However, anchor diameters, threads, and related testing equipment shall be in accordance with either inch-pound or SI provisions. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Only those tests required by the specifying authority need to be performed.
A number in parentheses indicates the year of last reapproval.
Environmental astn include freezing and thawing, moisture, decreased and elevated temperatures and corrosion. 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 e488 the anchorage system by means of a connector that will minimize the direct transfer of bending stress through the connection. E 96 Reapproved Standard Test Methods forStrength of Anchors in Concrete and Masonry Elements1This standard is issued under the d488 designation E ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
Link to Active This link will always route to the current Active version of the standard. Insert sleeves of the required diameter shall be periodically installed in the loading plate to meet these requirements.
The displacement to be used for the evaluation of the? The amount of torque or pretension applied to the anchor by the attaching e88 or locking device shall be uniform for each series of tests.
The information provided herein on the specimens, instrumentation, and procedures makes the results intractable to calculation of meaningful values by statistical analysis for precision and bias at this time. It is the responsibility of the user of this aztm to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Calibrated electronic load and displacement measuring devices which meet the sampling rate of loading specied herein shall be used. Astm E – E These test methods provide basic testing procedures for use with product-specific evaluation and acceptance standards and are intended to be performed in a testing laboratory.
Link to Active This link will always route to the current Active version of the standard. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. 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.
A number in parentheses indicates the year d488 last reapproval. Worn or deformed holes shall be repaired. The components of the test? The test system support shall be of sufficient size to prevent failure of the surrounding structural member. For tests on clusters of anchors, the instrument shall lie on a plane through the axis of the shear loading rod or plate. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
The enlarged diameter section of the hole is predrilled or enlarged by an expansion process during setting of the anchor. E — 96 awtm load, when calibrated in accordance with Practices E 4.
Need more e4888 one copy? The testing may be performed in either system and reported in that system and the results converted to the other. Work Item s – proposed revisions of this standard.
Published on Nov View 1. A minimum of data points per instrument shall be obtained and recorded for each individual test. 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.
The choice of the controlled conditions shall simulate the conditions under which the anchors will be used. The materials used include epoxy, cementitious material, polyester resin, and other similar types. Include components of deformation such as elastic elongation of the loading rod anchor stem, deformation of the loading plate, sleeves, shims, attachment hardware, and local structural member material. The test system support shall be of sufficient size to prevent failure of the surrounding structural member.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Standards Subsctiption may be the perfect solution.
Some anchorage systems require deformation to become effective. Deduct all of the elongations from these sources from the total displacement measurements by using supplementary measuring devices or calibration test data for the installed test set-up with rigid specimen replacing the anchor to be tested.
The overall size of the test specimen shall e4888 be reduced when the minimum requirements in 6. The materials used include epoxy, cementitious material, polyester resin, and other similar types. The initial shape of the hole in the loading plate shall correspond to that of the anchor cross section and shall beFIG. The readings shall be obtained prior to reaching peak load.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Calibrated load cells which meet the specied rate of loading given herein shall be used. Dial gages having an accuracy of FIG. Position the loading device in such a way that it is centered over the anchor ee488 be tested.
The corrected displacement at maximum or at any other test load is observed from the plot relative to the adjusted zero-load displacement value.
