ASTM C1569-22

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: C1569 − 03 (Reapproved 2016) C1569 − 22
Standard Test Method for
Wind Resistance of Concrete and Clay Roof Tiles (Wind
Tunnel Method)
This standard is issued under the fixed designation C1569; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. 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 safety, health, and healthenvironmental 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.

NOTE 1—This standard is based on the International Code Council’s ICC/SBCCI SSTD 11 Test Standard for Determining Wind Resistance of Concrete
or Clay Roof Tiles, and work derived from the tile industry’s testing programs completed in the Redland Wind Tunnel in the UK.

3. Terminology
3.1 Definitions—For definitions of terms used in this test method refer to Terminology C43C1232, and Specifications C1167 and
C1492.
4. 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.
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 instructi
