Standard Test Methods for Deglazing Force of Fenestration Products

Standard Test Methods for Deglazing Force of Fenestration Products

SIGNIFICANCE AND USE
4.1 Under normal usage, deglazing loads are generally applied parallel to the plane of the glazing material and eccentric to the sash element when it is opened, closed, or lifted out of the frame. When operating hardware is present, torsional forces may be increased. Opening and closing forces are normally applied from the interior side only. Sliding glass door panels are activated from both sides.  
4.2 The ability of fenestration products to resist deglazing forces may vary with a number of factors. These factors should be considered when selecting test specimens or when interpreting test results. Bedding compounds in newly assembled sashes may not reach full strength until they have been allowed to cure for several days or weeks. Some sash materials are subject to shrinkage at low temperatures and increased elasticity at high temperatures. Therefore, a sash containing these materials may exhibit a range of deglazing resistance due to varying temperature conditions. Normal manufacturing tolerances and clearances in sash members and glazing materials may also affect deglazing resistance. Further, although fenestration products are designed to operate within certain force limits, improper installation, wear, and abuse may increase the forces necessary for sash operation.  
4.3 When determining which members of a given sash shall be tested for deglazing resistance, consideration must be given to the manner in which the sash may be operated when normally installed. Handles and lift devices are usually located on the sash for the convenience of the operator and therefore dictate the normal direction of operation.  
4.4 Test Method A presents a technique for actual measurement of the deglazing forces of an individual sash member.  
4.5 Test Method B presents a technique for measuring the deglazing force of two opposite members. This test method is intended for quality control measurements.
SCOPE
1.1 These test methods measure the resistance of elements of fenestration products such as operating (or removable) window sashes, storm sashes, and sliding glass door panels (hereafter referred to as sash members) to forces tending to deglaze the construction.  
1.2 These test methods utilize concentrated loads applied to the interior side of a sash member in a manner simulating normal opening and closing forces. Removable sashes are loaded to simulate handling for removal and cleaning.  
1.3 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.  
1.4 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.

Standard Practice for Determining the Effects of Temperature Cycling on Fenestration Products

SIGNIFICANCE AND USE
5.1 Fenestration products, when exposed to differential temperatures (constant higher or lower temperatures on the exterior and room temperature on the interior), or temperature cycling (relatively constant room temperature on the interior and repeated cycling of higher and lower temperatures on the exterior), will have stresses induced on components that may cause failure or changes in overall system performance. Some of these changes may be temporary, with their effects on system performance lasting only during the cyclical temperature exposure. Other changes may be more permanent because of the failure of critical components or irreversible changes in those critical components that control overall system performance.  
5.2 In this practice, a procedure is provided for evaluating the effects of exposure to temperature cycling at standardized conditions on fenestration products. It is useful for product evaluation and development. Interrelationships between window components can be studied under laboratory conditions simulating in-service temperature extremes.  
5.3 Laboratory approximation of in-service temperature cycling and temperature extremes is a useful tool for the fenestration designer. These conditions help in evaluating designs and components for absolute and relative interactions on overall performance when these products are installed and functioning in residential and commercial buildings.  
5.4 This practice is limited to temperature exposure and temperature cycling only. Temperature is only one of many environmental factors that affect field performance of fenestration products. Products made with different materials or construction methods may show specific sensitivity to different environmental factors, such as humidity, ultraviolet radiation, or airborne chemicals.  
5.5 Because of the complexity and cost of a single apparatus capable of measuring window performance, providing temperature cycling, and providing infrared radiation exposure, mo...
SCOPE
1.1 This practice covers the testing of any fenestration products that are installed with the exterior surface exposed to weathering conditions. It is intended to measure the response of the fenestration product to temperature cycles with the temperature changes being induced by controlling the air temperature on the exterior (weather side) or by exposing the product to infrared radiation, or both. When tested using this practice, fenestration products are exposed to standard cycles of elevated and depressed ambient air and surface temperatures. Test methods are specified for evaluating changes in performance that may occur as a result of temperature cycling. With this practice, seasonal and diurnal temperature conditions are simulated in a controlled laboratory apparatus.  
1.2 In this practice, two test methods, Test Method A and Test Method B, are described for exposing the exterior surface of fenestration products to the elevated portion of a standardized temperature cycle. The purpose for providing two test methods of exposure is to address two distinct needs of the fenestration industry.  
1.2.1 Test Method A uses infrared radiation to increase the surface temperature of the fenestration product and uses a black panel temperature sensor placed in front of the specimen's exterior surface to sense the temperature. The surface temperature of the black panel temperature sensor is raised to a preset level above the exterior ambient air temperature. This provides a more realistic test for temperature exposure based on atmospheric solar radiation and its effect on the temperature increase of exterior building materials. This method should be used when the number of cycles can be large and the outcome is critical for field correlation. Test Method A is intended for comparative product evaluations.  
1.2.2 Test Method B uses elevated temperature produced by convective hot air to achieve the exterior air temperature set-p...

ASTM F842-17(2023)(Test Method)
Standard Test Methods for Measuring the Forced Entry Resistance of Sliding Door Assemblies, Excluding Glazing Impact

SIGNIFICANCE AND USE
5.1 These test methods are intended to establish a measure of resistance for sliding door assemblies subjected to attacks (other than impacting glazing materials) by unskilled or opportunistic burglars. Resistance to higher levels of force generated by skilled burglary attack requires methods, such as alarms, communication, or apprehension systems, or special security glazing materials more sophisticated than those evaluated by these test methods. Technicians performing the test should understand the intent of this test method and should be trained on the execution and pass/fail criteria.  
5.2 Entry through a sliding door assembly can be accomplished by impacting or removing glazing materials. This method does not evaluate glazing materials for breakage or de-glazing. Other standards must be used to evaluate forced entry by impacting or removing glazing.  
5.3 Acceptance criteria for performance levels are a matter for authorities having specific jurisdiction to establish. Suggested guidelines are found in Annex A1.
SCOPE
1.1 These test methods determine the ability of sliding door assemblies to restrain, delay, or frustrate forced entry.  
1.2 For purposes of these test methods, sliding door assemblies are defined as described in 1.2.1 – 1.2.4 and as shown in Fig. 1. Sliding door assemblies with a combination of operable panels and fixed panels (lites) shall be classified and tested separately for each type.
FIG. 1 Typical Horizontal Sliding Door Assembly Types (viewed from the exterior)  
1.2.1 Type A—A sliding door assembly which incorporates one or more sliding panels that lock to the jamb.  
1.2.2 Type B—A sliding door assembly which incorporates one or more sliding panels that lock to an intermediate jamb.  
1.2.3 Type C—A sliding door assembly which incorporates one or more sliding panels that abut and lock to other panels.  
1.2.4 Type D—A sliding door assembly which incorporates one or more fixed or stationary panels that are designed not to open.

Standard Practice for Installation of Exterior Windows, Doors and Skylights

SIGNIFICANCE AND USE
4.1 This practice recognizes that the effective performance of installed fenestration products is dependent in part upon following proper installation procedures and appropriate workmanship.  
4.2 This practice recognizes that the coordination of trades and proper sequencing are essential for effective fenestration installation. The general contractor shall be responsible for the necessary coordination of trades and proper construction sequencing of the installed fenestration product.  
4.3 Improper installation of units contributes to excessive air, water and sound leakage, and condensation. It may promote the deterioration of wall constructions, insulation, fenestration products, and their respective finishes.  
4.4 This practice presumes a working knowledge of applicable federal, state, and local codes and regulations, specifically, but not limited to required means of egress, requirements for safety glazing materials, and structural requirements of applicable codes.  
4.5 This practice presumes a working knowledge of the tools, equipment, and methods necessary for the installation of specified fenestration products. It further assumes familiarity with flashing and sealing, glazing procedures, finishes where applicable, and an understanding of the fundamentals of construction that affect the installation of these units.  
4.6 This practice presumes that the products that have been furnished for the installation and their locations within the structure comply with all the applicable building codes and regulations.
SCOPE
1.1 This practice covers the installation of fenestration products in new and existing construction. For the purpose of this practice, fenestration products shall be limited to windows, sliding patio-type doors, swinging patio type doors, and skylights, as used primarily in residential and light commercial buildings.  
1.2 This practice assumes that the installer possesses basic woodworking skills and an understanding of wall and roof construction, sheet metal work, and joint sealant practices.  
1.3 This practice attempts to instruct and familiarize the installer with the concepts of both Barrier Systems and Membrane/Drainage Systems, in order to ensure the continuity of the building envelope. This practice attempts to educate the installer, builder, architect, and other users in the identification and understanding of the water shedding system of the building envelope.  
1.4 This practice covers the installation process from pre-installation procedures through post-installation procedures, for single units or factory-mulled multiple units in a single opening. It does not cover the fabrication or assembly of multiple units, whether such fabrication takes place in a factory or at the intended installation site. The installer should check with the manufacturer of factory-assembled units for instructions for anchoring. When using field-mulled units, follow manufacturer's recommendations and make certain that they meet applicable codes. This practice does not cover the selection of appropriate fenestration products for a given application, nor the selection of other products or systems for use in the installation.  
1.5 This practice provides minimum requirements that will help to accomplish the installation of fenestration products in an effective manner. Actual conditions in buildings vary greatly and, in some cases, substantial additional precautions may be required. In the event that the manufacturer's installation instructions provided with the product conflict with requirements of this practice, the manufacturer's instructions shall prevail. This practice is not intended to limit or exclude other new procedures that may refine or further improve the effectiveness of fenestration installation.  
1.5.1 This practice is intended to be used for background information in order to develop training manuals and training programs. Further, this practice attempts to cons...

ASTM E331-00(2023)(Test Method)
Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform Static Air Pressure Difference

SIGNIFICANCE AND USE
5.1 This test method is a standard procedure for determining the resistance to water penetration under uniform static air pressure differences. The air-pressure differences acting across a building envelope vary greatly. These factors should be fully considered prior to specifying the test pressure difference to be used.
Note 1: In applying the results of tests by this test method, note that the performance of a wall or its components, or both, may be a function of proper installation and adjustment. In service, the performance will also depend on the rigidity of supporting construction and on the resistance of components to deterioration by various causes, vibration, thermal expansion and contraction, etc. It is difficult to simulate the identical complex wetting conditions that can be encountered in service, with large wind-blown water drops, increasing water drop impact pressures with increasing wind velocity, and lateral or upward moving air and water. Some designs are more sensitive than others to this upward moving water.
Note 2: This test method does not identify unobservable liquid water which may penetrate into the test specimen.
SCOPE
1.1 This test method covers the determination of the resistance of exterior windows, curtain walls, skylights, and doors to water penetration when water is applied to the outdoor face and exposed edges simultaneously with a uniform static air pressure at the outdoor face higher than the pressure at the indoor face.  
1.2 This test method is applicable to any curtain-wall area or to windows, skylights, or doors alone.  
1.3 This test method addresses water penetration through a manufactured assembly. Water that penetrates the assembly, but does not result in a failure as defined herein, may have adverse effects on the performance of contained materials such as sealants and insulating or laminated glass. This test method does not address these issues.  
1.4 The proper use of this test method requires a knowledge of the principles of pressure measurement.  
1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.6 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. For specific hazard statements, see 7.1.  
1.7 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.

ASTM E2268-04(2023)(Test Method)
Standard Test Method for Water Penetration of Exterior Windows, Skylights, and Doors by Rapid Pulsed Air Pressure Difference

SIGNIFICANCE AND USE
5.1 This test method is a standard procedure for determining the resistance to water penetration during rapid cyclic pulses of dynamic air pressure differences. The air-pressure differences acting across a building envelope vary greatly. These factors should be fully considered prior to specifying the test pressure difference to be used.  
5.2 The median test pressure used in this test method is defined as the specified test pressure supplied by the user and related to the maximum positive building design pressure. This test method departs from the format of other ASTM water penetration resistance test methods based on a maximum test pressure related to a maximum positive building design pressure.  
5.3 As the specified or median test pressure is increased, the maximum test pressure in this procedure is also increased to 1.5 times the specification median test pressure. This higher maximum test pressure may not be representative of actual building service conditions. For this reason the maximum recommended median test pressure is 480 Pa (10 psf), which corresponds to a maximum test pressure of 720 Pa (15 psf).  
5.4 The pulsed pressure of this test method may act to pump water past dry seals and breather systems of units incorporating these features, thereby making the test method more severe than a static pressure test method. On the other hand, the low pressure portions of the pressure cycles of this test method may allow weep systems and drainage dams to dissipate water from units incorporating these features, thereby making the test method less severe than a static pressure test method.
Note 1: In applying the results of tests by this test method, note that the performance of a wall or its components, or both, may be a function of proper installation and adjustment. In service, the performance will also depend on the rigidity of supporting construction and on the resistance of components to deterioration by various causes, (vibration, thermal expansion and ...
SCOPE
1.1 This test method covers the determination of the resistance of exterior windows, skylights, and doors to water penetration when water is applied to the outdoor face and exposed edges simultaneously with a rapid pulsed air pressure at the outdoor face higher than the pressure at the indoor face.  
1.2 This test method is applicable to windows, skylights, or doors alone. Those interested in testing curtain walls to rapid pulsed air pressure differences should use AAMA 501.1-94.  
1.3 This test method addresses water penetration through a manufactured assembly. Water that penetrates the assembly, but does not result in a failure as defined herein, may have adverse effects on the performance of contained materials such as sealants and insulating or laminated glass. This test method does not address these issues.  
1.4 The proper use of this test method requires a knowledge of the principles of pressure measurement.

Standard Practice for Determining the Acoustical Performance of Windows, Doors, Skylight, and Glazed Wall Systems

SIGNIFICANCE AND USE
4.1 Air Leakage Relative to Sound Transmission—Certain frequencies are more susceptible to sound transmission through cavities or discontinuities in the test specimen; therefore, the air leakage of the test specimen is reported to allow the approving authority information relative to air tightness.
Note 1: The AAMA/WDMA/CSA 101/I.S.2/A440 document provides air leakage acceptance criteria for these products based on their performance class. Acoustical products could require a lower air leakage rate than what is required in this standard in order to achieve the desired acoustical performance.  
4.2 Operating Force Relative to Sound Transmission—The use of specific sealing components to achieve a given sound rating could affect operating force of the vertical or horizontal sliding sash or panels of the assembly; therefore, operating force is reported to allow the approving authority information relative to sash or panel operating forces.
Note 2: The opening force in 28 CFR Part 36 ADA for interior hinged doors and sliding doors is limited to 5 lbf (22.2 N). The AAMA/WDMA/CSA 101/I.S.2/A440 document provides operating force acceptance criteria for products based on their performance class.  
4.3 Latching Force Relative to Sound Transmission—Latching force can affect the compression of seals and the amount of damping applied to the system that in turn affects the air leakage and the acoustical performance. The use of specific sealing components and latching/locking hardware can affect the force required to close and latch the door under test. The latching force is reported to allow the approving authority information relative to sash or panel latching conditions.
Note 3: The AAMA/WDMA/CSA 101/I.S.2/A440 document states that the maximum force to latch shall be measured and reported.
SCOPE
1.1 This practice establishes requirements for testing and rating acoustical performance of window, door, skylight, and glazed wall systems, regardless of their method or materials of manufacture.  
1.1.1 Operating force, latching force, and air leakage are integral elements of the acoustical performance of window, door, skylight, and glazed wall systems. This practice requires (when applicable) the concurrent testing of operating force, latching force, and air leakage, in addition to the sound transmission loss test.  
1.2 This practice establishes the test methodology, specimen criteria, and classification rating system for purposes of determining the acoustical performance levels of window, door, skylight, and glazed wall systems only, and not through openings between such assemblies and adjacent construction.  
1.3 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.  
1.4 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.

ASTM E1105-15(2023)(Test Method)
Standard Test Method for Field Determination of Water Penetration of Installed Exterior Windows, Skylights, Doors, and Curtain Walls, by Uniform or Cyclic Static Air Pressure Difference

SIGNIFICANCE AND USE
5.1 This test method is a standard procedure for determining the resistance to water penetration under uniform or cyclic static air pressure differences of installed exterior windows, skylights, curtain walls, and doors. The air-pressure differences acting across a building envelope vary greatly. These factors should be considered fully prior to specifying the test pressure difference to be used.
Note 1: In applying the results of tests by this test method, note that the performance of a wall or its components, or both, may be a function of proper installation and adjustment. In service, the performance will also depend on the rigidity of supporting construction and on the resistance of components to deterioration by various causes, vibration, thermal expansion and contraction, and so forth. It is difficult to simulate the identical complex wetting conditions that can be encountered in service, with large wind-blown water drops, increasing water drop impact pressures with increasing wind velocity, and lateral or upward moving air and water. Some designs are more sensitive than others to this upward moving water.
Note 2: This test method does not identify unobservable liquid water which may penetrate into the test specimen.  
5.2 Laboratory tests are designed to give an indication of the performance of an assembly. Field performance may vary from laboratory performance since the supporting structure for the test specimen, methods of mounting, and sealing in the laboratory can only simulate the actual conditions that will exist in the building. Shipping, handling, installation, acts of subsequent trades, aging, and other environmental conditions all may have an adverse effect upon the performance of the installed product. This field test procedure provides a means for determining the performance of a product once installed in the building.  
5.3 The field test may be made at the time the window, skylight, curtain-wall, or door assemblies are initially installed ...
SCOPE
1.1 This test method covers the determination of the resistance of installed exterior windows, curtain walls, skylights, and doors to water penetration when water is applied to the outdoor face and exposed edges simultaneously with a static air pressure at the outdoor face higher than the pressure at the indoor face.  
1.2 This test method is applicable to any curtain-wall area or to windows, skylights, or doors alone. It is intended primarily for determining the resistance to water penetration through such assemblies for compliance with specified performance criteria, but it may also be used to determine the resistance to penetration through the joints between the assemblies and the adjacent construction. Other procedures may be appropriate to identify sources of leakage.  
1.3 This test method addresses water penetration through a manufactured assembly. Water that penetrates the assembly, but does not result in a failure as defined herein, may have adverse effects on the performance of contained materials such as sealants and insulating or laminated glass. This test method does not address these issues.  
1.4 The proper use of this test method requires a knowledge of the principles of pressure measurement.  
1.5 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.  
1.6 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. For specific hazard statements, see 7.1.

Standard Test Method for Determining the Rate of Air Leakage Through Exterior Windows, Skylights, Curtain Walls, and Doors Under Specified Pressure and Temperature Differences Across the Specimen

SIGNIFICANCE AND USE
5.1 The exterior building envelope and its components (for example, windows and doors) separate the interior conditioned spaces from exterior environmental factors such as heat, cold, rain, wind, noise dust, etc. Building materials and components can expand or contract to varying degrees, depending on seasonal and diurnal exterior ambient air temperatures. Fluctuations in the ambient air temperatures can alter the sealing characteristics of windows, curtain walls, and doors by changing weather seal compression ratios. Thermal expansion or contraction of framing materials coupled with thermal blowing due to temperature gradients through the product, and alterations in the effective leakage areas due to weather seal shrinkage and compression set, can also significantly alter the air leakage rates of these products in field service applications. Air leakage tests performed using Test Method E283 (a laboratory air leakage test performed at ambient temperature conditions) will not account accurately for changes in air leakage rates that may occur from dimensional changes in fenestration systems, materials, and components.  
5.2 It is recommended that test specifiers consult the manufacturer for recommended test temperature extremes.  
5.3 This procedure provides a means for evaluating air leakage rates of fenestration systems under various temperature and pressure conditions and air flow directions. It is also applicable for use in evaluating the efficiency of weather sealing products in fenestration systems. All air flow rates are converted to standard conditions to provide a means of comparison between measurements made at different ambient air temperature and pressure conditions.  
5.4 Air leakage rates are sometimes used for comparison purposes. Such comparisons may not be valid unless the components being tested and compared are of essentially the same size, configuration, and design.
SCOPE
1.1 This test method provides a standard laboratory procedure for determining the air leakage rates of exterior windows, curtain walls, and doors under specified differential air temperature and pressure conditions across the specimen.  
1.2 Specified temperature and pressure conditions are representative of those that may be encountered at the exterior thermal envelope of buildings, excluding the effects of heat buildup due to solar radiation.  
1.3 This laboratory procedure is applicable to exterior windows, curtain walls, and doors and is intended to measure only such leakage associated with the assembly and not the installation; however, the test method can be adapted for the latter purpose.  
1.4 This is a laboratory procedure for testing at differential temperature conditions. Persons interested in a laboratory test at ambient conditions should reference Test Method E283. Persons interested in a field test on installed windows and doors should reference Test Method E783.  
1.5 Persons using this procedure should be knowledgeable in the areas of heat transfer, fluid mechanics, and instrumentation practices, and shall have a general understanding of fenestration products and components.  
1.6 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
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. For specific hazard statements, see Section 7.
