3.1 Definitions, acronyms, and units given in Section 4 of this terminology are intended for use in all standards for declarable substances in materials. The definitions shall be used uniformly and consistently.

If the technical subcommittee responsible for the standard feels that it is appropriate, the term and its definition may appear in both the standard and in this terminology.
3.4 The Subcommittee shall consult the ASTM Dictionary of Engineering Science & Technology or a standard dictionary, or both, prior to creating a new definition to determine if a suitable definition already exists. Other terminology documents, such as ISO 472 Plastics—Vocabulary, may also be consulted.
