The National Institute of Justice (NIJ) plans to facilitate the development of baseline performance requirements and standardized test methods, including certification requirements, for equipment used by U.S. law enforcement civil disturbance units (CDUs). NIJ anticipates that these standards will be developed through a consensus process through one or more accredited standards development organizations with the participation of U.S. law enforcement CDU practitioner subject matter experts, testing laboratories, and product certifiers as well as manufacturers and industry. For U.S. law enforcement agencies planning to procure new or certified CDU personal protective equipment, NIJ has identified either British Standard 7971 or standards developed by the UK Home Office as performance standards that may meet agencies' needs until U.S. standards can be developed.
