ASTM C1799/C1799M-22e1 PDF

Overview

ASTM C1799/C1799M-22e1: Standard Guide to Dimension Stone Test Specimen Sampling and Preparation sets forth basic recommendations for the sampling, selection, preparation, and conditioning of dimension stone specimens to be used in testing material properties. Developed by ASTM, this international standard serves as a key reference for professionals involved in the design, selection, specification, installation, or testing of natural stone in construction applications. It ensures test results are relevant, reproducible, and directly related to real-world performance needs.

Dimension stones are inherently variable materials due to their natural origin. As such, proper specimen sampling and preparation are critical for obtaining reliable test data. Such data are foundational in building rational designs and verifying if a stone's properties meet the intended use.

Key Topics

• Purpose of Testing: Testing dimension stone quantifies material properties such as flexural strength, compressive strength, absorption, and density. These data points aid designers and engineers in predicting performance across specific applications.
• Sampling Recommendations: The standard discusses methods for selecting samples that represent the average grade and quality supplied to the market. It also addresses the complications posed by stone anisotropy and rift orientation.
• Preparation of Specimens: Guidelines specify how test specimens should be sawn, finished, and marked to ensure consistency, including details on right-angle cuts and surface finishes.
• Conditioning Protocols: Procedures for preparing specimens under dry and wet conditions are included to mimic various service environments. Conditioning typically involves fixed drying and immersion periods.
• Reporting Requirements: Clear instructions are provided for documenting specimen source, preconditioning, test procedures, and results, supporting transparency and traceability.

Applications

ASTM C1799/C1799M-22e1 provides significant practical value across the dimension stone industry:

• Architects and Engineers: Use the guide to specify stone testing requirements and interpret test data when designing assemblies requiring natural stone.
• Contractors and Fabricators: Reference the standard for sampling and sample preparation to ensure that material supplied aligns with project specifications.
• Material Suppliers: Rely on these guidelines to prepare compliant test specimens, supporting sales, quality assurance, and compliance documentation.
• Testing Agencies: Apply standardized specimen preparation and conditioning methods, ensuring test validity and reproducibility.

The standard is also essential for projects where stone properties must be verified according to both SI and inch-pound units, providing international applicability.
