4.1 A major concern for detention and correctional administrative officials is the reliable operation of sliding devices used in their facilities. These test methods aid in assigning a level of physical security and performance to devices for sliding door assemblies.4.2 These test methods evaluate the resistance of a sliding door assembly to attacks using battering devices, prying devices, smoke, and fire. These test methods also evaluate the performance of a sliding device under simulated operating conditions. These test methods do not provide a measure of the resistance or performance of the device subjected to attack by chemical agents, ballistics, explosives, or other extreme methods of attack. These test methods do not measure the resistance or performance of the device when subjected to environmental elements such as humidity, temperature, rain, snow, or wind-carried dust or sand. Where such elements may be a factor the manufacturer should be consulted for proper application.4.3 The primary purpose of these test methods is to approximate the levels of abuse and operating conditions to which devices are subjected in detention and correctional institutions. The result of these test methods will provide a measure of assurance of protection to the correctional personnel, public, and inmates.4.4 Preventative maintenance programs shall be provided in accordance with the manufacturer's recommendation to enable sliding device assemblies to function as intended throughout the expected service life.4.5 These test methods do not measure the performance or cycle life of the local or remote mechanical emergency release mechanism, or both, due to their design variables and low user requirements.1.1 These test methods cover the apparatus, procedures, and acceptance conditions for evaluating the normal operational performance and the performance characteristics under assault, smoke, and fire conditions of sliding device assemblies in detention and correctional institutions. These test methods give an indication of the performance characteristics of devices in actual service. Such variables as installation and maintenance conditions are not considered.1.2 It is the intent of these test methods to help ensure that detention sliding devices perform at or above minimum acceptable levels to control passage to unauthorized or secure areas, to confine inmates and to delay and frustrate escape attempts and resist vandalism. However, these test methods do not address door construction. It is recognized that in order to meet the intent of these test methods, door assemblies shall be compatible with the level of performance required by Test Methods F1450.1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.1.4 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.1.5 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.

5.1 Due to hydraulic pressure that may be present on some applications, engineers need to understand the capability of these products to resist this pressure. This test allows engineers to compare products and verify pullout strength.5.2 Hydraulic pullout resistance is a function of locking extension dimensions, locking extension geometry, locking extensions per area, locking extension polymer composition, and the properties of the concrete in which the locking extensions are embedded.5.3 The data from this test method provides comparative information for rating hydraulic pullout resistance of different geomembranes with locking extensions embedded in concrete. Hydraulic pullout resistance, while partly dependent on locking extension dimensions, has no simple correlation to locking extension dimensions and geometry. Hence, hydraulic pullout resistance cannot be determined with a small sample without potentially producing misleading data to the actual hydraulic pullout resistance of the material. Therefore, the hydraulic pullout resistance is expressed in kPa (lb/ft2).5.4 The apparatus can be circular or square in nature and must have a test area of 0.36 m2 (558 in.2).5.5 Fig. 1 shows an example of a circular test apparatus that can be used in the performance of this test. The apparatus requires a pressure vessel rated to a minimum 690 kPa (14 410 lb/ft2). The vessel test diameter should be a minimum of 677.04 mm (26.655 in.) as shown in Fig. 1.FIG. 1 Picture of Circular Test ApparatusNOTE 1: Larger vessels may be used but it is up to user to establish correlation to the standard size vessel. The use of a smaller diameter vessel than denoted in this standard may contribute to higher pullout resistance due to thickness or stiffness of some products.5.6 Test Pedestal—The base of the testing apparatus which holds the test specimen.5.7 Upper Flange—Is the flange that is bolted down on top of specimen to create a seal.5.8 Form—Is an aluminum ring used to form test specimen as shown in Fig. 2.FIG. 2 Bottom of Form with Studs Facing Up and Cylinder Spacer5.9 Specimen Ring—The solid ring that is placed around test specimen to contain leakage through the concrete.5.10 The vessel will have a system to measure pressure.5.10.1 The system for measuring pressure shall be capable of being read to an accuracy of 3.5 kPa (0.5 psi).5.11 Concrete shall be a ready-mixed concrete per Specification C94/C94M with a minimum cured compressive strength of 34 473.8 kPa (5 000 psi).NOTE 2: Alternate concrete or grout mixtures may be used for project-specific applications with the approval of the owner or engineer.5.12 All tests shall be conducted at standard laboratory temperatures of 23 ± 2 °C (73.4 ± 3.6 °F).1.1 This test method covers the determination of the hydraulic pullout resistance of a geomembrane with locking extensions embedded in concrete by determining the pressure required for locking extensions of the embedded specimen to pullout of the concrete.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only and are not considered standard.1.3 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.1.4 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.
