The stone sample may be held down by independent anchors as shown in Fig.

However, influence of the backup structure on the strength of the assemblies is not included. If sealant, epoxy, or other form of kerf? Support Frame and Loading Device 7. Alternatively, provisions may be made to distribute the load from the anchor to the stone with a soft bearing c154. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Link to Active This link will always route to the current Active version of the standard.
The surface between the loading plate and the stone panel sample shall be lubricated.
Historical Version s – view previous versions of standard. Combining values from the two systems may result in non-conformance with the standard.
The anchor shall be attached to the support frame in the same way it will be attached to the backup structure in construction.
The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. 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.
The strength of a limited length of anchor may be related to a longer length of support when the flexibility of the support is properly considered by the designer. c1345
A precision section will be added when sufficient data are available to indicate acceptable tolerances in repeatability and reproducibility. This standard is subject to revision at any time by the responsible technical committee and astk be reviewed every?
Asfm area beneath the anchor shall be 2 kept unsupported to prevent restraint of spalls that may arti? Stone suppliers shall provide the following information: The designer specifying the test shall state what de?
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The sample of stone is supported at the opposite end by a 25 mm 1 in. Summary of Test Method 4. Refer to Guide C Actual dimensions of each sample tested rather than astmm dimensions shall be measured and reported, 4 asstm The test load is applied gradually using a calibrated test machine; load is increased until the stone or the mechanical anchor fails.
Load is applied, separately, perpendicular to the surface of the panel and parallel to the surface of the panel. Refer to Guide C The mechanical anchor is connected to a test support. 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.
The strength of a limited length of anchor aastm be related to a longer length of support when the?

Precision and Bias It is the responsibility of the user of this standard to establish appropriate safety and health c13544 and determine the applicability of regulatory limitations prior to use. 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.
If restraint devices have interfered with the fracture plane, note it and adjust the locations of the restraint devices. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. A test load is applied perpendicular or parallel to the face of the stone panel.

It is the responsibility of the user ashm this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Current edition approved Oct.
In addition, the support frame shall be sufficiently stiff to limit de? This test is intended to represent the interaction of the anchor with the stone panel. The sample of stone panel astk held down while the upward load is applied through a single sample of anchor.
Stone samples shall be taken from slabs oriented relative to rift as will be asfm in construction. Load is applied, separately, perpendicular to the surface of the panel and parallel to the surface of the panel.
A number in parentheses indicates the year of last reapproval. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. The test as described above is repeated?
