The objective of this paper is to describe the design, construction and testing of a low cost chamber for accelerated aging of polymers that meets a low and high ultraviolet radiation cycle on the test specimens in accordance with ASTM G154. The methodology was based on the survey of the standards related to the tests of accelerated aging of polymers and of the existing equipment, providing the subsidies for the development of the project, which was validated by the construction and evaluation of its performance. The camera control is performed by an Arduino-based electronic system and uses commercially available components that meet project specifications. The equipment met the requirements for both the specifications and the low cost and will integrate the laboratories of the University of Mogi das Cruzes (UMC), Villa-Lobos campus, to carry out tests on polymer materials.
