The real scale fire suppression test inside a road tunnel were carried out for water spray systems. The dimension of the tunnel is 7.5m in height and 11.6m in width. 3 different water spray nozzle systems with low operating pressure less than 3.5 bar were used in the experiment. Two types of fires were tested. One is a <TEX>$1.4m^2$</TEX> heptane pool fire and the other is a 2000CC passenger car fire. From the experiment, the spray densities of tested systems were about <TEX>$6.0\;l/min/m^2$</TEX> which is currunt domestic guideline. Although all the systems cannot extinguish the tested fires, it was found that they can reduce the tunnel temperature and have a capability to control and suppress the tested fire.
