EN 136 Mask Visual Field Testing Machine VF-7000: Precision Vision Compliance Testing for Respirator
Overview
The VF-7000 is an advanced automated system designed to evaluate the visual field of filtering facepiece respirators (FFPs) in compliance with EN 136:2023 standards. Critical for manufacturers of occupational PPE, this instrument ensures that respirators provide adequate peripheral vision without obstructing the wearer’s field of view, a key requirement for safety in high-risk environments.
Core Features
Dynamic Visual Field Simulation:
- Simulates human head movements and pupil positioning to test horizontal and vertical visual fields (≥120° horizontally, ≥80° vertically) as mandated by EN 136.
- Adjustable chin/forehead rests and interchangeable headforms (S/M/L sizes) for universal mask compatibility.
High-Precision Optical Sensors:
- Equipped with high-resolution cameras and infrared sensors to track eye movements and detect visual obstructions with ±0.5° accuracy.
- Real-time display of field-of-view heatmaps and coverage metrics.
Automated Testing Protocols:
- Preloaded EN 136 test sequences for FFP1, FFP2, and FFP3 respirators, including static and dynamic (movement-induced) visual assessments.
- Customizable test parameters (e.g., light conditions, target contrast).
Integrated Environmental Simulation:
- Adjustable temperature (5–40°C) and humidity (20–90% RH) to replicate workplace conditions during testing.
Compliance Automation:
- Generates automated reports with EN 136 pass/fail indicators, including field-of-view diagrams and obstruction analysis.
Technological Innovations
- AI-Powered Obstruction Detection: Machine learning algorithms differentiate between mask design limitations and test artifacts, reducing false positives by 95%.
- 3D Headform Calibration: Laser-scanned headforms ensure precise alignment with human anatomical standards.
- Modular Design: Swapable fixtures for testing full-face respirators, half-masks, and powered air-purifying respirators (PAPRs).
Applications
- Respirator Manufacturing: Certify FFP respirators for visual field compliance during EU market certification (CE marking).
- Occupational Safety Testing: Validate designs for firefighters, miners, and industrial workers requiring unobstructed vision.
- R&D Labs: Develop next-gen masks with optimized lens materials and ergonomic designs.
- Regulatory Bodies: Conduct impartial testing for EN 136 certification audits.
