【国外标准】 Standard Test Methods for Detention Hollow Metal Vision Systems

4.1 A major concern for corrections administration officials is the resistance of security barriers used in detention/correctional facilities to certain types of physical attack that it is reasonable to expect in the field. These test methods are designed to aid in identifying a level of physical security for fixed detention hollow metal vision systems.4.2 These test methods are not intended to provide a measure of resistance for a vision system subjected to attack by corrosive agents, high-powered rifles, explosives, sawing, or other such methods. These test methods are intended to evaluate the resistance of a vision system to violent attacks using battering devices such as benches, bunks, fire extinguishers, or tables; hand guns up to and including the .44 magnum; and fires started by using mattresses, books, and similar flammable materials.4.3 The primary purpose or result of this standard is to provide detailed test methods that approximate the levels of abuse to which it is possible that vision systems become subjected in the field. The desired result of its use is to give assurance of protection to the public, to prison administrative personnel, and to the inmates themselves in the event of such attack.4.4 It is recommended that detention/correctional facility administration provide adequate training, supervision and preventative maintenance programs to enable door assemblies to function as intended throughout the expected service life.1.1 These test methods cover fixed detention hollow metal vision systems of various materials and types of construction. These fixed hollow metal vision systems are used in wall openings in detention and correctional institutions designed to incarcerate inmates.1.2 Frame assemblies investigated under these test methods include individual components including detention security hollow metal frames, frame anchoring, security glazing, panels, and removable glazing stops.1.3 These test methods are designed to test the capability of a fixed detention hollow metal vision system to prevent, delay, and frustrate escape; to limit or control access to unauthorized or secured areas; and prevent passage of contraband.1.4 These test methods apply primarily to detention hollow metal vision systems between secure areas generally found inside a detention/correctional facility such as: day rooms, control rooms, cells, and sally ports. These test methods are applicable to vision systems other than hollow metal, provided testing and reporting procedures are followed.1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
