Submit Handcuffs for Testing (NIJ Standard - 0307.01)

To ensure that the metallic handcuffs used by law enforcement and corrections agencies meet minimum performance requirements specified by criminal justice practitioners, the National Institute of Justice (NIJ), through the Law Enforcement Standards Office (OLES), developed a national voluntary minimum performance standard for metallic handcuffs (NIJ Standard-0307.01, PDF). This standard specified requirements for user information, markings, workmanship, weight, dimensions, mechanical strength, salt spray corrosion resistance and cheek-plate tamper resistance.

A voluntary compliance testing program was administered for many years by the National Law Enforcement and Corrections Technology Center-National (NLECTC-National), which has now transitioned to the Justice Technology Information Center (JTIC). Models that were submitted to the CTP were tested at independent laboratories approved by NIJ, and those models that were tested through NLECTC-National's testing program and found to comply with all the requirements of the standard are listed on NLECTC's Metallic Handcuff Consumer Product List (CPL).

New Standard

NIJ recently published Criminal Justice Restraints Standard 1001.00 (PDF). This is a voluntary performance standard for restraints for use by the criminal justice community. It addresses wrist-to-wrist and ankle-to-ankle restraints, defines performance requirements, and outlines methods used to test performance. The standard also includes additional restraints technology. Single use restraints as well as nonmetallic and high security restraints are addressed.

NIJ is currently exploring transitioning conformity assessment of restraints in accordance with this new standard to accredited certification bodies in the private sector.  Manufacturers interested in having their products tested for conformance to the new standard are advised to contact NIJ for more information, as the previous metallic handcuffs CTP is being phased out.
