The WES BLASTX code was recently revised Version 3 to predict the airblast and thermal effects of large explosions in small rooms. This paper compares the results of internal gas pressureexternal shock calculations against measured data from tests in large-scale and small-scale underground magazines. Comparison of calculated and measured internal blast pressures indicate that the code tends to wider-predict internal gas pressure. In most cases, however, the BLASTX3 code provides good predictions of the general level of internal and external airblast effects.
