EN 62471 Thermal Safety Testing for Photobiological Risk
The European Standard EN 62471-1:2018 sets forth essential criteria to ensure the photobiological safety of luminaires and similar products. This standard is crucial in mitigating risks associated with exposure to light from artificial sources, particularly the potential for thermal injuries caused by laser-like emissions or intense visible light.
The standard specifically addresses the photobiological risk classification based on radiant power and spectral distribution across various wavelengths. It provides a harmonized framework that aligns with international standards such as ISO 21835:2016, ensuring that manufacturers can comply globally while adhering to local regulations.
Thermal safety testing under EN 62471 is essential for several reasons:
- To prevent burns and other thermal injuries caused by prolonged or excessive exposure to light sources.
- To ensure compliance with regulatory requirements in the European Union and beyond.
- To safeguard consumer health and safety, especially for products used in close proximity or for extended periods.
The testing process involves a series of controlled experiments designed to simulate real-world conditions where users might be exposed to light from the product. This includes measuring the radiant power at different wavelengths and ensuring that it falls within acceptable limits as defined by the standard.
Our laboratory adheres strictly to EN 62471 methodologies, employing state-of-the-art equipment to ensure accurate and reliable results. Our team of experts ensures that every step of the testing process is conducted with precision, from initial consultation through final reporting.
| Parameter | Description |
