A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Load is applied, separately, perpendicular to the surface of the panel and parallel to the surface of the panel. This test is intended to represent the interaction of the anchor with the stone panel.
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.

Current edition approved Oct. Summary of Test Method 4. The mechanical anchor is connected to a test support. A test load is applied perpendicular or parallel to the face of the stone panel.
The test load is applied gradually using a calibrated test machine; load is increased until the stone or the mechanical anchor fails. The test as described above is repeated? The strength of a limited length of anchor may be related to a longer length of support when the? Refer to Guide C Support Frame and Loading Device 7. In addition, the support frame shall be sufficiently stiff to limit de?
The anchor shall be attached to the support frame in the asym way it will be attached to the backup structure in construction. The sample of stone is supported at the opposite end by a 25 mm 1 in.
ASTM C – 96 Standard Test Method for Strength of Individual Stone Anchorages in Dimension Stone
The sample of stone panel is held down while the upward load is applied through a single sample of anchor. The stone sample may be held down by independent anchors as shown in Fig. The area beneath the anchor shall be 2 kept unsupported to prevent restraint of spalls that may arti? The surface between the loading plate and the stone panel sample shall be lubricated.
If sealant, epoxy, or other form of kerf? Alternatively, provisions may be made to distribute the load from the anchor to the stone with a soft bearing material. Stone samples shall be taken from slabs oriented asstm to rift as will be used in construction. Stone suppliers shall provide the following information: If it is desired to measure fracture strength of stone when it exceeds the strength of the metal anchor, an additional set of tests shall 4 More specimens may be needed depending on the variability of the test results.
If necessary, determine suitable statistical parameters to evaluate the composite variability and to select the number of specimens needed for obtaining a given minimum precision in determining the capacity of the anchorage system.
Test specimens immediately upon removing from the bath, wiping the specimen free of surface water. Observe and record the failure of the load applied to each specimen.
If restraint devices have interfered with the fracture plane, note it and adjust the locations of the restraint devices. The designer specifying the test shall state what de?
