ASTM C1242-22b PDF Download

ASTM C1242-22b is a standard guide that provides information on the selection, design, and installation of dimension stone attachment systems. The scope of the standard covers the different categories of anchors and anchoring systems and discusses the design principles to be considered when selecting anchors or systems that can withstand gravity loads and applied loads.

The guide outlines the basic requirements for the design of stone anchorage and provides a practical checklist of design considerations. It covers various scenarios such as anchoring stone panels directly to the building structure for support, as well as anchoring stone panels to subframes or curtainwall components after these support systems are attached to the building structure. Additionally, it includes the anchoring of stone panels to subframes or curtainwall components with stone cladding preassembled before attaching them to the building structure.

The standard also emphasizes the importance of supervision and inspection of the fabrication and installation processes. It highlights the need to adhere to applicable regulations, specific recommendations of manufacturers, and standards governing interfacing work.
