I presume that you mean C568-99 Standard Specification for Limestone Dimension Stone. You might also want to look at: 1. C1242-96b Standard Guide for Design, Selection, and Installation of Exterior Dimension Stone Anchors and Anchoring Systems 2. C170-90 Standard Test Method for Compressive Strength of Dimension Stone Harold Sprague The Neenan Company -----Original Message----- From: Tarek Mokhtar [mailto:Tarek(--nospam--at)deltanet.com] Sent: Saturday, October 16, 1999 12:18 PM To: seaint(--nospam--at)seaint.org Subject: Stone Attachment Q I am reviewing Limestone attachment(mechanical) details for a building in the Los Angeles area.The stone modulus of rupture tests came in at 300PSI. ASTM 568 for Limestone building stone suggests a minimum of 400 PSI for the MOR. The UBC does not address the bending strength nor the MOR of the stone, and the latest masonry code ACI530.1-99 specifically precludes stone veneer from the chapter covering veneers. The question would be for the relevance of the ASTM standard, If the stone and its attachments are designed with adequate safety factors Opinions requested, TIA Tarek Mokhtar, SE Laguna Beach,CA.
