A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. Scope 1. Only those tests required by the specifying authority need to be performed. 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.

The structural member is not prohibited from being steel-reinforced. The location and orientation of any reinforcement embedded in concrete or masonry members shall be evaluated. This procedure shall also be repeated for each variation in the structural member. Position the loading device in such a way that it is centered over the anchor to be tested. Provide uniform contact between the surface of the structural member and the support system. In the nal alignment of the support system, ensure that the forces to be applied through the loading rod are perpendicular to the surface of the structural member section.

The amount of torque or pretension applied to the anchor by the attaching nut or locking device shall be uniform for each series of tests. Whenever a loading plate is required in the testing of a cluster of anchors, ensure uniform loading of the individual anchors of the cluster.

A reaction bridge is not required along the edge of the structural member if the edge distance is larger than 4 hef in all directions.

Place the loading plate-rod assembly onto the structural member and secure it in place with the appropriate nut or other locking device typically used for the particular anchor installation to be tested.

The amount of force exerted on the loading plate by the attaching nut or locking device shall be uniform for each series of tests performed.

For tests that require precise anchor load-displacement data for calculating stiffness or assessing proper functioning, the continuous load application method is required. Plot the initial and 2-min readings of the measurement devices in the form of load-displacement curves. Maintain complete load-displacement records throughout the test or plot after completion of the test. The data records shall include a time record of the beginning and end of each increment of constant load.

The corrected displacement at maximum or at any other test load is observed from the plot relative to the adjusted zero-load displacement value.

Seismic Tests 9. E 96 9. The steel weight is then set over the hole or the installed anchor. This weight is secured to the structural member by the anchor see Fig.

Inspect the anchor for failure or any suspected damage after each set of cycles. Fatigue Tests The conguration of the test systems shall be such that no resonant vibrations are produced during the tests. If the objective is to obtain runout at or below the endurance limit that is, 2 3 cycles at a given load, then three samples that reach runout are sufficient.

If the test objective is to determine the maximum load that will reach runout the endurance limit , then tests in accordance with Practice E shall be performed.

Shock Test Three separate anchor tests at a given load without failure shall be sufficient to establish the maximum shock capacity of the anchorage system. After application of the shock loads, the anchors shall be tensile tested in accordance with the Static Tests section to measure residual static tensile capacity, if required.

Failure Criteria Displacement failure is evidenced by continuous displacement associated with a constant or decreasing applied load. Some anchorage systems require deformation to become effective. This provision does not apply to that deformation. Report The moisture content of the structural member at time of test is determined by several methods, including drying of small samples to constant weight or use of moisture meters; Precision and Bias The testing device shall be of sufficient capacity to prevent yielding of its various components and shall ensure that the applied tension loads remain parallel to the axes of the anchors and that the applied shear loads remain parallel to the surface of the structural member during testing.

Calibrated load cells which meet the specied rate of loading given herein shall be used. For eld tests which require displacement measurements, use either manually read dial gages or electronic load and displacement measuring devices, provided they are capable of generating a minimum of 50 data points prior to reaching peak load.

For eld tests requiring displacement measurements, the instrument s shall be positioned to measure the vertical movement of the anchor with respect to points on the structural member in such a way that the instrument is not inuenced during the test by deection or failure of the anchor or structural member.

The test system support shall be of sufficient size to prevent failure of the surrounding structural member. The loading rod shall be of such size to develop the ultimate strength of the anchorage hardware with minimal elastic elongation and shall be attached to the anchorage system by means of a connector that will minimize the direct transfer of bending stress through the connection.

The components of the test xture shall be of sufficient size and strength to prevent their yielding during ultimate capacity tests on the anchorage system. The initial shape of the hole in the loading plate shall correspond to that of the anchor cross section and shall be FIG. Worn or deformed holes shall be repaired. Insert sleeves of the required diameter shall be periodically installed in the loading plate to meet these requirements.

The edges of the shear loading xture shall be chamfered or have a radius to prevent digging in of the loading plate. Dial gages having an accuracy of FIG. The anchors shall be tested at distances equal to or greater than those given in Table 2.

The distances in Table 2 are not intended for design of attachments. Table 2 test support requirements are not prohibited from being reduced for bonded anchors with embedments equal to or greater than 20 anchor diameters. For anchors intended to be? The structural member is not prohibited from being steel-reinforced. Where steel failures occur, only a minimum of three anchors per size shall be tested and the three test results averaged.

This procedure shall also be repeated for each variation in the structural member. Position the loading device in such a way that it is centered over the anchor to be tested. Provide uniform contact between the surface of the structural member and the support system.

In the? The amount of torque or pretension applied to the anchor by the attaching nut or locking device shall be uniform for each series of tests.
