Full title and description

ASTM D2652-22 — Standard Terminology Relating to Activated Carbon. This document establishes and defines terms and nomenclature used in the manufacture, characterization, testing, and application of activated carbon products to promote uniform usage and clarity in specifications, test methods, and technical communications.

Abstract

This terminology standard provides concise, agreed definitions for terms commonly used in the activated carbon field (for example: adsorption, adsorbent, activity, breakthrough, pore structure, ash, activation, chemisorption). It is intended to be used by standards authors, test laboratories, manufacturers, end users, and regulators to ensure consistent meaning when describing materials, properties, tests, and performance of activated carbon products.

General information

• Status: Active (current edition).
• Publication date: September 1, 2022 (designation D2652-22).
• Publisher: ASTM International.
• ICS / categories: 01.040.71; 71.060.10 (chemical technology / chemical elements and terminology).
• Edition / version: D2652-22 (2022 edition).
• Number of pages: 4 pages.

Scope

This terminology covers terms particularly related to activated carbon and encompasses finished products, production and activation processes, physical and chemical properties, common test and performance descriptors, and typical application vocabulary. Definitions are intended to be used where terms apply “in activated carbon” to limit their scope to the subject matter of this standard.

Key topics and requirements

• Standardized definitions for core concepts: adsorption, adsorbent, adsorbate, adsorption zone (mass transfer zone), breakthrough, and activity.
• Terms describing material properties: pore structure (micro/meso/macropores), surface area, ash, moisture (as-is basis), and abrasion resistance.
• Process and product terminology: activation, activated carbon (product families), acid-extractable material, and channeling.
• Test- and performance-related terms: accelerated adsorption tests, breakthrough, breakpoint, coadsorption, and contact batch operation.
• Editorial guidance: how definitions should be limited in general publications (for example by appending “in activated carbon” where appropriate).

Typical use and users

Used by standards committees, materials and chemical engineers, activated carbon manufacturers, test laboratories, procurement/specification authors, environmental and water-treatment professionals, researchers, and quality managers. The terminology supports consistent reporting in test methods, product data sheets, purchase specifications, regulatory submissions, and academic publications.

Related standards

Published under the jurisdiction of ASTM Committee D28 (Activated Carbon). It is commonly used alongside ASTM test methods and specifications for activated carbon products and performance (test methods and specifications developed by Committee D28). It also complements national and international methods and specifications for adsorption testing and water/gas purification materials.
