Artificially promoted tester for fastness to light

Abstract

Abstract PURPOSE:To maintain a sample consistantly at a fixed temperature by forming an air feed chamber below a testing chamber demarcated therefrom and closing a lower communication port for communicating the chamber to the discharge side of a variable capacity type blower. CONSTITUTION:A relatively broad air feed chamber 3 is formed below a testing chamber 1 and demarcated with a wall 2 and communicated to the discharge side of a variable capacity type blower 4 while the air intake side thereof 4 is communicated to an air conditioning equipment 5 comprising a humidifier and a heater. Then, an appropriate amount of air adjusted in the temperature and humidity is sent into the air feed chamber 3 according to the set capacity of the blower 4. An air feed cylinder 6 is provided on the top of the air feed chamber 3 communicating thereto and a lower communication port 6a is closed with a metal screen or a porous plate such as punching board. This can maintain a sample consistently at a fixed temperature.
