ASTM G144

ASTM G144 is a test method for determining residual contamination in materials and components by total carbon analysis using a high temperature combustion analyzer. It is used to help identify remaining carbon-based residues that may affect cleanliness, performance, or downstream processing. For organizations that need a clear, standardized way to evaluate surface or part cleanliness, this ASTM standard supports more consistent testing and more reliable quality decisions.

What is ASTM G144?

ASTM G144, titled Standard Test Method for Determination of Residual Contamination of Materials and Components by Total Carbon Analysis Using a High Temperature Combustion Analyzer, provides a structured approach for measuring residual contamination through total carbon analysis. The standard is centered on combustion-based analysis, which may be used to assess carbon remaining on materials or components after cleaning or processing. As an ASTM standard, it helps define a common technical basis for comparison, reporting, and compliance-related testing.

Where is ASTM G144 used?

ASTM G144 is commonly used in laboratories, manufacturing quality control, and contamination verification workflows where residual carbon on materials or components must be assessed. It is relevant wherever cleaned parts, processed surfaces, or sensitive components may need confirmation of low contamination levels before further use, assembly, or evaluation. The standard is especially useful in settings that rely on high temperature combustion analyzers for consistent, repeatable testing and documented results.

Why is ASTM G144 important?

ASTM G144 matters because it gives organizations a standardized way to measure residual contamination instead of relying on informal inspection or inconsistent methods. That can improve comparability between test results, support procurement and acceptance decisions, and reduce the risk of contamination-related performance issues. For quality control and product evaluation, the standard helps create clearer testing expectations and more dependable documentation. ASTM G144 also supports more disciplined compliance and verification practices.
