ASTM D7158/D7158M-24a

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: D7158/D7158M − 24 D7158/D7158M − 24a
Standard Test Method for
Wind Resistance of Asphalt Shingles (Uplift Force/Uplift
1
Resistance Method)
This standard is issued under the fixed designation D7158/D7158M; 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 the procedure for calculating the wind resistance of asphalt shingles when applied in accordance with
the manufacturer’s instructions and sealed under defined conditions. Shingle designs that depend on interlocking or product rigidity
to resist the wind cannot be evaluated using this test method. The method calculates the uplift force exerted on the shingle by the
action of wind at specified conditions, and compares that to the mechanical uplift resistance of the shingle. A shingle is determined
to be wind resistant at a specified basic wind speed for standard conditions (see 6.3) when the measured uplift resistance exceeds
the calculated uplift force for that velocity (3 s gust, ASCE 7).
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the
two systems may result in nonconformance with the 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, health, and environmental practices and determine the applicability of
regulatory limitations prior to use.
1.4 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.
