Solar air thermal collectors are one of the technologies used to improve the efficiency of fresh air heating system in building spaces. Solar air collectors have the advantage of preventing freezing and overheating problems when compared with solar water collectors. However, thus far, there have been no harmonized thermal performance test facilities or round robin tests (RRT) based on the international standard ISO 9806 in Korea. In this study, an ISO 9806 thermal performance test facility was introduced and designed. In addition, an RRT was conducted based on ISO 9806 and compared to RRT sample Exova performance test results to verify the consistency of the thermal performance. The thermal efficiency ranged 36.06% ~ 72.02% depending on a change flow rate change of 36.6 ~ 182.9 m3/(hr·m2), respectively. The RRT was successfully conducted to compare the results of the Exova thermal performance test. A comparison between the Exova and KIER tests showed a relative error of 5.51% and 6.42% for ambient wind velocities of 1.0 and 1.8 m/s, respectively.
