IEC 62471 / EN 62471 Photobiological Safety Testing

IEC 62471 / EN 62471 Photobiological Safety Testing & Risk Assessment

CTNT Zhongwei Inspection provides comprehensive optical radiation hazard assessments for lamps and lamp systems in accordance with the international benchmarks IEC 62471 / EN 62471 / GB/T 20145. We scientifically quantify product risk levels (Exempt Group, Risk Group 1 – low risk, Risk Group 2 – moderate risk, Risk Group 3 – high risk), delivering key safety evidence for global market access. This standard applies to all non‑laser optical radiation sources, including LED luminaires and modules, various displays (mobile phones, computers, televisions), projectors, stage lights, ultraviolet disinfection lamps, beauty lamps, and intense pulsed light (IPL) devices. Equipped with professional systems such as imaging luminance meters and spectroradiometers, we accurately assess core hazards including retinal blue light hazard, ultraviolet hazard, retinal thermal hazard, infrared radiation hazard, and skin thermal hazard. We not only provide test data but also offer in‑depth interpretation of risk levels, analysis of hazard sources, and product optimisation recommendations. This testing is a mandatory requirement for multiple markets, including EU CE certification (EN 62471), North America (ANSI/IES RP‑27), and China (GB/T 20145). Backed by authoritative accreditations including CMA, CNAS, and IAS, our reports are widely recognised globally, helping you meet multi‑country photobiological safety compliance requirements in one go, avoiding legal disputes and consumer complaints caused by blue light, ultraviolet, and other hazards at the source, and providing solid scientific endorsement for your product safety.



IEC 62471 / EN 62471 Photobiological Safety Testing

IEC 62471 / EN 62471 Photobiological Safety Testing & Risk Assessment

Comprehensive Optical Radiation Hazard Assessment for Lamps and Lamp Systems Based on the International Benchmarks IEC 62471 / EN 62471 / GB/T 20145 – Scientifically Quantify Your Product‘s Risk Level and Provide Key Safety Evidence for Global Market Access


I. Everything You Need to Know About IEC 62471 / EN 62471

1. Standard Full Name & Introduction

  • Full Name: IEC 62471 “Photobiological safety of lamps and lamp systems”

  • Issuing Body: International Electrotechnical Commission (IEC)

  • Core Purpose: This standard is the global scientific benchmark for assessing the potential health hazards (primarily to the eyes and skin) of all non‑laser optical radiation sources – i.e., lamps and lamp systems. Through measurement and calculation, it classifies products into four risk groups: Exempt Group, Risk Group 1 (low risk), Risk Group 2 (moderate risk), and Risk Group 3 (high risk).

2. Why Is This Standard So Important?

  • (1) Scientifically Quantify Risks
    Go beyond subjective perception – use precise irradiance and radiance data to quantify the optical radiation hazards of your product in the blue light, ultraviolet, and infrared bands, providing scientific evidence for product safety.

  • (2) Foundation for Global Market Access
    It is the most basic and mandatory safety requirement for lamps and lamp systems in many countries and regions, including EU CE certification (EN 62471) and North America (ANSI/IES RP‑27 series).

  • (3) Mitigate Legal Liability
    Eliminate consumer complaints, legal disputes, and large claims caused by blue light retinal hazard, ultraviolet skin hazard, and other risks from light source products at the source.


II. Our IEC 62471 / EN 62471 Testing Service Scope

1. Applicable Product Range

Almost all powered non‑laser light source products, especially:

  • LED luminaires, bulbs, and modules (e.g., classroom lights, desk lamps, industrial lighting)

  • Various displays (mobile phones, tablets, computers, televisions)

  • Projectors, stage lights, ultraviolet disinfection lamps

  • Beauty lamps, intense pulsed light (IPL) beauty devices

  • Various special light sources (e.g., infrared lamps, medical lighting equipment)

2. Core Testing Items & Hazard Assessment

  • Retinal blue light hazard: Assess the photochemical damage risk of short‑wave blue light to the retina.

  • Ultraviolet hazard: Assess the hazard of UV radiation to the cornea, lens, and skin (e.g., UV keratitis, skin erythema).

  • Retinal thermal hazard: Assess the retinal temperature rise damage caused by near‑infrared radiation.

  • Infrared radiation hazard to the eye: Assess the potential effect of infrared radiation on the lens.

  • Skin thermal hazard: Assess the burn risk of infrared radiation to the skin.

3. Related Markets & Directives

  • Directly relevant to: EU CE certification (Low Voltage Directive/LVD), China Compulsory Certification (CCC – for certain product categories), and safety market access in major global markets.

  • Derived standards: EN 62471 (EU), GB/T 20145 (China).


III. Why Choose Us for IEC 62471 / EN 62471 Testing?

  1. Equipped with professional‑grade measurement systems such as imaging luminance meters and spectroradiometers, ensuring accurate and reliable data for complex light sources (e.g., non‑uniform displays).

  2. We not only provide test data but also offer risk level interpretation, hazard source analysis, and product optimisation recommendations – helping you improve product safety design at the source.

  3. With deep understanding of global derived standards such as IEC 62471, EN 62471, and GB/T 20145, we help you meet the optical safety compliance requirements of multiple markets in one go.

  4. Directly endorsed by national CMA, CNAS, and IAS accreditations – our reports are widely recognised by market regulatory authorities at all levels.

IV. Accreditations & Frequently Asked Questions

1. Accreditations
Our testing services are performed strictly within the scope of CNAS accreditation. Our IEC 62471 / EN 62471 test reports are widely recognised by customers.

2. Frequently Asked Questions

Q: What is the difference between IEC 62471 and the laser safety standard IEC 60825‑1?
A: IEC 62471 applies to non‑laser broadband light sources (e.g., LED lights, displays) and assesses their overall radiation hazards. IEC 60825‑1 applies to lasers – monochromatic, highly directional light sources. The product types and physical characteristics covered by the two standards are completely different. If a product contains both a laser and ordinary light sources, it may need to comply with both standards.
