Full title and description
ASTM C880/C880M-25 — Standard Test Method for Flexural Strength of Dimension Stone. Defines the procedure for determining flexural strength of dimension stone using a simple beam with quarter-point loading, including provisions for testing orientation relative to bedding planes and for wet conditions.
Abstract
This test method specifies a laboratory procedure to measure the flexural (bending) strength of dimension stone by loading a simple beam at quarter points. Results provide a comparative measure of flexural performance for material selection, quality control, and specification verification. The method treats SI and inch–pound units as independent standards and includes guidance for testing specimens parallel and perpendicular to bedding planes and, where required, under wet conditions.

Scope
This standard covers the procedure for determining the flexural strength of stone by use of a simple beam using quarter-point loading. It applies to tests with the load applied both perpendicular and parallel to the bedding plane and provides for testing under wet conditions when required. SI and inch–pound units are provided and must be used independently (values in one system are not exact equivalents of the other). The method does not by itself address all safety concerns associated with testing.
Key topics and requirements
- Test configuration: simple beam subjected to quarter-point loading to determine flexural strength (modulus of rupture style measurement).
- Specimen orientation: testing provisions for loads applied perpendicular and parallel to bedding planes to reflect anisotropy in stone.
- Conditioning: procedures include testing under wet conditions when required by the user or specification.
- Units: separate SI and inch–pound procedures/values — do not mix unit systems for compliance.
- Intended use: comparative evaluation of stone flexural performance for selection, QC, and specification verification; the standard notes users must observe appropriate safety practices.

Typical use and users
Used by materials testing laboratories, quarry and stone producers, specification authors, architects, structural and façade engineers, stone fabricators, quality assurance personnel, and researchers evaluating dimension stone performance for building and architectural applications.
Related standards
Commonly referenced and complementary ASTM standards for dimension stone testing include: ASTM C97 (absorption and bulk specific gravity), ASTM C99 (modulus of rupture / related flexure tests), ASTM C170/C170M (compressive strength), ASTM C241 (abrasion resistance), and standards for stone cladding performance such as ASTM C1201. These standards are produced by the same ASTM technical committees for dimension stone and are often specified together for comprehensive material characterization.
