5.1 Test Method F2656/F2656M states that variable-width barriers shall be tested in minimum- and maximum-width configurations. Interpolations between maximum and minimums are allowed if there are no structural modifications made to the barrier (that is, all structural components, including spacing of support members and connections, are similar between the two barriers tested at minimum and maximum widths). Extrapolation outside of the tested minimum- and maximum-width configurations is not allowed.5.2 However, there is a class of barriers such as some nets and fences that rely on a structurally repetitive interior system and strengthened end terminals or anchorages that are not explicitly treated under Test Method F2656/F2656M. There are situations where the interior system of the barrier could be exceptionally long and it is impractical or impossible to test the maximum-width configuration due to test facility site constraints, as an example.5.3 When a variable-width barrier is dependent on a structurally repetitive interior system that could be exceptionally long and terminated with strengthened end terminals, this practice shall be used to establish the maximum-width configuration that is equivalent to an infinitely long barrier.5.4 This practice shall be used with Test Method F2656/F2656M to establish a condition designation and penetration rating for the complete variable-width barrier. Knowing the condition designation and penetration rating provides the ability to select an appropriate barrier for site-specific conditions around a facility.5.5 Use of this practice assumes:5.5.1 Except for the instrumented end terminations, the structurally repetitive interior system is constructed and installed in a manner that represents the proposed actual service installation;5.5.2 Except for the instrumented end terminations, the structurally repetitive interior system conforms to supplier specifications and drawings;5.5.3 The actual service installation of the structurally repetitive interior system shall be terminated using the strengthened end terminals used for the minimum-width configuration test; and5.5.4 The instrumented end terminations used for the maximum-width configuration shall provide axial load resistance only.1.1 This practice provides a procedure for applying Test Method F2656/F2656M test criteria to an exceptionally long (that is, 300 ft [91 m] or greater) variable-width vehicle barrier as defined by Test Method F2656/F2656M.1.2 This practice provides a procedure to establish a maximum-width configuration that is equivalent to an infinitely long barrier for a variable-width barrier as defined by Test Method F2656/F2656M.1.3 This practice applies only to variable-width barriers that are dependent on both a structurally repetitive interior system that could be exceptionally long and terminated with strengthened end terminals.1.4 This practice applies only when it is impractical or impossible to install the maximum-width test article of a variable-width barrier because the test facility site constraints limit the practical length of the test article.1.5 This practice does not apply when its use is employed solely with the intent of reducing the test article installation cost when it is practical to test the maximum-width installation length.1.6 This practice does not apply to continuous or other types of vehicle barriers.1.7 This practice shall be used with Test Method F2656/F2656M to establish a condition designation and penetration rating for the complete variable-width barrier. Further, the complete variable-width barrier shall receive a single penetration rating that is determined as the maximum penetration rating for both the minimum- and maximum-width configurations tested, and is taken to be the final penetration rating. The penetration rating is not based on engineering calculation or judgment.1.8 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.9 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.1.10 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.

4.1 As the building industry shifts towards performance-based design, specification of material properties consistent with anticipated in-service conditions becomes paramount to the design process. When specifying water vapor transmission properties, it is important to identify water vapor transmission properties for WRB/AB products that are measured under test conditions relevant to anticipated in-service conditions. This guide provides a performance-based framework for characterizing the water vapor transmission properties of WRB/AB.4.2 When specifying WRB/AB, water vapor permeance is an important attribute to consider for proper moisture management and functioning of wall and roof assemblies in service. In North America, water vapor transmission properties of water-resistive and air barrier materials are traditionally tested in accordance with Test Methods E96/E96M. This guide adopts the ASTM E96/E96M test methods as a primary source of information for water vapor transmission properties of WRB/AB unless otherwise instructed by the design professional.4.3 Most standard test methods rely on a limited set of steady-state testing conditions for evaluating the water vapor transmission properties of materials. Test conditions used to measure and report water vapor transmission values of WRB/AB should represent the in-service conditions of the tested material as closely as possible (that is, should cover the range of temperature and relative humidity conditions the products will experience when installed in wall and roof assemblies). The water vapor permeance of many WRB/AB materials can vary by more than an order of magnitude when tested for ranges of temperatures and relative humidity expected in service. For this reason, WVT properties over the full range of environmental conditions that the material will most likely experience in service should be used or evaluated when specifying a material or assembly design for a specific project.1.1 This document provides guidelines for specifying water vapor transmission (WVT) properties for above-grade water-resistive barriers and air barriers (WRB/AB), typically installed between building structural components and cladding that compose the exterior side of building envelopes in North America.1.2 This guide applies to all types of water-resistive barrier and air barrier products, including multifunctional products, regardless of the manufacturing process, type of material, or installation technique.1.3 This guide provides general provisions for specifying and reporting the water vapor transmission properties of WRB/AB determined by standardized test methods, in accordance with in-service conditions these products typically experience within building envelopes.1.4 It is beyond the scope of this guide to optimize the water vapor transmission characteristics of WRB/AB for specific conditions of use. The specific conditions of use should account for variations in indoor and outdoor climates, cladding type, moisture storage capacity of cladding materials, thermal insulating measures for wall and roof assemblies, air movement, and vapor diffusion control strategies.1.5 This guide does not address proper installation and integration of WRB/AB with other wall and roof components.1.6 The values stated in inch-pound units are to be regarded separately as standard. Within the text, the SI units shown in parentheses are provided for information only. The values stated in each system are not exact equivalents; therefore, each system shall be used independently. Combining values from two systems may result in non-conformance with the standard. However, derived results can be converted between systems using appropriate conversion factors (see Table 1).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.

1.1 This specification is limited to vapor permeable flexible sheet materials which are intended to be mechanically attached and are generally installed behind the cladding system in exterior walls.1.2 This specification is limited to the evaluation of materials and does not address installed performance. Although the fastening practices (type of fastener, fastening schedule, etc.) may affect the installed function of these materials, they are not included in this specification.1.3 This specification does not address integration of the water-resistive barrier with other wall elements. The topic is addressed in more detail in Practice E2112 and Guide E2266.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.

The capabilities of individual components are not part of this specific test method's Conditions of Compliance.5.3 In this test method, the test specimens are subjected to one or more specific test conditions. When different test conditions are substituted or the end-use conditions are changed, it is not always possible by, or from, this test method to predict changes to the characteristics measured.5.4 This test method is not intended to be used as the only test method in the selection of a perimeter fire barrier. It is not intended as a specification for all attributes required by a perimeter fire barrier, or any of its individual components, in order for a perimeter fire barrier to be used in a particular application.1.1 This test method measures the performance of the perimeter fire barrier and its ability to maintain a seal to prevent fire spread during the deflection and deformation of the exterior wall assembly and floor assembly during the fire test, while resisting fire exposure from an interior compartment fire as well as from the flame plume emitted from the window burner below. The end point of the fire-resistance test is the period of time elapsing before the first condition of compliance is reached as the perimeter fire barrier is subjected to a time-temperature fire exposure.1.2 The fire exposure conditions used are those specified by this test method for the first 30 min of exposure and then conform to the Test Methods E119 time-temperature curve for the remainder of the test in the test room.1.3 This test method specifies the heating conditions, methods of test, and criteria for evaluation of the ability of a perimeter fire barrier to maintain the fire resistance where a floor and exterior wall assembly are juxtaposed to a perimeter joint.1.4 Test results establish the performance of perimeter fire barriers during the fire-exposure period and shall not be construed as having determined the suitability of perimeter fire barriers for use after that exposure.1.5 This test method does not provide quantitative information about the perimeter fire barrier relative to the rate of leakage of smoke or gases or both. While it requires that such phenomena be noted and reported when describing the general behavior of perimeter fire barrier during the fire-resistance test, such phenomena are not part of the conditions of compliance.1.6 Potentially important factors and fire characteristics not addressed by this test method include, but are not limited to:1.6.1 The performance of the perimeter fire barrier constructed with components other than those tested, and1.6.2 The cyclic movement capabilities of perimeter fire barriers other than the cycling conditions tested.1.7 This test method is used to measure and describe the response of materials, products or assemblies to heat and flame under controlled conditions but does not by itself incorporate all factors required for the fire-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire conditions.1.8 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.9 The text of this test method references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.1.10 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.1.11 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.

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 walls which enclose or separate secure areas. This does not apply to the passage of contraband.4.2 These test methods are not intended to provide a measure of resistance for a wall subjected to attack by corrosive agents, by high-powered rifles, explosives, sawing, or other such methods. These test methods are intended to evaluate the resistance of a wall to violent attacks by sustained manpower using battering devices, such as benches, bunks, or tables, and by handguns up to and including .44 magnum. Attacks from the outside 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 walls will potentially be subjected in the field. The desired result of its use is to help provide assurance of protection to the public, to facility administrative personnel, and to the inmates themselves.4.4 It is recommended that detention/correctional facility administration provide adequate training, supervision, and preventative maintenance programs to enable walls 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 walls designed to incarcerate inmates in detention and correctional institutions. The testing equipment provides for the setup and testing of two sample fixed barriers side-by-side, one with no openings and one equipped with a representative penetration in accordance with the American Correctional Association (ACA) standard for clear view area of 3 ft2 (0.279 m2), 12 in. (305 mm) wide by 36 in. (914 mm) high.1.2 It is the intent of these test methods to help ensure that detention security walls perform at or above minimum acceptable levels to control passage of unauthorized or secure areas, to confine inmates, to delay and frustrate escape attempts, and to resist vandalism. It is recognized that in order to meet the intent of these test methods, opening assemblies within these walls must be compatible with the level of performance required by: Test Methods F1450, F1592, and F1643.1.3 These test methods apply to walls enclosing or separating secure areas of detention/correctional facilities.1.4 The values stated in inch-pound units are to be regarded as the standard. The SI values given in parentheses are approximate and for information only.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.
