Photobiological risk evaluation EN62471

Photobiological risk assessment (EN62471 and IEC TR 62778) is one of the mandatory provisions imposed by the European Commission to ensure the safety of products and people.

Indeed, manufacturers and marketers of products incorporating LED-type light sources must comply with the applicable standards: EN62471 and IEC TR 62778.

Its obligations are part of the CE marking, particularly in the context of compliance with the European Low Voltage Directive (LVD).

The COFRAC accreditation of the PISÉO laboratory guarantees customers quality and impartial measurement results.

Accredited for measurements according to EN62471 and IEC TR 62778

The protocol implemented by PISEO complies with the EN 62471 standard. This allows the classification of the product studied according to 4 risk groups ranging from 0 to 3 for lighting devices but also LED optical systems.

The term “photobiological hazard” refers to the potential of LED light to injure the eye, particularly at the extreme ends of the visible spectrum.

On the blue end of the visible spectrum, the risks are with UV light, while on the red side it will be more with infrared light.

Several criteria are taken into account for the measurement result and in particular those concerning the risks for the skin and the eyes: exposure of the skin, exposure of the surface of the eye (cornea, conjunctiva and lenses), as well as the exposure of the retina in the posterior part of the eye.

Équipements de mesure pour évaluer le risque photobiologique

EVERFINE OST-300 radiometric bench

The measurements are carried out on a radiometric measurement bench entirely dedicated to photobiological risk assessment.

This bench can perform all the measurements required by the EN62471 and IEC TR62778 standards for ultraviolet, visible and infrared radiation.

PISEO has chosen to work only with state-of-the-art equipment whose manufacturers enjoy worldwide renown.

Our measuring equipment is frequently calibrated, checked and calibrated. In addition, they are implemented by qualified operators in a controlled environment (temperature, humidity, etc.). All of these parameters together ensure correct and reliable test results.

As part of the accreditation, the bench is calibrated using standard light sources connected to the International System.
