The latest results, still preliminary, of tests dedicated to study the performance of Resistive Plate Chamber for the CMS experiment are presented. Full efficiency with a 2 ns time resolution in conditions of incident flux up to 2 kHz/cm2 has been obtained. Detector uniformity has been studied and found to be well within the constraints due to the large surfaces used in the experiment. An aging test is currently being carried out and shows no significant performance variation with time.
