(Test Method)Standard Test Methods for Testing Bond Performance of Bonded Anchors
Standard Test Methods for Testing Bond Performance of Bonded Anchors
SIGNIFICANCE AND USE
4.1 These test methods are intended to provide information from which applicable design data and specifications are derived for a given anchorage device and for qualifying anchors or anchorage devices.
4.2 These test methods shall be followed to ensure reproducibility of the test data.
SCOPE
1.1 These test methods cover instructions for making a variety of tests for the strength of the adhesive bond developed between a steel anchor and the surface of a hole in concrete or masonry (including masonry units and mortar joints) and for assessing the effects on such bond of a variety of factors including elevated temperature, fire, moisture, and freezing and thawing action. The specifier or manufacturer shall select those tests that are appropriate for the given anchoring system and intended application.
1.2 The adhesive-bonded anchor system refers to a smooth or deformed steel bar or threaded rod, set in a predrilled hole containing chemical bonding compounds. Loads are transferred mainly by the bond of the adhesive both to the anchor and the surrounding elements along the sides of the hole. For anchoring systems made of significantly different materials, these test methods shall be taken as a guideline.
1.3 These test methods apply to all adhesives used to bond steel anchors or steel reinforcement bars (rebar) to concrete or masonry. These test methods apply to anchorages used in uncracked concrete or masonry. They do not apply to the use of the anchor in the concrete tension zone. The usual forces applied during the tests are in tension, shear, and under a combination of both tension and shear.
1.4 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.
1.5 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 to determine the applicability of regulatory limitations prior to use.

1. Scope
1.1 These test methods cover instructions for making a variety of tests for the strength of the adhesive bond developed between
a steel anchor and the surface of a hole in concrete or masonry (including masonry units and mortar joints) and for assessing the
effects on such bond of a variety of factors including elevated temperature, fire, moisture, and freezing and thawing action. The
specifier or manufacturer shall select those tests that are appropriate for the given anchoring system and intended application.
1.2 The adhesive-bonded anchor system refers to a smooth or deformed steel bar or threaded rod, set in a predrilled hole
containing chemical bonding compounds. Loads are transferred mainly by the bond of the adhesive both to the anchor and the
surrounding elements along the sides of the hole. For anchoring systems made of significantly different materials, these test
methods shall be taken as a guideline.
1.3 This standard applies These test methods apply to all adhesives used to bond steel anchors or steel reinforcement bars (rebar)
to concrete or masonry. These test methods apply to anchorages used in uncracked concrete or masonry. They do not apply to the
use of the anchor in the concrete tension zone. The usual forces applied during the tests are in tension, shear, and under a
combination of both tension and shear.
1.4 The values stated in inch-pound units are to be regarded as the standard. The SI units values given in parentheses are for
information only.mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 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 to determine the applicability of regulatory
limitations prior to use.
These test methods are under the jurisdiction of ASTM Committee E06 on Performance of Buildings and are the direct responsibility of Subcommittee E06.13 on

(76 mm) 3-in. (76-mm) radius from the center of the test anchor, with tap water, maintaining a minimum of ⁄2-inch (12 mm) -in.
(12-mm) depth throughout the test. Load each anchor with a constant tension load equal to at least 40 % of the ultimate load
capacity of the baseline tests for restrained tests, or 40 % of the ultimate load capacity for the same size anchor determined in
Section 7.2 for an unrestrained test. This load is to be maintained during the freezing and thawing cycles. The nominal freezing
and thawing cycles shall consist of alternately lowering the temperature of the chamber to −10°F (−23°C) and holding this
temperature for 3 hours,h, then raising the temperature to 104°F (40°C) and holding this temperature for 3 hours.h. Measure the
temperature at the surface of the concrete at a location outside the standing water. At the completion of fifty complete cycles,
conduct tension tests and compare the results to the baseline test results or to the results determined in Section 7.2 for the same
size anchor as applicable.
7.4.6 Tests on Effects of Damp Environment—The tests shall be conducted as restrained tests, or unrestrained tests. If testing is
conducted in the restrained mode, baseline tests are required. Install and test a minimum of three anchors. Prior to anchor
installations, fill the test holes with tap water and maintain the water level filled for a minimum of seven days. Immediately prior
to installing the anchors, all freestanding water shall be removed so that the walls of the test holes are surface moist. After the
appropriate cure time has elapsed, conduct tension tests to failure and compare the results to the baseline test results or to the results
determined in Section 7.2 for the same size anchor as applicable. If the application requires installation in water-filled holes,
conduct the test as described above except that the freestanding water is not removed. Install the anchors in the water-filled holes.
