Torque Test Procedure in Garments & Accessories Quality Control
A torque test is a critical quality assurance method used to measure the rotational force required to loosen or remove accessories such as metal buttons, rivets, snap fasteners, eyelets, decorative studs, belt buckles, and necklace clasps.
Why Torque Testing Matters
Torque testing ensures that accessories are securely attached and can withstand normal usage without becoming loose or detached.
- Prevents product failure
- Reduces choking hazards for children
- Meets buyer and international safety standards
- Improves durability and customer satisfaction
Common Testing Equipment
Digital Torque Tester · Manual Torque Tester · Proper Grip/Jig Fixture
Step-by-Step Torque Test Procedure
- Prepare the Sample – Select a garment/accessory and check for visible defects.
- Fix the Sample – Secure the sample firmly in the fixture.
- Attach the Grip – Use the correct jig for the accessory type.
- Apply Rotational Force – Rotate clockwise and counterclockwise at 0.5–2 rpm.
- Record Maximum Torque – Note the highest reading before loosening or breakage.
- Evaluate Results – Compare with buyer specification.
Typical Test Conditions
- Rotation Speed: 0.5–2 rpm · Direction: Clockwise & Counterclockwise · Sample Size: 3–5 pcs · Units: N·m / lbf·in / kgf·cm
Acceptance Criteria
A product passes when: No loosening or detachment occurs · No cracks, deformation, or thread damage appear · Appearance remains acceptable after testing.
Example: Required Spec = 0.80 N·m ; Measured = 0.92 N·m → PASS ; Measured = 0.60 N·m → FAIL.
Common Failure Types
Loose accessories · Part detachment · Cracks or breakage · Surface damage · Thread stripping
Relevant Standards
ASTM International ASTM F963 · U.S. CPSC · ISO 8124 · Buyer-specific requirements (Walmart, Target, H&M).
Tips for Accurate Testing
- Use the correct grip for each accessory
- Ensure proper alignment and clamping
- Calibrate the tester regularly
- Take multiple readings for consistency
Key Takeaway: Torque testing is not just a lab requirement—it is a vital safety and quality control process that ensures every accessory remains secure, durable, and compliant with global standards.
