ASTM STANDARDSUnderstanding Stone Testing
Presented by: Charles Muehlbauer, Technical DirectorNATURAL STONE INSTITUTE
Learning Objectives• Awareness of Performance Requirements of Stone
Products
• Options for Stone Testing Services when no Existing Data is Available
• Identify the Pertinent Properties of Stone and the Test Methods that Measure those Properties
• Using Materials Standards to Prevent the Use of Stone Products in Unsuitable Applications

ASTM Standard Test Methods for Dimension Stones
• C 97 Absorption & Density
• C 99 Modulus of Rupture
• C 170 Compressive Strength
• C 241 Abrasion Resistance
• C1353 Abrasion Resistance by Taber Abraser

ASTM Standard Test Methods for Dimension Stones (cont’d)
• C 880 Flexural Strength
• (Withdrawn) C 1028 Static Coefficient of Friction
• C 1201 Structural Performance of Stone Cladding
• C 1352 Flexural Modulus of Elasticity
• C 1354 Individual Stone Anchorages
8
Applicability of Test Procedures
• Not all test procedures are applicable to all installations.
• For instance, Abrasion Resistance or Coefficient of Friction do not provide influential data when designing cladding.

What are we Testing for?
• Durability• Absorption/Density• Abrasion Resistance• Petrography
• Public Safety• Static Coefficient of Friction
• Strength• Compressive Strength • Flexural Strength• Anchor Strength
