(Test Method)Standard Test Method for Pullout Resistance of Ties and Anchors Embedded in Masonry Mortar Joints
Standard Test Method for Pullout Resistance of Ties and Anchors Embedded in Masonry Mortar Joints
SIGNIFICANCE AND USE
5.1 This test method is intended to provide a simple inexpensive means of generating conservative, comparative data on pullout strengths of various ties and anchors used with different types of masonry units and mortars. This test method is recommended for such use until economical, improved methods can be developed to simulate service conditions more inclusively.
SCOPE
1.1 This test method provides procedures for determining the ability of individual masonry ties and anchors to resist extraction from a masonry mortar joint.
1.2 Two laboratory testing procedures are provided for use with test specimens which consist of a masonry tie or anchor embedded in mortar between twin stack-bonded masonry units.
1.2.1 Procedure A—For use with small (brick-size) masonry units.
1.2.2 Procedure B—For use with large (block-size) masonry units.
1.3 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.
1.4 This standard does not purport to address 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.

INTRODUCTION
The attachment of masonry walls to building exteriors has been based largely on experience and
professional judgment. Codes and standards requirements relating to the attachment of masonry
veneer and nonload-bearing masonry walls generally specify the size and spacing of the fasteners to
be provided (ties or anchors) rather than the forces to be resisted. In addition, there are very limited
data available on the structural performance of most types of fasteners currently used in masonry
construction.
This test method is recommended for determining conservative ultimate pullout values of masonry
fasteners under conditions that approach those usually found in the upper courses of masonry wall
construction, which experience little or practically no vertical load restraint. Its use is recommended
until more comprehensive methods are developed which can evaluate, economically, the capacity of
masonry ties and anchors to resist pullout loads, giving due consideration to service parameters such
as expanse of surrounding wall area and in-plane dead loads.
