ASTM D907-15(2023) PDF

Overview

ASTM D907-15(2023): Standard Terminology of Adhesives is a foundational standard developed by ASTM International that compiles and standardizes definitions commonly used in the adhesives industry. This document serves as a central reference for terminology in the science and technology of adhesives, ensuring clarity and consistency across research, manufacturing, and application sectors worldwide. By focusing exclusively on terms specific to adhesives that are not readily defined elsewhere, ASTM D907 enhances communication and understanding for professionals in the field.

The standard supports international best practices and aligns with principles established by the World Trade Organization’s Technical Barriers to Trade (TBT) Committee, making it an essential document for global manufacturers, suppliers, and regulatory bodies working with adhesives.

Key Topics

ASTM D907-15(2023) covers a broad range of terminology essential to the adhesives industry, including but not limited to:

• General Adhesive Terms: Definitions of adhesives, adhesion, and adherends, plus distinctions between types such as anaerobic, hot-melt, pressure-sensitive, and structural adhesives.
• Adhesive Application and Performance: Clarification of concepts like assembly time, bond strength, wet strength, dry strength, peel strength, and shear strength.
• Failure Modes: Specification of various failure types, including adhesion failure, cohesion failure, and substrate failure, with descriptions of their occurrence in bonded joints.
• Materials and Composition: Terminology for materials such as binders, fillers, extenders, resins, and plasticizers commonly found in adhesive formulations.
• Test Methods and Procedures: Key definitions for acceptance tests, qualification tests, and preproduction tests, as well as reference to related ASTM test standards.
• Bonding and Joint Types: Detailed language about joint types (edge joint, lap joint, laminate joint), preparation methods, and assembly processes.

Special attention is given to the documentation of changes in terminology since 1988, with a comprehensive historical record maintained in Appendix X1, which tracks additions, revisions, and deletions.

Applications

The terminology outlined in ASTM D907-15(2023) ensures precise communication among:

• Manufacturers and Suppliers: Facilitates accurate product descriptions, safety data, and instructions, minimizing errors and misunderstandings in specifications and procurement.
• Quality Control and Testing Laboratories: Supports consistent reporting and interpretation of adhesive test results, including strength, durability, and failure analysis.
• Product Designers and Engineers: Enables precise articulation of adhesive requirements for a variety of applications, including wood products, composites, automotive, aerospace, electronics, packaging, and construction.
• Regulatory Agencies: Aids in the creation of standards, certifications, and compliance documents by providing unambiguous terminology shared across the adhesives industry.
• Research and Development: Assists scientists and researchers in the development of new adhesives and bonding technologies by ensuring that innovations are described in universally understood terms.
