Full title and description

ASTM D4790-25 — Standard Terminology of Aromatic Hydrocarbons and Related Chemicals. This document provides standardized definitions and terminology used for aromatic hydrocarbons and closely related chemical classes to ensure consistent communication across testing, specifications, regulatory documents, and commercial literature. DOI: 10.1520/D4790-25; developed by ASTM Committee D16, Subcommittee D16.05.

Abstract

This short ASTM terminology standard lists and defines terms commonly used in the characterization, specification, and handling of aromatic hydrocarbons and related chemicals (for example, common names, structural descriptions, and solvent classifications). It is intended to harmonize vocabulary used by laboratories, manufacturers, regulators, and standards writers.

Scope

The scope of ASTM D4790-25 is limited to defining terminology — it does not prescribe test methods, performance criteria, or handling procedures. It covers names, descriptive phrases, and classification terms for aromatic hydrocarbons and closely related substances that appear in ASTM test methods, product specifications, regulatory texts, and technical literature. The standard is intended for use where a concise, agreed vocabulary reduces ambiguity in specifications and reports.

Key topics and requirements

• Standardized definitions for common aromatic hydrocarbon names and classes (e.g., benzene derivates, substituted aromatics).
• Classification terms used for solvents and aromatic-containing streams.
• Preferred nomenclature and cross-references to commonly used synonyms.
• Guidance on usage of terms in specifications and test-method references.
• Short document structure suitable for incorporation by reference into other ASTM methods.

Typical use and users

ASTM D4790-25 is used by standards writers, laboratory managers, chemists, technical writers, specification authors, regulatory personnel, and purchasers who need consistent terminology for aromatic hydrocarbons across reports, labels, and test methods. It is typically referenced within other ASTM test methods and specifications to ensure consistent language.

Related standards

This terminology standard supersedes the previous edition D4790-23 and is cited by multiple ASTM test methods and specifications that reference aromatic-hydrocarbon terminology. Examples of standards that reference or are associated with D4790 include several D-series methods for solvents and coatings; consult the ASTM index or national catalogues for a current list of referencing documents.
