Radio Frequency Testing

TUV certification provides internationally recognized proof of safety compliance for monitors and display devices. This guide covers the TUV certification pathway for monitors, including applicable standards, key testing requirements, and practical strategies for efficient certification.

TUV Certification Overview for Monitors

TUV (Technischer Überwachungsverein) certification is a voluntary third-party safety certification widely recognized in European and global markets. For monitor manufacturers, TUV certification serves several purposes:

• Demonstrates compliance with European safety standards beyond the basic CE marking self-declaration

• Required by many European distributors and institutional buyers as a procurement condition

• TUV mark provides enhanced market credibility compared to self-declared CE compliance

Two main TUV organizations operate independently: TUV Rheinland and TUV SUD. Both issue internationally recognized certificates, but they maintain separate certification processes and marks.

Applicable Standards

Monitor TUV certification primarily addresses safety and ergonomic requirements:

EN 62368-1　Audio/video, information and communication technology equipment — Safety requirements

EN 60950-1　Legacy standard (still accepted for some existing product lines under transition provisions)

EN ISO 9241-307　Ergonomics of human-system interaction — Analysis and compliance test methods for electronic visual displays

CB scheme:TUV certificates can be based on IEC 62368-1 CB testing for international recognition

For monitors with ergonomic claims (eye comfort, flicker-free, low blue light), TUV Rheinland offers specialized certification programs that go beyond basic safety.

Key Safety Testing Requirements

Monitor safety testing under EN 62368-1 includes these critical evaluations:

• Energy source classification:Monitor internal power supply primary side classified as ES3 (hazardous energy), requiring reinforced insulation from accessible parts

• Insulation and clearance:Primary-secondary reinforced insulation, creepage and clearance distances per EN 62368-1 tables

• Temperature testing:Component and enclosure temperatures under normal and abnormal operating conditions

• Mechanical stability:Monitor stand and tilt mechanism stability, VESA mount strength verification

• Fire enclosure:Plastic enclosures must meet flame retardancy requirements (5V or V-0 depending on fire hazard assessment)

TUV Eye Comfort Certification

Beyond basic safety, TUV Rheinland's Eye Comfort certification has become a significant market differentiator for monitors. The certification evaluates:

• Flicker-free operation (PWM dimming frequency above critical threshold or DC dimming)

• Low blue light emission (spectral distribution measurement and weighted blue light intensity)

• Reflection management (anti-glare coating effectiveness)

• Image quality consistency (luminance uniformity, contrast ratio)

Eye Comfort certification can be conducted alongside the safety TUV certification, saving time and sample costs. GTG Group assists monitor manufacturers with both safety and eye comfort certification programs.

Certification Timeline and Multi-Market Strategy

Monitor TUV certification typically takes 6-10 weeks, including:

• Safety testing: 4-6 weeks

• Eye Comfort testing (if applicable): adds 2-3 weeks

• Factory inspection: 2-3 weeks (initial certification)

Strategic recommendation: Apply for TUV certification through the CB scheme, obtaining a CB report that can be used for multiple market conversions (UL for US, KC for Korea, PSE for Japan). This approach maximizes the return on testing investment.
