The NIST Standard Bullets and Casings Project
Abstract
The National Institute of Standards and Technology (NIST) standard bullets and casings project will provide support to firearm examiners and to the National Integrated Ballistics Information Network (NIBIN) in the United States. The standard bullet is designed as both a virtual and a physical bullet signature standard. The virtual standard is a set of six digitized bullet signatures originally profiled from six master bullets fired at the Bureau of Alcohol, Tobacco and Firearms (ATF) and the Federal Bureau of Investigation (FBI). By using the virtual signature standard to control the tool path on a numerically controlled diamond turning machine, 40 standard bullets were produced. Based on the NIST proposed parameter and algorithm, a bullet signature measurement system was established for bullet signature measurements of the standard bullets. Initial measurement results showed high reproducibility for both the measurement system and the standard bullets. A traceability scheme has been proposed to establish the measurement traceability for nationwide bullet signature measurements to NIST, ATF and FBI. Prototype standard casings have also been developed. Keywords: Ballistics, Bullet Signature, Reference Material, RM, Standard Bullet, Standard Casing, Traceability
Brief Biography
Jun-Feng Song is a Research Engineer and a Project Leader at the National Institute of Standards and Technology. He is also a Postdoctoral Research Adviser for the National Research Council of the US National Academies. In 1981, he received a MS degree in Mechanical Engineering from the Harbin Institute of Technology, China. Before he came to NIST in 1987, he invented and patented the random profile roughness specimens. In 1995, these specimens were included in both the ASME and ISO standards. In 1994, he proposed a metrology approach to unifying the international Rockwell C hardness measurements. He is currently the project leader for NIST standard bullets and casings. He published two books and more than 70 papers. He received a NIST Bronze Medal Award in 1994, a NIST E. B. Rosa Award in 1997, and a NIST Judson C. French Award in 2002.
