Overview
ASTM D6799-23, Standard Terminology Relating to Inflatable Restraints, provides comprehensive definitions for terms used in the evaluation and manufacturing of inflatable restraint fabrics, cushions, and modules. As an international standard developed by ASTM International, it helps unify language and concepts across industries involved in producing automotive safety systems such as airbags. The terminology ensures precise communication during research, design, testing, and quality assurance, reducing ambiguity in technical documentation and standardizing evaluation criteria for this critical safety component.
Key Topics
The standard covers terminology relevant to:
- Inflatable restraint systems: Definitions for airbags, cushions, inflators, modules, and related components.
- Fabric characteristics and evaluation:
- Terms describing textile features (e.g., woven patterns, coated fabrics, and imperfections).
- Defects, imperfections, and common fabric faults relevant to safety and performance.
- Testing and quality control:
- Procedures and definitions for tests such as accelerated aging, dynamic air permeability, grading, and inspection.
- Terms for environmental and laboratory testing atmospheres.
- Assembly and manufacturing:
- Seam types, failures (adhesive and cohesive), and definitions of sealed and sewn seams.
- Techniques such as rework, packability, and specific packability.
Key terminology enables clear communication among engineers, manufacturers, and quality control professionals, supporting the safe and effective production of inflatable restraint systems.
Applications
ASTM D6799-23 brings practical value in several key areas:
- Automotive Safety System Development: Provides standardized language for manufacturers, suppliers, and testing laboratories involved in airbag design, prototyping, and production.
- Quality Assurance and Inspection: Enables consistent description and assessment of fabric quality and defect types, supporting reliability and safety standards for airbag modules.
- Product Testing and Evaluation: Supports methodical evaluation of materials and assemblies for performance under various environmental conditions (heat, humidity, ozone) and at different deployment pressures.
- International Trade and Regulation: Aligns terminology across borders, aiding compliance with World Trade Organization (WTO) Technical Barriers to Trade (TBT) principles and facilitating smoother regulatory approval processes globally.
