capable of preventing samples from dispersing even if powerful cold blast and hot blast are supplied, while suppressing an increase of the cost to the minimum. Ž<P>SOLUTION: The cold and hot impact testing machine 100, which applies high-temperature and low-temperature cold impacts to a sample, includes: an input means 24 for inputting a condition temperature of high and low temperatures; a hot blast supplying means 21 for supplying the hot blast whose temperature is adjusted to the high temperature of the condition temperature; a cold blast supplying means 22 for supplying the cold blast whose temperature is adjusted to the low temperature of the condition temperature; a first test tank 1 equipped with a supply port for supplying the cold blast and the hot blast; a second test tank 2 which is disposed in the first test tank 1 in a nested fashion and has an openable/closable slit 18 at a position where the cold blast and the hot blast are blocked by a chassis 12; a temperature sensor 15 for detecting a temperature of the second test tank 2; and an aperture control means 31 which brings the slit 18 being in its closed state to open so as to have a prescribed aperture A, when the temperature reaches a first reference temperature, and which brings the slit 18 to open so as to have an aperture B larger than the aperture A, when the temperature reaches a second reference temperature.
