In the lifting and rigging world, ensuring your equipment performs exactly as expected isnβt just a best practice β itβs a matter of safety, reliability, and compliance. Whether preparing for a heavy lift or certifying gear for daily use, youβll encounter two main testing methods: proof testing and break testing. While both measure strength, they serve distinct purposes and are used in different stages of a productβs lifecycle.
What Is Proof Testing?
Proof testing is a non-destructive test used to confirm that rigging gear can safely handle its rated load capacity.
β Key Facts About Proof Testing
- Load is applied at a controlled level, usually above the Working Load Limit (WLL)
- The product is not damaged or permanently deformed
- Used for quality assurance before equipment enters service
- Often required by safety organizations like OSHA and standards such as ASME B30
Proof testing is typically performed on lifting devices such as:
- Wire rope and chain slings
- Synthetic slings
- Engineered lifting devices and fabrications
- Hooks, shackles, and hardware
The goal is to confirm the gear can handle expected loads safely β without compromising its future usability.
What Is Break Testing?
Break testing is a destructive test where the product is loaded until failure to determine its ultimate breaking strength.
β οΈ Key Facts About Break Testing
- The test continues until the product actually fails or breaks
- Provides accurate data on strength limits
- Used mainly for product design validation, quality control, and vendor verification
- Results help manufacturers, engineers, and distributors understand material performance under stress
Break testing is not performed on gear intended to remain in service β itβs meant to improve safety by analyzing failure points and ensuring future products meet design standards.
When Should You Use Each Test?
| SITUATION | CHOOSE PROOF TESTING | CHOOSE BREAK TESTING |
|---|---|---|
| Certifying a product for service | β Yes | β No β destroys product |
| Inspecting new or repaired equipment | β Yes | Not appropriate |
| Product development, design, QC checks | β No | β Yes |
| Vendor or material comparison | β No | β Yes |
| Regulatory compliance and documentation | β Yes | Usually not required |
