ASTM C1182 is the standard test method for determining the particle size distribution of alumina by centrifugal photosedimentation. It provides a structured way to evaluate how alumina particles are distributed across size ranges, which is important for material characterization and quality control. By using a defined testing approach, this ASTM standard helps support consistent results, better product comparison, and more reliable technical decisions in applications where particle size can influence performance.

What is ASTM C1182?

ASTM C1182 describes a test method used to determine the particle size distribution of alumina using centrifugal photosedimentation. The standard is focused on measurement rather than product specification, making it useful for laboratories and technical teams that need repeatable data on alumina powders. Because particle size distribution can affect processing behavior and end-use performance, this ASTM standard is a practical reference for controlled testing and documented evaluation of alumina materials.

Where is ASTM C1182 used?

ASTM C1182 is commonly used in laboratory and quality assurance settings where alumina powder must be characterized with care. It is relevant in material development, incoming inspection, and comparative testing workflows that rely on particle size data. The method may also be used when specifying alumina for production or research purposes, especially when consistent powder properties are important. In these settings, ASTM C1182 supports measurement discipline and helps align test results across teams and facilities.

Why is ASTM C1182 important?

This standard matters because particle size distribution can strongly influence how alumina behaves in processing and use. ASTM C1182 gives buyers, suppliers, and laboratories a shared test method that supports consistency and reduces uncertainty in reported results. Using a recognized ASTM standard can improve confidence in material evaluation, help with procurement decisions, and support quality control programs. It also makes it easier to compare alumina data from different sources using the same technical basis.
