About This Item
ASTM D8526 is a test method for using transmission electron microscopy to determine the concentration of carbon nanotubes and carbon nanotube-containing particles in ambient atmospheres. It is designed to support careful analytical work where airborne nanoscale materials need to be identified and quantified with a consistent laboratory approach. By defining a structured procedure, this standard helps improve comparability of results and supports informed decisions in exposure assessment, quality control, and technical review.
Overview of ASTM D8526
The official title of ASTM D8526 indicates an analytical procedure based on transmission electron microscopy for measuring carbon nanotubes and particles that contain them in ambient air. This gives the standard a focused role in microscopy-based testing of airborne particulate matter, where both detection and concentration determination are important. As an ASTM standard, it provides a recognized technical framework that can help laboratories and organizations apply a more consistent method when evaluating samples from ambient atmospheres.
Common use cases of ASTM D8526
This standard is commonly used when airborne samples must be examined for the presence of carbon nanotubes or carbon nanotube-containing particles. It may be relevant in laboratory testing workflows, environmental monitoring programs, and exposure-related evaluations where transmission electron microscopy is the chosen analytical tool. ASTM D8526 is also useful when organizations need a documented method for comparing results across sampling events, supporting internal review, or aligning testing practices with established standards.
Benefits of using ASTM D8526
Using ASTM D8526 can help bring consistency to microscopy-based analysis of airborne carbon nanotube materials. It supports more reliable testing, clearer reporting, and better comparability between laboratories or projects. For users involved in compliance, product evaluation, or risk reduction, a defined ASTM method can improve confidence in results and help reduce ambiguity during procurement, quality control, and technical decision-making. It also provides a practical reference for standardized analytical procedures.
