ASTM F1915-05(2019)

4.1 The predictable and reliable performance of detention glazing used in detention and correctional facilities is a major concern. These test methods aid in assigning a level of physical security to glazing used in window and door assemblies based upon objective tests which can be consistently duplicated.

4.2 These test methods identify four security grades, corresponding to the four security grades established in Test Methods F1450. The intent is to establish a comparable level of performance for opening assemblies which incorporate detention glazing in conjunction with window and door assemblies. Test methods for detention glazing differ in sequencing a variety of attack tools and temperatures.

4.3 These test methods evaluate the resistance of detention glazing to attacks using blunt and sharp impact devices and fire. These test methods evaluate the performance of glazing in hot and cold environments. These test methods do not provide a measure of the resistance or performance of glazing subjected to attack by ballistics, chemical agents, explosives or other extreme methods of attack. Where such elements are a factor, consult the manufacturer.

4.4 The primary purpose of these test methods is to approximate the levels of abuse and operating conditions to which detention glazing is subjected in detention and correctional institutions. The desired result of these test methods is to provide a measure of assurance of protection to the correctional personnel, public, and inmates.

4.5 Detention and correctional facility administrative staff are encouraged to provide adequate training, supervision, and preventative maintenance programs to enable detention glazing assemblies to function as intended.

1.1 These test methods, including a fire test response method, cover the apparatus, procedures, and acceptance conditions for evaluating the normal operational performance and the performance characteristics under assault conditions of detention glazing used in window and door assemblies in detention and correctional facilities; thus, these test methods only give an indication of the performance characteristics of detention glazing in actual service. Such variables as installation and maintenance conditions are not considered except as otherwise included in this test method.

1.2 It is the intent of these test methods to help ensure that detention glazing performs at or above minimum acceptable levels to restrict inmate passage to unauthorized areas, to confine inmates, to delay and frustrate escape attempts and to resist vandalism.

1.3 Tools defined in these test methods are representative of similar tools or materials, which may become available to inmates within the secure perimeter of detention and correctional facilities, and which could be used to inflict similar product damage.

1.4 These test methods should not be used to establish or confirm the absolute prevention of forced entries or exits. These test methods define five factors (tool, temperature, techniques, time, and number of impacts) used to determine resistance to defined attacks.

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

1.6 In these test methods, the specimens are subjected to one or more specific sets of laboratory test conditions. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from these test methods to predict changes in the physical attack, or fire-test-response characteristics measured, or both; therefore, the results are valid only for the physical attack, or fire-test-exposure conditions, or both, described in these test methods.

1.7 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.

1.8 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.
