An improvised explosive device is regarded as one of the primary threats that can cause fatalities to armoured vehicle occupants. Upon detonation, the shock wave injures the crews as they are in direct contact with the blast impact through their feet and seating position. It is crucial to disperse the shock wave within a short time thus reducing the potential injury towards the vehicle's occupants. Traditional experimental processes typically use an actual vehicle and specialised anthropometric test dummy which is costly and non-repeatable if the asset is damaged during tests. This paper presents a scaleddown blast testing approach which comprises of an instrumented general-purpose dummy and a blast capsule. The capsule was designed to accommodate dummy at different seating position and a recumbent position. The main structural component of the blast capsule was designed and analysed using the strength of materials principle. Accelerometers were installed on specific areaof the blast capsule and an instrumented dummy for data measurement. The blast testing was performed using PE4 and at a fixed standoff distance under the capsule hull. Results have shown that the measured data have similarity in terms of shock history curves with other published works. Results obtained can also be used in validation of future simulation work.
