Introduction
Core Changes in the Standard Revision
| Revision Dimensions | 2015 Edition | 2025 Edition | Technical Significance |
|---|---|---|---|
| Terminology Structure | 3 Major Categories of Terms | 4-Level Classification System | Enhance the Systematicness of Professional Terminology |
| New Terms | 32 Items | 47 Items | Covering New Materials Such as Dipped Stretch Fabric |
| Test Methods | 9 categories of indicators | 15 categories of indicators | New key parameters such as dynamic bonding strength |
Analysis of key technical terms
1. Material classification system
The standard divides impregnated skeleton materials into 7 major categories, including cord fabric, canvas, etc. Among them:
- Impregnated stretch fabric (3.2.1.8): A new definition, referring to special fabrics with elastic elongation in the warp/weft direction
- Bio-based polyamide 56 (3.2.2.7): Reflects the development trend of environmentally friendly materials
2. Key performance indicators
| Indicator name | Definition points | Application scenarios |
|---|---|---|
| H-Extraction bond strength (3.3.1.20) | Vertical pull-out force/rubber thickness | Tire cord evaluation |
| Dynamic bond strength (3.3.1.56) | Interface strength after fatigue | Conveyor belt life assessment |
Implementation recommendations
- Conversion between old and new terms: Establish a term comparison table, focusing on the deleted basic terms such as "cord fabric"
- Testing system upgrade: For the newly added
- Quality Control Points: Strictly monitor new appearance defects such as "large rough knots" (＞2mm)
Typical Application Cases
Case 1: The application of aramid dipped cord fabric (3.2.2.4) in aircraft tires requires special attention to the following:
- Dry heat shrinkage (≤1.5%)
- Dynamic bond strength (≥8N/cm)
