(Test Method)Standard Test Method for Wind Resistance of Concrete and Clay Roof Tiles (Mechanical Uplift Resistance Method)
Standard Test Method for Wind Resistance of Concrete and Clay Roof Tiles (Mechanical Uplift Resistance Method)
SIGNIFICANCE AND USE
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 and health practices and determine the applicability of regulatory limitations prior to use.
