ASTM D2050-23 PDF

Overview

ASTM D2050-23: Standard Terminology Relating to Fastener Subassemblies Used in the Manufacture of Textiles is an international standard developed by ASTM International. This terminology standard provides an authoritative framework for terminology associated with fastener subassemblies commonly used in textile manufacturing. Fastener subassemblies covered by ASTM D2050-23 include components such as buttons, snap fasteners, hook and loop fasteners, and slide fasteners. These parts are integral to the construction, functionality, and durability of various textile products.

By standardizing vocabulary within textile manufacturing, ASTM D2050-23 ensures improved communication and quality control among manufacturers, suppliers, designers, and testing laboratories worldwide. It also assists in establishing requirements for textile fasteners and their related testing, supporting compliance with both industry and international practices.

Key Topics

ASTM D2050-23 covers terminology related to the following major fastener subassembly types used in textile manufacturing:

• Buttons: Defines terms for different button types, manufacturing processes (e.g., injection molding, compression molding), features (e.g., shank, flange, holes), and properties like launderability and drycleanability.
• Hook and Loop Fasteners: Offers definitions describing components, mechanics (hooks and loops interface), and performance metrics such as shear strength.
• Snap Fasteners: Clarifies terms for various snap designs, including prong-ring types, components (socket, stud), and functional characteristics like holding strength and snap action.
• Slide Fasteners (Zippers): Explains the components of zippers, including sliders, stringers, elements, and types (continuous or individual element fasteners), as well as terms related to their assembly and performance.
• Joining Methods: References key methods for joining textile sections, such as stitches and seams.

Each section provides specific, standardized definitions to prevent misinterpretation, facilitating precise communication and documentation within the global textile industry.

Applications

ASTM D2050-23 is applicable across a wide spectrum of textile-related activities:

• Textile Manufacturing: Provides manufacturers with standardized terms for fastener subassemblies and connection methods used in garments, upholstery, and other fabric-based products.
• Quality Control and Testing: Enables consistent identification and specification of fastener parts during product testing, inspection, and certification processes.
• Product Design and Development: Assists designers and engineers in selecting appropriate fastener components for specific textile applications, improving product performance and user experience.
• Procurement and Supply Chain Management: Eases procurement processes by ensuring that specification documents, purchase orders, and contracts use consistent, universally understood terminology for textile fasteners.
• International Trade and Compliance: Supports adherence to international trade agreements and regulatory frameworks by adopting language that aligns with globally recognized standards.
