Safety Helmet Lateral Rigidity Tester
The Safety Helmet Lateral Rigidity Tester is a precision instrument designed to evaluate the lateral deformation resistance of helmets under controlled loading. It measures force-displacement behavior with high accuracy, ensuring compliance with national and international helmet safety standards. The tester accommodates various helmet sizes and types, providing repeatable and reliable testing for both production quality control and R&D applications.
Application
This tester is suitable for evaluating lateral rigidity in various helmet testing scenarios, including:
(1) Industrial safety helmets used in construction, manufacturing, and mining
(2) Cycling helmets for road and mountain biking
(3) Sports helmets for skating, skiing, and snowboarding
(4) Motorcycle and E-bike helmets for rider safety certification
(5) Quality control and R&D of helmet designs with different shell materials or thicknesses
Standards
The tester complies with the following standards:
(1) GB 2812 – Safety Helmets (China National Standard)
(2) ISO 6220-2 – Industrial Safety Helmets: Lateral Deformation
(3) CE Certification (Conformité Européenne)
(4) ISO 17025 – General requirements for testing and calibration laboratories
Features
High-Precision Lateral Testing: 0–1,000N load capacity with 0.1mm displacement resolution.
Accurate Force Control: ±1% force accuracy and adjustable test rate of 100N/min.
User-Friendly Operation: 7” touchscreen HMI with preloaded GB 2812 test sequences and auto-hold functions.
Quick-Swap Helmet Clamp: Enables rapid replacement of helmets for high-throughput testing.
Data Integrity: Built-in data logger exports force-displacement curves in PDF/CSV formats for audit trails.
Durable Construction: Aircraft-grade aluminum frame and stainless steel sensors resist deformation and corrosion.
Dynamic Force Feedback: Real-time monitoring of peak loads via 0.1N resolution load cell.
Self-Calibrating System: Auto-tare and linearity checks ensure measurement reliability.
Rust-Resistant Frame: 304 stainless steel with epoxy coating for laboratory durability.

Test Procedures
Secure the helmet in the universal clamp and select the appropriate size configuration.
Set the desired test rate and maximum displacement via the touchscreen HMI.
Activate the motorized compression stage to apply lateral force.
Monitor real-time force-displacement curves on the LED display.
Export and save results in PDF or CSV format for audit and analysis.
Repeat testing for additional helmets as required.
Maintenance Information
Clean the helmet clamps and compression stage regularly to remove dust and debris.
Inspect and replace drive belts and bearings periodically to maintain smooth operation.
Verify load cell calibration every 6 months using NIST-traceable instruments.
Store the instrument in a dry environment to prevent corrosion of aluminum and steel components.
Follow standard electrical safety protocols during operation and maintenance.
