(Specification)Standard Specification for Limestone Dimension Stone
Standard Specification for Limestone Dimension Stone
SCOPE
1.1 This specification covers the material characteristics, physical requirements, and sampling appropriate to the selection of limestone for general building and structural purposes. Refer to Guides C1242 and C1528 for the appropriate selection and use of limestone dimension stone.
1.2 Dimension limestone shall include stone that is sawed, cut, split, or otherwise finished or shaped and shall specifically exclude molded, cast, or otherwise artificially aggregated units of composed fragments, and also crushed and broken stone.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM C568/C568M-22: Standard Specification for Limestone Dimension Stone provides comprehensive requirements for selecting and classifying limestone intended for building and structural applications. Developed by ASTM International, this standard outlines the material characteristics, physical properties, and sampling procedures necessary to ensure limestone’s suitability, durability, and performance in construction. By following recognized international standardization principles, ASTM C568/C568M-22 supports consistent quality and global trade compliance for dimension limestone used in a range of architectural and engineering projects.
Key Topics
- Material Characteristics: Specifies soundness and durability requirements, ensuring limestone is free from spalls, cracks, open seams, or any defect that may affect its structural performance.
- Physical Requirements: Establishes minimum requirements for absorption, bulk specific gravity, density, compressive strength, modulus of rupture, and abrasion resistance.
- Low-density, medium-density, and high-density classifications based on measured density
- Testing methods referenced, including ASTM C97/C97M, C99/C99M, C170/C170M, C241/C241M, and C1353, ensure objective evaluation of essential properties
- Product Definition: Limits standardized limestone dimension stone to those that are sawn, cut, split, or otherwise finished and excludes artificially aggregated or crushed stones.
- Sampling and Selection: Describes procedures for sample preparation and selection of control samples to verify color, texture, and quality across production.
- Units of Measurement: Permits use of both SI and inch-pound units independently, ensuring clear and non-ambiguous reporting in accordance with international practices.
Applications
Limestone dimension stone certified under ASTM C568/C568M-22 is widely used in:
- Building Facades: Chosen for aesthetic appeal, durability, and weather resistance in exterior cladding
- Structural Components: Used in columns, lintels, and load-bearing elements due to strict strength and density requirements
- Interior Features: Selected for flooring, wall panels, stair treads, and decorative stonework in both commercial and residential spaces
- Landscape and Site Design: Employed in architectural hardscapes, garden walls, and paving, leveraging the standard’s focus on abrasion resistance and durability
- Historic Preservation and Restoration: Assures a reliable quality benchmark when sourcing replacement materials for restoration of heritage buildings
By adhering to ASTM C568/C568M-22, specifiers, architects, contractors, and stone suppliers can be confident in the limestone’s suitability for both visual consistency and structural performance, reducing project risk and streamlining procurement processes.
