ASTM C880 is the test method for the flexural strength of dimension stone using a simple beam with quarter-point loading. To match this to your program, talk with our team.
What ASTM C880 Covers
It determines the flexural strength (modulus of rupture) of natural dimension stone, used to qualify stone panels and cladding that must resist bending.
How the Test Is Run
A stone beam is supported near its ends and loaded at the quarter points until it fractures, and the modulus of rupture is calculated from the peak load and beam dimensions.
Why It Matters
Flexural strength governs stone cladding and panel design; a stiff frame with quarter-point fixturing and a controlled rate is required.
