· The calibration data were obtained by performing a number of "no-target" ballistic tests. The projectiles used for these calibration tests were 2.8 g blunt aluminium cylinders, 46 mm in length. The ELVS was used to measure the motion of the projectile. A voltage–time curve for one of the "no-target" calibration tests is shown in Fig. 3.

· radiographs are used to measure projectile residual velocity. These post penetration radiographs were used in either orthogonal or in-line configuration depending on the test configuration and taken at different times for velocity measurements. The x-ray system is a Scandiflash model XT-150 with soft x-ray and short pulse options installed.
Ballistics Testing. Ballistics testing is a critical component of the QA processes associated with MIL-STD-810 and other regulatory guidelines. At NTS, we have more than 50 years of experience helping defense contractors meet these challenges while developing more effective tools and technologies for America's troops.
· Ballistics is defined as the study and science of projectiles and firearms. Ballistics testing is a standards-based process where products are tested to determine if they meet protection, safety and performance criteria. Most …
· 10.4: Ballistic Galvanometer and the Measurement of Magnetic Field. A galvanometer is similar to a sensitive ammeter, differing mainly in that when no current passes through the meter, the needle is in the middle of the dial rather than at the left hand end. A galvanometer is used not so much to measure a current, but rather to detect whether ...

· These target properties are used to gauge magnetic "quality" and therefore will require measurement at one or more points in the supply chain. Table 1 illustrates the most common equipment/method used for each. Table 1: Key magnetic figures of merit and methods of measurement Figure of Merit Abbreviated Description Measurement Method
Ballistic training involves the use of jumps, throws, or strikes to continually accelerate throughout the concentric action, and should not be confused with plyometrics. This form of training can be used with light, moderate, and/or heavy loads and it seems that it is the intent to move quickly, rather than the actual velocity of the load, that ...
· Magnetic Tests at Low Inductions and Audio Frequencies: These tests are usually made on Epstein apparatus specimens by employing the A.C. bridge method. The simple inductance bridge may be used, or a modification of Owen's bridge or the induced m.m.f. may be measured with a co-ordinate A.C. potentiometers.
