This document is a voluntary performance standard for restraints for use by the criminal justice community. It addresses only wrist to wrist and ankle to ankle restraints. This standard defines both performance requirements and the methods used to test performance. In order for a manufacturer, supplier or other entity to claim that a particular restraint model satisfies this NIJ standard, the model must be in compliance with this standard, as determined in accordance with this document and the associated forthcoming document, Criminal Justice Restraints Certification Program Requirements, NIJ CR-1001.00. Both this standard and the associated certification program requirements document are produced as a part of the Standards and Testing Program of the U.S. Department of Justice, Office of Justice Programs, National Institute of Justice, as is a third forthcoming associated document, Criminal Justice Restrains Selection and Application Guide, NIJ Guide-1001.00.
