Photobiological risk evaluation EN62471

The 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.

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, in particular in the context of compliance with the European Low Voltage Directive (LVD), another international body.

Moreover, PISEO’s ISO 17025 accreditation guarantees customers quality results and impartial measurements.

Accredited for measurements according to EN62471 and IEC TR 62778

The protocol implemented by PISEO complies therefore with standard EN 62471.

This allows the classification of the studied product according to 4 risk groups ranging from 0 to 3 for lighting devices but also optical LED systems.

The term “photobiological hazard” refers in particular to the potential of LED light to harm the eye, and more specifically at the ends of the visible spectrum.

At the blue end of the visible spectrum, the risks relate to UV light, while on the red side, it relates to infrared light.

In conclusion, several criteria are thus taken into account for the measurement results.

In particular those concerning 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.

Measuring equipment to assess photobiological risk

radiometric bench EVERFINE OST-300

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

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

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