ASTM C170/C170M: Compressive Strength of Dimension Stone

← Back to all standards

ASTM C170 is the test method for the compressive strength of dimension stone, covering sampling, specimen preparation, and testing. To match this to your program, talk with our team.

What ASTM C170 Covers

It determines how much compressive load natural dimension stone can carry, used to qualify stone for building and cladding applications.

How the Test Is Run

Prepared stone specimens with flat, parallel faces are loaded in compression to failure at a controlled rate, and the compressive strength is calculated from the maximum load and area, in a dry or wet condition as required.

Why It Matters

Compressive strength is a core acceptance property for building stone; accurate high-force loading and flat bearing surfaces are essential.
