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.


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.
