IEC 60335 Photobiological Safety Testing of Household Lighting Equipment
The International Electrotechnical Commission (IEC) standard IEC 60335-2-81 defines photobiological safety requirements for household lighting equipment. This standard is crucial because it ensures that the light-emitting devices do not pose a risk of causing ocular or skin irritation, cancer, or other health hazards due to excessive blue light and ultraviolet (UV) radiation.
Photobiological safety testing focuses on evaluating the optical hazard classification (OHC) of lighting equipment. The OHC is determined based on the emission levels of visible light, near-ultraviolet (near-UV), and blue light. This evaluation helps manufacturers design products that are safe for consumers to use without causing any adverse health effects.
Testing typically involves exposing the lighting equipment to a photometer with a defined spectral response curve that matches human visual sensitivity and the biological effects of the emitted radiation. The exposure time is critical, as it must be long enough to capture the full range of potential hazards but short enough to avoid any real risk during testing.
Preparation for this test includes selecting appropriate specimens based on the specific types of lighting equipment being tested (e.g., LED lamps, fluorescent tubes). The specimens are then positioned in a controlled environment that simulates typical usage conditions. This setup ensures accurate and reproducible test results.
The testing apparatus used is highly specialized. It comprises a photometer capable of measuring light emissions across the relevant wavelengths and a radiation meter to quantify UV and blue light levels. The equipment must meet precise calibration requirements set forth in IEC standards to ensure accuracy.
Once testing is completed, detailed reports are generated that include optical hazard class (OHC) determinations, specific emission limits for each wavelength range, and any other relevant data. These reports serve as a critical resource for manufacturers to ensure compliance with regulatory requirements and provide reassurance to end-users about product safety.
