1. Dimensional Inspection
The first step is verifying the "unloaded" physical specs using high-precision calipers or optical measuring systems
2. Torque and Deflection Testing
Since torsion springs provide rotational force, a specialized Torque Tester is required.
3. Material and Surface Quality
The durability of a spring depends on its "skin" and internal structure.
4. Load Life & Fatigue Testing
For safety-critical parts (like garage door springs or automotive components), manufacturers perform "cycle testing."
