Standard Test Method for Wind Resistance of Concrete and Clay Roof Tiles (Air Permeability Method)

SIGNIFICANCE AND USE
5.1 The air permeability of roofing systems constructed from discrete elements, as is the case for clay and concrete tile and slate roof systems, is a critical factor in determining the wind resistance of the roof system. The ability of the roof system to relieve wind-induced uplift pressures as a result of the overall air permeability of the roof assembly relates to the resistance of the roof system to damage induced by wind.  
5.2 Natural wind conditions differ with respect to intensity, duration, and turbulence; these conditions are beyond the means of this test method to simulate.
SCOPE
1.1 The air permeability of tile roofing systems is a critical factor in determining the wind resistance of tile roofing as applied to a roof. This Standard describes a procedure for measuring the air permeability of clay and concrete tile and slate roof systems when applied to a small section of roof deck in accordance with the manufacturer's instructions.  
1.2 This test procedure measures the air permeability of a laid array of unsealed clay or concrete roof tiles or slates. The tiles or slates shall have a thickness between 1/8-in. (3-mm) and 2-in. (51-mm).  
1.3 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.  
1.4 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.  
1.5 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.

Standard Test Method for Wind Resistance of Concrete and Clay Roof Tiles (Wind Tunnel Method)

SIGNIFICANCE AND USE
4.1 It is known that the observed effects of wind simulated in a wind-tunnel apparatus are related to the effects observed from natural wind. The resistance of tiles to simulated wind in this test relates to the resistance of the tiles to the effects of natural wind when they are applied to a roof. One factor in the resistance of the tiles to the effects of both natural and simulated wind is the method of attachment specified in the manufacturer's instructions. This test method determines the uplift forces acting as a result of the simulated wind when tile are attached to a section of roof deck in accordance with the manufacturer's instructions. Natural wind conditions differ with respect to intensity, duration, and turbulence; these conditions are beyond the means of this test method to simulate.
SCOPE
1.1 This test method covers a procedure to determine the resistance of concrete and clay roof tiles to simulated wind effects in a wind-tunnel apparatus. Simulated wind velocities of 70 mph (31 m/s) to 130 mph (58 m/s) are employed.  
1.2 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.  
1.3 The text of this specification 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.  
1.4 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 Test Method for Wind Resistance of Concrete and Clay Roof Tiles (Mechanical Uplift Resistance Method)

SIGNIFICANCE AND USE
4.1 The method of attachment of roof tiles to the roof deck, or support structure, is one factor in the resistance of concrete and clay roof tiles to the action of wind. Several systems of attachment, and even combinations of systems, are used in the application of tile to a roof. The mechanical uplift resistance of the tile, when applied to the roof by any attachment system approved by, and in accordance with, the manufacturer's instructions, is a primary factor in the tile's resistance to the action of wind. This test method determines the mechanical uplift resistance that is related to resistance to the uplift forces acting as a result of wind. Natural wind conditions differ with respect to intensity, duration, and turbulence; these conditions are beyond the means of this test method to simulate.
SCOPE
1.1 This test method covers a procedure to determine the mechanical uplift resistance of concrete and clay roof tiles, which relates to the wind resistance of an air-permeable roof tile system as applied to a roof.  
1.2 The procedure covers mechanically-fastened attachment systems, adhesive-set attachment systems, and mortar-set attachment systems, or combinations of attachment systems, that are used to apply tile to a roof.  
1.3 The values stated in inch pound units are to be regarded as the standard. The values in parentheses are given for reference 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.

ASTM D7897-18(2023)(Practice)
Standard Practice for Laboratory Soiling and Weathering of Roofing Materials to Simulate Effects of Natural Exposure on Solar Reflectance and Thermal Emittance

SIGNIFICANCE AND USE
5.1 The solar reflectance of a building envelope surface affects surface temperature and near-surface ambient air temperature. Surfaces with low solar reflectance absorb a high fraction of the incoming solar energy. Sunlight absorbed by a roof or by other building envelope surfaces can be conducted into the building, increasing cooling load and decreasing heating load in a conditioned building, or raising indoor temperature in an unconditioned building. It can also warm the outside air by convection. Determination of solar reflectance can help designers and consumers choose appropriate materials for their buildings and communities.  
5.1.1 The solar reflectance of a new building envelope surface often changes within one to two years through deposition and retention of soot and dust; microbiological growth; exposure to sunlight, precipitation, and dew; and other processes of soiling and weathering. For example, light-colored “cool” envelope surfaces with high initial reflectance can experience substantial reflectance loss as they are covered with dark soiling agents. Current product rating programs require roofing manufacturers to report values of solar reflectance and thermal emittance measured after three years of natural exposure (2, 3). A rapid laboratory process for soiling and weathering that simulates the three-year-aged radiative properties of roof and other building envelope surface materials expedites the development, testing, and introduction to market of such products.  
5.2 Thermal emittance describes the efficiency with which a surface exchanges thermal radiation with its environment. High thermal emittance enhances the ability of a surface to stay cool in the sun. The thermal emittance of a bare metal surface is initially low, and often increases as it is soiled or oxidized (4). The thermal emittance of a typical non-metal surface is initially high, and remains high after soiling (5).  
5.3 This practice allows measurement of the solar reflectance a...
SCOPE
1.1 Practice D7897 applies to simulation of the effects of field exposure on the solar reflectance and thermal emittance of roof surface materials including but not limited to field-applied coatings, factory-applied coatings, single-ply membranes, modified bitumen products, shingles, tiles, and metal products. The solar reflectance and thermal emittance of roof surfacing materials can be changed by exposure to the outdoor environment. These changes are caused by three factors: deposition and retention of airborne pollutants, microbiological growth, and changes in physical or chemical properties. This practice applies to simulation of changes in solar reflectance and thermal emittance induced by deposition and retention of airborne pollutants and, to a limited extent, changes caused by microbiological growth.  
1.2 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.  
1.3 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 Test Method for Water Penetration of Metal Roof Panel Systems by Static Water Pressure Head

SIGNIFICANCE AND USE
5.1 This test method is a standard procedure for determining water leakage through metal roof panel system sideseams, endlaps, and roof plane penetrations when the roof system is subjected to a specified static water pressure head.
Note 2: In applying the results of tests by this method, note that the performance of a roof or its components or both, is in part a function of proper installation and adjustment. In service, the performance will also depend on the integrity of the supporting construction, roof slope, and on the resistance of components to deterioration by various causes: corrosive atmosphere, aging, ice, vibration, thermal cycling, etc. It is difficult to simulate the identical complex wetting, aging, and other variable conditions that can be encountered in service, including wind-blown ponded water; the effects of temperature and age on sealant performance; differential pressure across the joints due to wind, snow, and ice accumulation; densification and migration; and abrasions within the joint components which may occur during thermal cycling and other weather events. Some joint conditions are more sensitive than others to these factors.  
5.2 This test method will evaluate the resistance of roof panels, sideseams, endlaps, and roof plane penetrations to water submersion. It will not evaluate panel resistance to wind driven rain.
Note 3: See Test Method E1646 for a test which evaluates resistance to wind driven rain.  
5.3 This test method is not a structural adequacy test.  
5.4 This test method is applicable to single skin metal panels, the exterior skin of factory assembled composite panels, and the exterior skin of field assembled composite systems as long as means can be provided to distinguish leakage through the exterior panel sideseams/endlaps and perimeter leakage.
SCOPE
1.1 This laboratory test method covers the determination of the resistance to water penetration of exterior metal roof panel system sideseams, endlaps, and roof plane penetrations when a specified static water pressure head is applied to the outside face of the roof panel.
Note 1: This test method is intended to evaluate water-barrier (not water-shedding) roof system joints and details. These systems are also referred to as hydrostatic roof systems.  
1.2 This test method is limited to specimens in which the sideseams and attachments are clearly visible and in which the source of leakage is readily observable.  
1.3 This test method excludes performance at roof perimeter conditions.  
1.4 This test method is suitable for evaluating leakage at roof plane penetrations such as fasteners, curbs, pipes, and expansion joints under a static water pressure head.  
1.5 The proper use of this test method requires a knowledge of the principles of water pressure.  
1.6 The text of this standard includes notes and footnotes excluding tables and figures, which provide explanatory material. These notes and footnotes shall not be considered as requirements of the standard.  
1.7 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.  
1.8 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 precautionary statements, see Section 7.  
1.9 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.
