Electrical Safety for Photobiological Effects: IEC 62471 Testing
IEC 62471 is an international standard that specifies the requirements for evaluating the photobiological safety of electrical and electronic products. This standard is widely accepted as a global benchmark for ensuring the safety of lighting devices, displays, and other equipment from potential harm caused by electromagnetic radiation.
Legal and Regulatory Framework
The IEC 62471 standard is part of the International Electrotechnical Commissions (IEC) series of standards that cover electrical safety. This standard is harmonized with European Union directives, such as the Low Voltage Directive (LVD), the Electrical Equipment Safety Directive (EESD), and the Restriction of Hazardous Substances in Electrical and Electronic Equipment (RoHS) directive.
International and National Standards
The IEC 62471 standard is based on international standards from organizations like ISO, ASTM, EN, TSE, and others. Some notable examples include:
Standard Development Organizations
The IEC is responsible for developing standards that cover electrical safety, including photobiological effects. This includes:
