ASTM D6477-23 PDF

Overview

ASTM D6477-23: Standard Terminology Relating to Tire Cord, Bead Wire, Hose Reinforcing Wire, and Fabrics is an internationally recognized standard issued by ASTM International. This standard provides a comprehensive dictionary of terminology specific to the tire cord fabric industry, including definitions for tire cords, bead wires, hose reinforcing wires, and related fabrics. Developed under the jurisdiction of ASTM Committee D13 on Textiles, particularly Subcommittee D13.19 on Tire Cords and Fabrics, ASTM D6477-23 is essential for ensuring clear and consistent communication across the global tire reinforcement sector.

By compiling unique and precise definitions, ASTM D6477-23 supports industry professionals, manufacturers, testing laboratories, and quality assurance teams in maintaining a consistent understanding of key terms, reducing confusion and redundancy, and facilitating international trade and product standardization.

Key Topics

ASTM D6477-23 covers a wide range of terms relevant to the production, testing, and usage of tire cords and reinforcement materials, including but not limited to:

• Tire Cord: Twisted or formed structures made from one or more filaments, strands, or yarns of organic or inorganic materials used in tire construction.
• Bead Wire and Tire Bead: Steel wire components that form and reinforce the edge of the tire, ensuring a secure fit to the wheel rim.
• Hose Reinforcing Wire: Steel filaments designed to reinforce rubber or elastomer hoses for increased pressure resistance.
• Fabrics: Definitions related to woven or non-woven materials used as reinforcements in tires.
• Adhesion, Dip, and Tack: Terms describing the processes and attributes that enhance the bond between textile cords and rubber, critical for tire integrity.
• Mechanical Properties: Including breaking force, breaking strength, elongation, and work-to-break-essential metrics for evaluating material performance.
• Thermal Properties: Such as thermal shrinkage and thermal shrinkage force, relevant to processing and long-term durability.
• Process Terms: Including vulcanization, curing, and stitching, describing manufacturing and finishing operations.
• Testing Conditions: Definitions for standard atmosphere, moisture equilibrium for testing, and abrasion resistance.

Applications

The terminology set forth by ASTM D6477-23 is widely used throughout the tire manufacturing, rubber goods, and industrial textiles industries for:

• Product Development: Ensuring designers and engineers reference terms consistently when creating new tires, hoses, or reinforcement products.
• Quality Assurance and Testing: Standardizing definitions used in laboratory testing, thus enabling reliable comparisons and compliance checking.
• Procurement and Supply Chain: Facilitating clear specifications and requirements between material suppliers, manufacturers, and end users.
• Training and Documentation: Providing an authoritative resource for technical training and operational manuals.
• International Trade: Supporting harmonization of standards and reducing technical barriers, especially in compliance with WTO principles.

By adopting ASTM D6477-23, organizations ensure uniformity in communication, reduce the risk of error or misinterpretation, and uphold high quality and safety standards in reinforced rubber products.
