ASTM C1354/C1354M-22

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: C1354/C1354M − 21 C1354/C1354M − 22
Standard Test Method for
Strength of Individual Stone Anchorages in Dimension
Stone
This standard is issued under the fixed designation C1354/C1354M; the number immediately following the designation indicates the
year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last
reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method provides procedures for determining the ultimate strength of an assembly consisting of stone with mechanical
anchor (anchorage). 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. However, influence of the backup structure on
the strength of the assemblies is not included.
1.2 This test method is applicable to stone panels supported by mechanical anchors.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the
two systems may result in non-conformance with the standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.1.2 anchorage, n—assembly consisting of a stone panel with a mechanical anchor.
3.1.3 panel, n—cut stone with large face dimensions in relation to its thickness, for placement in a building structure or frame
assembly.
4. Summary of Test Method
4.1 Test specimens consisting of a stone panel sample and a mechanical anchor are fabricated in the same manner and of the same
materials as their intended construction uses. 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.
4.2 The load at failure and mode of failure of each test specimen is observed and recorded. The test as described above is repeated
five times for each combination of stone and anchor to be tested and for each direction of load to be tested.
5. Significance and Use
5.1 This test method is intended to provide information from which applicable design data can be determined for a given anchor
used to support a dimension stone panel. 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. Refer to Guide C1242.
6. Testing Machine
6.1 The testing machine shall conform to the requirements of Practices E4.
6.2 The load from the testing machine shall be applied through appropriate devices (a lubricated ball-and-socket or a lubricated
universal joint) to apply direct tension to the test specimen without bending.
7. Support Frame and Loading Device
7.1 The support frame (excluding the anchor to be tested) shall have sufficient strength to not yield while supporting maximum
applied load. In addition, the support frame shall be sufficiently stiff to limit deflection to less than 0.04 in. [1 mm] at maximum
test load and to limit rotation to less than 2°.
7.2 For load perpendicular to the surface of the stone panel:
7.2.1 A rubber pad or a setting gypsum bed shall be used between the stone and the loading or restraint surface to avoid
concentration of stress in the surface of the stone sample.
7.2.2 A frame to support a stone sample with anchor in the side edge of the stone is shown in Fig. 1. Fig. 1 represents outward
loading on a single stone panel. At the designer’s option, two stone panels can be tested on a single split anchor.
7.2.2.1 The test specimen is supported at one end by the anchor. The anchor shall be attached to the support frame in the same
way it will be attached to the backup structure in construction. The sample of stone is supported at the opposite end by a 1 in. [25
mm] diameter rod.
7.2.2.2 The load from the testing machine is applied to the stone sample through a 1 in. [25 mm] diameter rod, located as close
as possible to the anchor that supports the stone but at a distance not less than the thickness of the panel.
7.2.3 A frame to test a stone sample with anchor in back of the stone and the load applied in a direction perpendicular to the panel
are shown in Figs. 2 and 3. 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. 2 or by the device used to apply load as
shown in Fig. 3.
7.3 For load parallel to the surface of the stone panel:

7.3.1 The stone panel sample is restrained in the plane of the panel while a test load is applied parallel to the plane of the panel
as shown in Fig. 4. The area beneath the anchor shall be kept unsupported to prevent restraint of spalls that may artificially increase
the strength. The surface between the loading plate and the stone panel sample shall be lubricated.
8. Test Specimens
8.1 Anchorage System—The anchorage system shall be representative of the type to be used in field construction and shall include
the anchor to be used and all accessories normally required to attach the anchor to the backup structure. If sealant, epoxy, or other
form of kerf filler is specified to be used in field construction, the bond between the sealant, epoxy, or other form of kerf filler shall
be intentionally prevented in the test assembly. Alternatively, provisions may be made to distribute the load from the anchor to the
stone with a soft
