Full title and description
ASTM D1506-23 — Standard Test Methods for Carbon Black—Ash Content. Methods for determining the non‑carbon (ash) residue remaining after ignition of carbon black samples; includes requirements for sample preparation, controlled combustion/ignition, residue recovery and calculation of ash content, and reporting in SI units.
Abstract
ASTM D1506-23 specifies standardized laboratory procedures to determine the ash content of carbon black materials by controlled combustion and gravimetric determination of residue, providing repeatable results for quality control, specification and regulatory reporting.

Scope
This standard covers test methods for the determination of ash content in carbon black. It defines sample handling and preparation, controlled ignition/combustion procedures, residue recovery and weighing, calculation of percent ash, and reporting conventions (values stated in SI units). The standard notes safety considerations and references the responsibility of the user to apply appropriate laboratory safety and environmental controls.
Key topics and requirements
- Definition of ash content and its significance for carbon black quality and performance.
- Requirements for sample collection, representative sampling and sample preparation.
- Specified ignition/combustion procedure(s) and apparatus considerations for complete combustion and minimal contamination of residue.
- Gravimetric recovery and weighing of residue, with calculation method for ash percentage (mass of residue divided by original sample mass × 100).
- Precision and repeatability expectations, and requirements for reporting results and test conditions.
- Safety, health and environmental considerations for high‑temperature combustion and handling of residues.
- Requirement to report results in SI units and to follow the standard’s reporting format and identification (D1506-23).
Typical use and users
Used by carbon black manufacturers, rubber and polymer compounders, quality control and analytical laboratories, material specification engineers, and R&D groups. Typical applications include incoming raw material inspection, process control, specification compliance, and comparative characterization of carbon black grades for rubber compounding and other industrial uses.
Related standards
Other test methods published by the ASTM D24 committee and related D‑series standards for carbon black characterization (surface area/iodine adsorption, structure, particle size), plus relevant ISO test methods for carbon black and general analytical procedures for gravimetric determinations and combustion analysis. Users often apply D1506 in concert with other carbon black test methods for comprehensive material characterization.
