ASTM C1242-22 PDF Download

The ASTM C1242-22 standard is titled "Standard Guide for Selection, Design, and Installation of Dimension Stone Attachment Systems". This standard provides guidelines for the selection, design, and installation of anchoring systems for dimension stone. The scope of the standard covers various categories of anchors and anchoring systems and discusses the design principles that should be considered in selecting anchors or systems that can resist both gravity loads and applied loads.

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

Additionally, the standard addresses the supervision and inspection of fabrication and installation of stone anchoring systems. It emphasizes the importance of observing all applicable regulations, specific recommendations of manufacturers, and standards governing interfacing work.
