本标准规定了对防弹材料及产品的弹道极限V50进行评价的技术要求、试验方法，V50值计算与修正、试验报告的编写等。
射击试验中，如果第一发射击穿透(或阻断)，第二发的装药量应在第一发的基础上减少(或增加)约30m／s速度的药量，以得到一发阻断(或穿透)。
在有效命中射击中，若试样的试验混合速度差小于等于88 m／s，则以小于等于38 m／s的评价速度差，取不少于三发最高阻断速度和三发最低穿透速度结果相反、数量对等的至少六发测点弹速，求算术平均值，记为试样测点；值，由i值修正计算得到试样V50值。
V50值应由测点i值按照下列公式计算：V50一口e一
试样在试验前应按GB／T 1446--2005的规定进行状态调节。
This standard specifies the technical requirements, test methods, calculation and correction of V50 value, and compilation of test reports for evaluating the ballistic limit V50 of ballistic materials and products.
During the shooting test, if the first shot is a perforation (or stop), the charge for the second shot shall be reduced (or increased) by approximately 30 m/s in velocity relative to the first shot, to obtain a stop (or perforation).
In effective hits, if the test cross velocity of the sample is less than or equal to 88 m/s, then with an evaluating velocity range less than or equal to 38 m/s, take at least three highest stop velocities and three lowest perforation velocities with opposite results and equal numbers, totaling at least six measured point velocities, calculate the arithmetic mean, record it as the sample measured point value, and calculate the sample V50 value by correction from the value.
The V50 value shall be calculated from the measured point value using the following formula: V50 = v e^(-ax).
The sample shall be conditioned before testing in accordance with GB/T 1446-2005.
