Dimension Stone Design Manual DSDM Chapter 22 - Tolerances Locked secured document

Tolerances: the allowable limit of deviation from a specified, or designed value. In some cases, like the machining of critical machine parts, that allowable deviation may be so small that it is measured in micro-inches or microns. While the stone industry does not have tolerances requiring this level of precision, there exists critical dimensions that directly affect visual appearance and structural integrity of stone installations.

Marble Soundness Classification rev. 2018 Locked secured document

The Marble Soundness Classification System has been with us, essentially unmodified, for more than half of a century (originating with the National Association of Marble Producers who merged with the Marble Institute in 1963). Its long, established use is definitely a result of its simplicity and effectiveness, but perhaps the greatest strength of this system is that it is linked only to material working properties, and specifically excludes any relationship with the market value of the materials.

Testing Frictional Properties of Natural Stone Walking Surfaces Locked secured document

Friction is currently a topic of study of numerous committees, associations, and companies, both in the United States and elsewhere. A test method and evaluation method may evolve in the future that proves to be superior to ANSI 326.3, but currently, the ANSI 326.3 procedure provides a very practical method of friction measurement and evaluation.

R-Value for Natural Stone Locked secured document

Heat always flows from warmer to colder areas. The transfer of heat energy through a solid material is known as conduction. There are certain applications where this heat transfer, or thermal conductivity, of a natural stone becomes an important factor in design and material selection.This bulletin provides the measured values of thermal conductivity (k-value) and thermal resistance (R-value) for the most common natural stone types used in building applications of common stone types.

Why Test Flexural Strength in Parallel and Perpendicular Rift Directions? Locked secured document

We’ve been awarded a large project with a very comprehensive testing specification. Our fabricator is questioning the need for testing of flexural strength in parallel and perpendicular rift directions. They explained to us that to there is no way to produce these samples without rotating the block in the gangsaw and taking slabs from two different faces of the block. Doesn’t this seem like an extreme investment of time and money just for creating test samples?

Testing Strap and Split-Tail Strap Anchors Locked secured document

Q: We are installing a small exterior façade using stainless steel strap anchors. The specs require us to test the anchors in the stone. We argued against that requirement, since strap anchors have been used in stone for generations and surely they’ve been tested before, but we were unsuccessful in that argument. We’re now getting ready to test the anchors. The single tab anchors aren’t a problem, but we’re not sure how to test the split-tail anchors. We think the anchor should be tested while engaged in two pieces of stone, just as it is in the job, but the guys at the lab are saying that that’s too difficult to set up in the lab, so they want to test the anchor with one stone only. Wouldn’t this give us low results, since the load is not balanced?
