D5168-22 – Standard Test Method Technical Guide
ASTM D5168-22 provides a standardized practice for the fabrication and closure of new triple-wall corrugated fiberboard containers. This practice is crucial for ensuring the structural integrity and performance of shipping containers in various industries. The standard is under the jurisdiction of ASTM Committee D10 on Packaging and has been approved for use by agencies of the U.S. Department of Defense, emphasizing its reliability for demanding applications.
📐 Scope and Significance
The scope of D5168-22 explicitly covers the fabrication and closure of new triple-wall corrugated fiberboard containers. It outlines the factors and components that must be controlled during manufacture to guarantee quality. The standard uses inch-pound units as standard, with SI conversions provided for reference only. This practice does not address all safety concerns, and users are responsible for establishing appropriate safety practices.
⚠️ Important: This standard applies only to new containers, not reused or reconditioned ones. Ensure materials are fresh and undamaged for optimal performance.
⚙️ Fabrication and Closure Practices
Fabrication according to D5168-22 requires careful selection of corrugated fiberboard that meets specifications such as D4727/D4727M. Closure methods may involve adhesive sealing, strapping as per D3950 or D3953, or tape as specified in D5330/D5330M or D5486/D5486M. The practice ensures that containers can withstand transport stresses. Performance testing can be guided by D4169 for shipping containers.
The following table summarizes key test methods used to evaluate container materials.
| 🟦 Test Method | 📏 Description | 🎯 Application |
|---|---|---|
| TAPPI T 411 | Thickness of Paper and Paperboard | Ensures consistent material thickness |
| TAPPI T 803 | Puncture and Stiffness Test of Container Board | Measures puncture resistance |
| TAPPI T 810 | Bursting Strength of Corrugated and Solid Fiberboard | Determines burst strength for container durability |
| TAPPI T 811 | Edgewise Compression Strength of Corrugated Fiberboard | Evaluates stacking strength |
💡 Always verify that the fiberboard used meets the minimal performance criteria specified in the referenced standards to ensure container compliance.
