Susan Test is a method for measuring the impact sensitivity of explosives, in which the explosive charge is confined by a metallic shell and launched by a air-gun or propellent-gun with a speed of 30-300m·s-1 or more respectively. After traveled a distance of about 3.7m, the projectile impacts on a steel target. The principle procedure of the test is described in this paper. The flying velocity of the projectile is measured by a timekeeping system, which consists of two He-Ne lasers and two photoelectric converters....

Susan Test is a method for measuring the impact sensitivity of explosives, in which the explosive charge is confined by a metallic shell and launched by a air-gun or propellent-gun with a speed of 30-300m·s-1 or more respectively. After traveled a distance of about 3.7m, the projectile impacts on a steel target. The principle procedure of the test is described in this paper. The flying velocity of the projectile is measured by a timekeeping system, which consists of two He-Ne lasers and two photoelectric converters. The manner of the projectile impacted on the target, the deformation of the projectile caused by squeezing and compression, and the whole progress involving the ignition and explosion are recorded by a complete set of pulsed laser high speed schlieren photographic systen, which consists of a sequential pulsed Q-swithed ruby laser, a model 640 schlieren apparature. and an access type rotating mirror scanning high speed camera. A set of multiple senser-amplifier-transient waveform storage system is used to measure and record the superpressure of the air shock produced by the explosion. A Susan Test curve which represents the relationship between the velocity of the projectile and the relative energy release can be obtained from this test. The safety of some explosives, such as JO-9159. JOB-9003 and TNT/RPX 40/60 etc.. are e-valuated according to the results measured by Susan Test.

苏珊试验是测量炸药撞击感度的一种射弹试验。将炸药装入壳体中,用空气炮或火炮以30~300m/s,甚至更高的速度发射,弹丸约经3.7m,与钢靶相撞。本文简介了试验的基本方法,用氦氖激光器、接收转换器、测时仪构成的光电系统测量弹丸的飞行速度;用红宝石序列脉冲激光器、纹影仪以及等待型转镜扫描相机构成的高速摄影系统拍摄弹丸的着靶姿态以及撞靶后挤压变形直至点火爆炸的全过程;用传感器、电荷放大器、瞬态波形存贮器构成的数据采集系统测量炸药爆炸后形成的空气冲击波超压。试验得到弹丸撞靶速度与相对释放能关系的苏珊感度曲线。本文给出了JO-9159、JOB-9003以及TNT/RDX 40/60等几种炸药的试验结果,对其安全性能作出了初步评价。

This paper describes the test for metal jet to penetrate and initiate the explosive. Metal jet is generated from the standard shaped charge which has 40 mm diameter. 66 mm height and a copper liner of 60° apex angle with 36 mm base diameter. Shaped charge is RDX/WAX, 95/5. density 1. 680±0. 005 Mg/m3. Its maximum penetration is 150±6mm of 45# steel target at a fixed stand-off distance. After penetrating various thickness of steel target the velocity and its diameter of the metal jet are measured by a 2MV flash...

This paper describes the test for metal jet to penetrate and initiate the explosive. Metal jet is generated from the standard shaped charge which has 40 mm diameter. 66 mm height and a copper liner of 60° apex angle with 36 mm base diameter. Shaped charge is RDX/WAX, 95/5. density 1. 680±0. 005 Mg/m3. Its maximum penetration is 150±6mm of 45# steel target at a fixed stand-off distance. After penetrating various thickness of steel target the velocity and its diameter of the metal jet are measured by a 2MV flash X-ray system. The curve relationship between the jet velocity and the steel target thickness is calibrated. And its fit formula is obtained. The sensitivity of the explosive to be tested is expressed in terms of the critical thickness of the steel target which gives a 50 per cent probability of detonation of the explosive. The critical velocity and diameter of the metal jet relating to the critical thickness of the steel target can be obtained by means of above mentioned curve or formula. The jet sensitivity of TNT. Comp. B and TATB is presented. Finally the results are discussed.

本文描述了聚能金属射流侵彻起爆炸药的试验装置和方法。聚能金属射流是用标准空心装药产生的,空心装药的尺寸为直径40mm,高度66mm,药型罩为紫铜,顶角60°,底直径36mm,壁厚0.75mm,炸药为钝化黑索今,密度1.680±0.005Mg/m~3。炸高为72mm时的最大穿深为150±6mm45~#钢靶柱。用2MV脉冲闪光X射线摄影仪测量了金属射流穿透不同厚度的钢靶板后的头部运动速度及直径,作出了射流头部速度对钢靶板厚度的标定曲线及拟合曲线公式。炸药对射流侵彻起爆的感度,采用使炸药产生50%概率爆轰的钢靶板厚度(即临界厚度)表示,相对应的临界的流速度可用标定曲线或拟合公式求得。文中给出了TNT.Comp.B及TATB炸药的射流侵彻起爆感度.最后对结果进行了讨论。

Terms and definitions of 20 industrial explosives in USSR are given.Classification of industrial explosives at various times are tabulated.It can be seen that the higher the safety properties required for coal mine permissible explosives,the more detailed in classification.Finally,testing methods of industrial explosives in USSR are given.
