IEC 60598-2-21 Ed.3:2018 is a technical standard published by the International Electrotechnical Commission (IEC) that specifically focuses on luminaires for emergency lighting. It provides guidelines and requirements for the design, construction, labeling, and testing of these luminaires to ensure their safe and effective operation during emergency situations.
Design and Construction Guidelines
The standard outlines various design and construction guidelines to ensure the reliability and functionality of emergency luminaires. This includes specifications for materials, components, wiring, and insulation. The aim is to prevent any potential hazards such as electric shocks or fire risks. Additionally, the standard emphasizes the importance of adequate protection against ingress of water and dust, which is crucial for the durability and safe operation of the luminaires.
Labeling Requirements
IEC 60598-2-21 Ed.3:2018 also provides clear instructions on the labeling requirements for emergency luminaires. These labels are essential for proper identification, installation, and maintenance. The standard specifies that the labels should include important information such as manufacturer details, rated voltage and current, emergency operating mode, and any specific precautions or warnings. By following these labeling guidelines, users can easily understand the features and characteristics of the luminaires.
Testing and Compliance
To ensure compliance with the standard, manufacturers must subject their emergency luminaires to thorough testing. This includes electrical safety tests, performance tests, and environmental tests. The standard defines specific test procedures and conditions to evaluate parameters like insulation resistance, mechanical strength, light output, battery performance, and operating temperature range. Compliance with these rigorous testing requirements ensures that the luminaires meet the safety, reliability, and performance criteria set by the standard.
