Testing & Certification
This section covers testing procedures, certification standards, and quality assurance for pallets.
Standard Testing Procedures
Load Capacity Testing
Pallets are tested for their ability to handle various loads:
| Test Type | Description | Standard |
|---|---|---|
| Static Load Test | Tests pallet's ability to handle a stationary load over time | ISO 8611-1 |
| Dynamic Load Test | Tests pallet's performance during lifting and moving | ISO 8611-2 |
| Racking Load Test | Tests pallet's ability to support loads when placed on racking systems | ISO 8611-3 |
| Impact Test | Tests pallet's resistance to impacts and drops | ASTM D6179 |
Material Testing
Tests to ensure material quality and consistency:
- Moisture Content Testing: Ensures wood has appropriate moisture levels
- Fastener Hold Testing: Measures the strength of nail, screw, or staple connections
- Durability Testing: Repeated use cycles to test longevity
- Temperature Resistance: Performance under extreme temperatures
Certification Standards
International Standards
- ISO 8611: International standard for pallet testing
- ISPM-15: International phytosanitary standard for wood packaging
- UIC Code 435-2: European railway pallet standard
- ASTM D6199: American standard for performance testing
Regional Certification Programs
- EPAL Certification: European Pallet Association certification
- PDS (Pallet Design System): North American pallet design certification

Quality Assurance Processes
Manufacturing QA
Steps during pallet manufacturing to ensure quality:
- Material Inspection: Pre-production checks on lumber, fasteners, etc.
- In-Process Verification: Dimensional checks during assembly
- Post-Production Testing: Sample testing of completed pallets
- Batch Certification: Documentation and tracking of production batches
Repair and Recertification
Processes for ensuring reconditioned pallets meet standards:
- Visual Inspection Criteria: Guidelines for identifying damaged components
- Repair Standards: Requirements for acceptable repairs
- Component Replacement Specifications: Standards for replacement parts
- Post-Repair Testing: Verification of repaired pallet integrity
Testing Equipment
Standard equipment used in pallet testing:
- Compression Testers: Measuring maximum load capacity
- Impact Testing Apparatus: Simulating drop and handling impacts
- Vibration Tables: Replicating transportation conditions
- Moisture Meters: Measuring wood moisture content
Self-Assessment Guide
