4.1 A major concern for detention and correctional administrative officials is the reliable operation of hinges used in their facilities. These test methods aid in assigning a level of physical security and performance to hinges for swinging door assemblies.

4.2 These test methods evaluate the effect on hinges of battering attacks on the door simulating assault conditions as well. These test methods also evaluate the performance of a hinge under simulated normal operation. These test methods do not provide a measure of the resistance or performance of a hinge to attack by the following: chemical agents, ballistics, explosives, or other extreme methods of attack, such as direct impact or manipulation on the hinges or to environmental elements such as rain, snow, or wind-carried dust or sand. Where such elements are a potential factor, consult the manufacturer.

4.3 The primary purpose of these test methods is to approximate the levels of abuse conditions and normal operating conditions to which hinges are subjected in detention and correctional institutions. These test methods attempt to do this through the different grade levels associated with cycle and impact testing. The desired result of these test methods will provide a measure of assurance of protection to the correctional personnel, public, and inmates.

1.1 These test methods cover the apparatus, procedures, and acceptance conditions for evaluating the normal operating performance characteristics and the performance characteristics under assault conditions of hinges used in swinging door assemblies in detention and correctional institutions. These types of hinges are described in detail in 3.1.6, 3.1.9, and 3.1.22. Thus, these test methods only give an indication of the performance characteristics of hinges in actual service. Such variables as installation and maintenance conditions which have a potential impact on performance characteristics are not considered.

1.2 It is the intent of these test methods to help ensure that detention hinges (reference to hinges is inclusive of a continuous hinge) perform at or above minimum acceptable levels to confine inmates, to delay and frustrate escape attempts, and to resist vandalism and assault conditions. It is recognized that in order to meet the intent of these test methods, door, frame and lock assemblies must be compatible with the level of performance required by Test Methods F1450 and F1577.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.

1.4 Consult NFPA 80 for Fire Doors & Windows concerning hinge requirements on fire doors.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 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.
