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. The sample of stone panel is held down while the upward load is applied through a single sample of anchor.

The anchor shall be attached to the support frame in the same way it will be attached to the backup structure in construction.


Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

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.

Alternatively, provisions may be made to distribute the load from the anchor to the stone with a soft bearing zstm. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. Observe and record the failure of the load applied to each specimen. If it is desired to measure fracture c13544 of stone when it exceeds the strength of the metal anchor, an additional set of tests shall 4 More astj may be needed depending on the variability of the test results.

The sample of stone is supported at the opposite end by a 25 mm 1 in. 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.

The mechanical anchor is connected to a test support. This test is intended asmt represent the interaction of the anchor with the stone panel.

Combining values from the two systems may result in non-conformance with the standard. A test load is applied astmm or parallel to the face of the stone panel.

A precision section will be added when sufficient data are available to indicate acceptable tolerances in repeatability and reproducibility. Load is applied, separately, perpendicular to the surface of the panel and parallel to the surface of the panel. 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 sealant, epoxy, or other form of kerf?
