ASTM ACTIVATED CARBON STANDARDS
Summary: If you are a manufacturer, distributor, buyer or user of activated carbon media or products, you have undoubtedly seen the various terms and test methods used to specify activated carbon and seen the name ASTM and a test number listed as a standard reference such as Iodine number 900 minimum per ASTM D 4607. ASTM activated carbon standards are an important tool that allows manufacturers to have quality control test standards for production purposes and permits end-users to compare activated carbon products using such properties such as hardness, ash, activity, density, moisture, etc. that might have implications for their application or use of the activated carbon. This article reviews ASTM and specifically how the Committee on Activated Carbon, D-28, is structured and how activated carbon standards are developed.
ASTM International (American Society for Testing and Materials) was organized in 1898 and is a not-for-profit organization that provides a forum for the development and publication of standards for materials, products, systems, and services.
