Abstract : Blast wave data for all past field tests have been reviewed. Some previously unused gage data of sufficiently good quality for determining dynamic pressure impulse have been found and the data reduced. Dynamic pressure impulse has been inferred from tank displacement data using the curve of dynamic pressure impulse versus displacement as a calibration curve (with the tank playing the role of a gage). This allowed extension of dynamic pressure impulse results to higher values than previously available and also provided data points at additional scaled burst heights. Following this, Height of Burst Charts, i.e. , iso-scaled dynamic pressure impulse contours in the scaled height of burst -- scaled ground range plane, were constructed using the totality of the useable dynamic pressure impulse data. The charts, are for two cases: Near-Ideal -- Lightly/Moderate Dust and Near-Ideal -- Moderate/Heavy Dust. The former is the better determined of the two. It is believed that these charts are the most accurate obtainable from the totality of all existent blast wave measurements.
