I. Material Identification: Color Coding for Instant Clarity
JB/T 8521.1-2025 explicitly stipulates that the webbing material shall be identified by the color of the label. Each material corresponds to a dedicated label color to ensure rapid on-site recognition:
Material | Label Color |
Polyamide / Nylon | Green |
Polyester | Blue |
Polypropylene | Brown |
UHMWPE | Orange |
Aramid Fiber | Dark Green |
This "one-to-one correspondence" between color and material addresses the long-standing industry pain points of "material confusion" and "incorrect selection." Particularly in complex working conditions involving mixed materials, it significantly reduces potential safety hazards caused by material misjudgment.
II. Label Structure: Zoned Marking for Complete and Traceable Information
The standard provides detailed specifications for the "Sewn-in Section A" and the "Exposed Section B" of the label, ensuring that critical information is complete and legible.
Label Section | Marked Content (Minimum Size 45mm) | Function |
Sewn-in Section A | Working Load Limit (WLL), Material, Manufacturer, Traceability Code, Standard | Retains core information internally to ensure compliance |
Exposed Section B | Material, Length, Brand/Identification, Traceability Code, Standard, WLL, Minimum Width 45mm | Displays information externally for intuitive on-site verification |
Furthermore, labels must clearly indicate the "Working Load Limit (WLL)" and the "Mode Factor (M)" (e.g., Single Leg Vertical Lift M=1, Single Leg Choked Lift M=0.8, Basket Hitch M=2). This allows users to quickly determine the sling's applicable scenarios and safe load capacity.
III. Corporate Practice: Standards-Oriented, Building a Strong Safety Defense
As a company deeply rooted in the lifting equipment industry, we have fully aligned our product labeling system with JB/T 8521.1-2025:
1.Customized Labels: Strictly adhering to the "color-material" rule to ensure every sling has a clear "identity."
2.Optimized Layout: Hierarchical marking of sewn-in and exposed sections to balance compliance with readability.
3.Enhanced Traceability: Strengthening "Traceability Code" management to achieve full-process tracking from production to application.
Moving forward, we will continue to use industry standards as our benchmark. From material selection and label design to quality control, we ensure the safety and reliability of flat webbing slings across the entire chain, helping our customers "select correctly and operate safely."
IV. Industry Significance: Iterating Standards to Drive Lifting Safety Upgrades
The release of JB/T 8521.1-2025 marks a significant step in the standardization process of the lifting and rigging industry. Through the combined norms of "Color Identification + Structured Labeling + Coefficient Marking," the standard not only elevates the level of "visual safety management" but also drives the industry's transformation from "experience-driven" to "standard-driven."
We call upon our industry peers to jointly implement these new regulations. Let us use standardization to solidify the baseline of safety and technological innovation to enhance operational efficiency, working together to advance China's lifting equipment towards being "safer, smarter, and more compliant.
