📐 Scope and Structure of D5684-19

ASTM D5684-19 is a comprehensive terminology standard under the jurisdiction of Subcommittee D13.21 on Pile Floor Coverings. It consolidates all terminology developed by this subcommittee, providing a unique dictionary for the pile floor covering industry. The standard is designed to manage terminology effectively and is referenced alongside D123 for other textile terms. It was developed in accordance with international principles on standardization, ensuring global relevance. This edition was approved in July 2019 and published as D5684-19a, replacing previous versions.

⚙️ Key Defined Terms in Pile Floor Coverings

The standard defines essential terms critical to the industry. For example, attached cushion refers to a material bonded to the backing fabric of a pile yarn floor covering to enhance dimensional stability and padding, with typical materials including foam, rubber, and urethane (Source: D3936). Back coating is an adhesive compound used for locking pile yarn tufts into the primary backing, bonding secondary backing, or increasing fabric stiffness and stability (Source: D5793, D5848). Below is a summary of these core definitions.

🟦 Term 📐 Definition 📖 Source Standard
Attached Cushion Material bonded to backing fabric for stability and padding, commonly foam or rubber D3936
Back Coating Adhesive compound for locking tufts, bonding backing, or increasing fabric body D5793, D5848

📊 Referenced Standards and Their Relevance

D5684-19 incorporates a wide range of ASTM standards for evaluating pile yarn floor coverings. These include test methods for tuft bind (D1335), tuft height (D5823), pile thickness (D6859), and others. The standard serves as a guide for selecting appropriate test methods and practices, as outlined in D6719. Below is a selection of key referenced standards from the document.
