              This standard establishes requirements and methods for testing helmets and face shields to be worn by law enforcement officers during civil disturbances, riots, or other situations that pose a threat from blows to the head.
          Abstract
              The standard covers riot helmets and face shields of one class and is intended to assist law enforcement agencies in the selection of such equipment. The tests measure the ability of the equipment to resist penetration and to attenuate shock. Riot helmet requirements and tests cover peripheral vision, impact attenuation, penetration resistance, retention system, construction, and labeling. Face shield requirements and tests encompass light transmission, prismatic power, refractive power, resolving power, impact protection, and the fastening system. Diagrams, figures, and six references are provided.
