Safety Helmets Wearing Stability Tester
The Safety Helmets Wearing Stability Tester is designed to evaluate helmet retention and fit under dynamic conditions, simulating real-world head movements and impact scenarios. It provides precise measurement of helmet stability, retention forces, and deformation, ensuring compliance with international and national safety standards. The instrument is suitable for production quality control, R&D, and certification testing of industrial, sports, and cycling helmets.
Application
This tester is suitable for assessing helmet fit stability and retention performance for:
(1) Industrial helmets used in construction, manufacturing, and mining
(2) Cycling helmets for road, mountain, and urban riding
(3) Sports helmets for skating, climbing, skiing, and other high-mobility activities
(4) Motorcycle and E-bike helmets for rider safety certification
(5) R&D of custom helmet designs with adjustable retention systems
Standards
The tester complies with the following standards:
(1) GB 811-2022 – Safety Helmets: General Technical Requirements
(2) GB 24429-2009 – Sports Helmets: Requirements and Test Methods
(3) GB/T 2812 – Safety Helmets: Test Methods
(4) ISO 6220-2 – Industrial Safety Helmets: Fit Stability
(5) CE Certification (Conformité Européenne)
Features
Multi-Standard Compliance: Simulates extreme lateral forces and evaluates retention system integrity.
High-Precision Measurement: 0.1kg load resolution and 0.1N force sensor accuracy for repeatable results.
Dynamic Tilt Testing: 360° tilt mechanism reproduces real-world head movements.
User-Friendly Operation: 7” touchscreen HMI with preloaded GB/T 2812 sequences and real-time force graphs.
Quick-Swap Helmet Clamp: Rapid replacement of helmets for high-throughput labs.
Safety Systems: Dual interlocks and overload protection prevent accidental activation and sensor damage.
Self-Calibrating System: Auto-tare and linearity checks before each test.
Durable Construction: Aircraft-grade aluminum frame and corrosion-resistant sensors ensure long-term reliability.

Test Procedures
Secure the helmet in the universal clamp and adjust to the correct head circumference.
Select the wearing stability test mode via the touchscreen HMI.
Set impact weight and initial load according to test requirements.
Adjust tilt angle and initiate the motorized tilt stage.
Monitor real-time force graphs and retention performance during rotation.
Export data as PDF or CSV for certification or R&D analysis.
Repeat tests for additional helmets as required.
Maintenance Information
Inspect helmet clamps, tilt mechanism, and load cells regularly; replace worn parts.
Verify calibration of force sensors every six months using NIST-traceable instruments.
Clean frame, clamps, and sensors with non-corrosive solutions to maintain accuracy.
Store the tester in a dry, temperature-controlled environment to prevent corrosion.
Follow standard electrical safety procedures during operation and maintenance.
