Results are reported from a programme of work undertaken by the UK Health and Safety Executive to investigate the airblast produced by commercial sector explosives having velocities of detonation (VoD) in the range 2000-8200 m s(-1). The data produced will be useful in evaluating the blast hazards of such explosives in industrial circumstances and also as a means of assessing post-accident damage. All of the solid explosive materials studied produced blast waves which ramped up into shock-wave form close to the point of initiation. The dependence of peak overpressure and positive phase impulse on scaled distance is presented and compared to that of TNT. The TNT equivalence (TNT(e)) technique is shown to be applicable to solid phase explosives with a wide range of VoD, although the precise values of TNT(e) vary with distance.
英国健康与安全执行局开展了一项工作项目，旨在研究商业领域中爆速（VoD）在2000 - 8200米/秒范围内的炸药所产生的空气冲击波，本文报告了该项目的结果。所产生的数据将有助于评估此类炸药在工业环境中的爆炸危害，也可作为评估事故后损害的一种手段。所有研究的固体炸药材料产生的冲击波在起爆点附近都会上升为冲击波形式。给出了峰值超压和正相冲量与比例距离的关系，并与TNT的关系进行了比较。结果表明，TNT当量（TNT(e)）技术适用于爆速范围广泛的固相炸药，不过TNT(e)的精确值会随距离而变化。
