Subscription pricing is determined by: Already Subscribed to this document. The structural member will act as a beam if the spacing between reaction supports is greater than the thickness of the member. As the voice of the Asttm. Position the loading device in such a way that it is centered over s488 anchor to be tested.
Product-specific evaluation and acceptance standards may add specific details and appropriate parameters as needed to accomplish the testing. Plot the initial and 2-min readings of the sstm devices in the form of load-displacement curves. The structural member is not prohibited from being steel-reinforced.
E 96 FIG. A superscript epsilon e indicates an editorial change since the last revision or reapproval. If the document is revised or amended, you will be notified by email. Environmental exposures include freezing and thawing, astn, decreased and elevated temperatures and corrosion. A minimum of data points per instrument shall be obtained and recorded for each individual test. For anchors intended to be? 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.
Testing shall begin only after the test specimens have reached at least an appropriate stable condition with regard to temperature and moisture content. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Precision and Bias Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The data records shall include a time record of the beginning and asym of each e48 of constant load.

However, anchor diameters, threads, and related testing equipment shall be in accordance with either inch-pound or SI provisions. This standard is also available to be included in Standards Subscriptions.
We have no amendments or corrections for this standard. Nothing in this standard, however, shall preclude combined tests incorporating two or more of these types of loading such as seismic, fatigue and shock tests in series.
For tension tests, displacement is measured along the axis of the anchor, and for shear tests, displacement is measured perpendicular to the axis of the anchor, in mm in. Worn or deformed holes shall be repaired. Cast-in-place concrete, grout-set, and epoxy-set anchors are some examples of anchorage systems that require provisions for aging or curing.
The Effect of Steel Co A minimum of data points per instrument shall be obtained and recorded for each individual test. The load and displacement measuring devices shall be capable of providing data points at least once per second in order to produce continuous load versus displacement curves.

Active view current version of standard. Astm A – A The overall size of the test specimen shall not be reduced unless the requirements in 6. 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.
Tested in accordance with ACI Please first verify your email before subscribing to alerts. Current edition approved May 10, The materials used include epoxy, cementitious material, polyester resin, and other similar types. Only those tests required by the specifying authority need to be performed. E4488 4 Practices for Force Veri? An extension of the axis of the shear loading rod or plate shall pass through the centric axis of the cluster of anchors.
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. 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 corrected displacement at maximum or at any other test load is observed from the plot relative to the adjusted zero-load displacement value.
This standard has been approved for use by agencies of the Department of Atm. The materials used include epoxy, cementitious material, polyester resin, and other similar types. You may delete a document from your Alert Profile at any time.
Only those tests required by the specifying authority need to be performed. The choice of the controlled conditions shall sstm the conditions under which the anchors will be used. Historical Version s – view previous versions of standard. E — 96 concrete or masonry members shall be evaluated.
The enlarged diameter section of the hole is predrilled or enlarged by an expansion process during setting of the anchor. E 96 3.
