ASTM D7144

ASTM D7144 is a technical standard that describes a practice for collecting surface dust by micro-vacuum sampling for later determination of metals and metalloids. It is designed to support consistent sample collection when surface dust needs to be analyzed for elemental content. By providing a defined approach to dust recovery, the standard helps improve comparability, quality control, and confidence in downstream laboratory results for environmental and material assessment work.

What is ASTM D7144?

ASTM D7144, Standard Practice for Collection of Surface Dust by Micro-vacuum Sampling for Subsequent Determination of Metals and Metalloids, sets out a practical sampling approach for capturing dust from surfaces using micro-vacuum methods. Its focus is on the collection step, not the analytical measurement itself. This makes it useful where a controlled, repeatable dust sample is needed before metals and metalloids are determined by a separate test method or laboratory procedure.

Where is ASTM D7144 used?

This practice is commonly used in workflows that involve surface dust sampling followed by elemental analysis. It may be applied in environmental investigation, materials assessment, or quality-related testing where dust must be collected carefully from a surface without unnecessary disturbance. ASTM D7144 is relevant whenever technicians need a consistent micro-vacuum collection method to support subsequent laboratory determination of metals and metalloids from the recovered dust sample.

Why is ASTM D7144 important?

ASTM D7144 matters because the quality of a dust analysis often depends on how the sample is collected. A clear collection practice helps reduce variability, supports more reliable results, and improves consistency across operators and projects. For organizations that rely on surface dust data for compliance, screening, or technical evaluation, using a recognized standard can strengthen confidence in sampling results and help support defensible decision-making.
