The Standard Helmet Visual Field Tester is a precision instrument designed to evaluate the peripheral vision and visor obstruction of safety helmets. It provides accurate angular measurements for upper, lower, and lateral fields of view, ensuring compliance with international helmet safety standards. This tester supports ergonomic and repeatable testing of various helmet types, including cycling, industrial, and sports helmets.
Application
The tester is suitable for a wide range of helmet evaluation scenarios, including:
(1) Testing peripheral vision of adult cycling helmets (road and mountain bikes)
(2) Assessing visor obstruction in skateboarding and roller skating helmets
(3) Verification of industrial safety helmets used in construction and manufacturing
(4) Quality control for helmet manufacturers during production
(5) Research and development of new helmet designs with customized visor geometries
Standards
The equipment complies with international and regional safety standards:
(1) EN 1078:2023 – Helmets for Pedal Cyclists, Skateboarders, and Roller Skaters
(2) ASTM F1446 – Standard Test Method for Helmets (equivalent compliance)
(3) CE Certification (Conformité Européenne)
(4) ISO 17025 – General requirements for the competence of testing and calibration laboratories
Features
(1)High-Precision Angular Measurement: Motorized goniometer with 0.01° resolution for accurate field-of-view assessment.
(2)Comprehensive Rotational Testing: 360° rotational stage evaluates visor obstruction from all angles.
(3)Adaptive Leveling: Auto-leveling system compensates for helmet tilt during testing.
(4)User-Friendly Operation: 7” touchscreen HMI with preloaded EN 1078 sequences and pass/fail indicators.
(5)Quick-Swap Modular Head: Rapid replacement of headforms for adult, child, or custom helmets (50–65 cm circumference).
(6)Data Integrity: Built-in data logger exports results in PDF/CSV formats, SD card storage for long-term archives.
(7)Durable Construction: Aircraft-grade aluminum frame and anti-scratch visor protection withstand 5,000+ test cycles.
(8)Self-Calibrating System: Auto-tare and angular alignment checks ensure measurement reliability.
Corrosion-Resistant Frame: 304 stainless steel with epoxy coating for laboratory durability.
