【国外标准】 Standard Test Methods for Physical Assault on Overhead Horizontal Fixed Barriers for Detention and Correctional Facilities

4.1 A major concern for administrative officials is the security of barriers used in detention/correctional facilities. These test methods are designed to aid in identifying levels of physical security for horizontal fixed barriers, which serve to enclose or separate secure areas. This does not apply to the passage of contraband or vandalism.4.2 These test methods are not intended to provide a measure of resistance for a ceiling subjected to attack by corrosive agents, by high-powered rifles, explosives, sawing, or other such methods not typically available to inmates. These test methods are intended to evaluate the resistance of a ceiling to violent attacks by sustained manpower using battering devices, such as benches, barbells, bunks, or tables; and by an upward static force such that could be applied by an inmate pushing against the ceiling with his hands, feet, or back (that is, squat position on a top bunk in a cell). Attacks from outside the facility and fire resistance ratings are not addressed in this standard.4.3 The primary purpose or result of these test methods is to approximate the levels of abuse to which horizontal fixed barriers could possibly be subjected in the field. The desired result of its use is to help provide assurance of protection to the public, to facility personnel, and to the inmates themselves.4.4 It is recommended that detention/correctional facility administration provide adequate training, supervision, and preventive maintenance programs to enable horizontal fixed barriers to function as intended throughout the expected service life.1.1 These test methods cover requirements for simulated service tests and testing equipment for determining the performance characteristics of horizontal fixed barriers designed to incarcerate inmates in detention and correctional institutions. The testing equipment provides for the setup and testing of sample barriers and installation systems.1.2 It is the intent of these test methods to help ensure that detention security horizontal fixed barriers perform at or above minimum acceptable levels for control of passage to unauthorized or secure areas, to confine inmates, and to delay and frustrate escape attempts. Provide security grilles, access doors, light fixtures, and similar assemblies compatible with these levels of performance, with test apparatus adjustments as required to suit the particular product.1.3 These test methods apply to horizontal fixed barriers enclosing or separating secure areas of detention/correctional facilities.1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversion to SI units that are provided for information only and are not considered standard.1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.
