The National Institute of Justice has released Public Safety Bomb Suit Standard 0117.01, a May 2016 update to the existing NIJ bomb suit standard. This standard was developed by a panel of practitioners, technical experts and others with experience in standards development and conformity assessment. This document is a voluntary performance standard for bomb suits for use by certified public safety bomb technicians while performing render safe procedures and disposal activities. It defines both performance requirements and the methods used to test performance. The standard addresses six key areas: fragmentation, impact, flame, some blast overpressure, optics and ergonomics.
