Overview
IEC 62560:2011/AMD1:2015 is an important international standard amendment issued by the International Electrotechnical Commission (IEC) that addresses safety specifications for self-ballasted LED lamps used for general lighting services operating at voltages above 50 V. This amendment consolidates the corrigendum issued in June 2015, providing updated requirements and testing procedures to enhance lamp safety, mechanical integrity, and photobiological risk management.
The standard is vital for manufacturers, designers, and safety assessors involved in the production and certification of LED lamps, ensuring compliance with internationally recognized safety norms. It helps mitigate risks related to electrical, mechanical, and photobiological hazards while providing guidance on labeling and design considerations.
