A Resistive Plate Chamber (RPC) module of size 15cm×15cm has been developed and its performance tested in a cosmic ray setup. Performances have been tested using three different gas compositions using P-10 and Freon-134A at different bias voltages. A characteristic plateau region has been obtained for efficiency when measured with varying applied bias voltage. The maximum efficiency is obtained 92% and the performance is found to be stable.
