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

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.
5. Apparatus
5.1 The test assembly of tiles attached to a section of roof deck is identical to that used in Test Method C1568 (Mechanical
Uplift Method) except that tile are not fitted with a load-transfer device.
5.2 The test assembly of tiles attached to the roof deck section is positioned on the floor of the wind tunnel apparatus as shown
in Fig. 1.
6. Conditioning
6.1 See the conditioning specified in Test Method C1568 (Mechanical Uplift Method) for each specific installation system being
investigated.
7. Procedure
7.1 Install the tile in the same manner as on a roof, in accordance with the manufacturer’s instructions, on a small section of
roof deck constructed to fit within the wind tunnel apparatus. The rafters shall be capable of being securely anchored to the floor
of the wind tunnel apparatus, and the sheathing firmly nailed to the rafters. Roofing underlayment is installed on top of the
sheathing and, if required, battens are nailed to the sheathing. The tile, underlayment system, and roof deck section constitute the
test assembly.
7.2 The test assembly for the tile installation system being investigated shall be installed in the floor of the wind tunnel apparatus
to cover area B in Fig. 1. Area A shall be used to provide the boundary conditions for the flow over Area B. The tiles in Area A
shall be firmly fixed to the floor of the wind tunnel apparatus. The tiles along the side of the test assembly shall be sealed with
adhesive tape to prevent air flow between the underside of the tiles and the slow moving layer of air on the floor of the wind tunnel.
Roof sheathing shall have at least one transverse joint in the test assembly to simulate air leakage from within the building.
7.3 When testing Hip and Ridge tiles, they shall be assembled on the test deck in the same manner that they would be applied
to a roof in accordance with the manufacturer’s instructions.
7.4 Specimens shall be tested at a surface temperature of 750°F (210°C) plus or minus 50°F (30°C) measured with a surface
mounted thermocouple and recorded on a chart to confirm th
