EN 60598 Thermal Endurance Testing of Luminaires
The European standard EN 60598 specifies general requirements and test methods for luminaires. One of the key tests within this standard is the thermal endurance testing, which ensures that luminaires can withstand extreme temperatures without compromising their integrity or performance. This test is essential in ensuring product safety, reliability, and compliance with international regulations.
This service involves subjecting light fittings to controlled temperature variations over a specified period to evaluate their resistance to heat stress. The luminaire must maintain its functional integrity under these conditions, including the continued operation of all electrical components and the stability of the optical performance. This test is critical for products intended for use in environments where extreme temperatures may be encountered.
The testing process begins with careful preparation of the specimen according to EN 60598:2017, which provides detailed instructions on how to prepare luminaires for thermal endurance tests. The luminaire is placed into a temperature chamber and subjected to cycles of heating and cooling that simulate real-world conditions it may encounter in use.
The primary purpose of this test is to ensure the durability and reliability of light fittings under varying temperatures, thereby increasing consumer safety and satisfaction. Compliance with this standard not only ensures product quality but also helps manufacturers meet regulatory requirements and avoid potential recalls or legal issues.
Thermal endurance testing is crucial for products like street lamps, industrial lights, and other luminaires used in environments where temperature fluctuations can be extreme. This test evaluates the luminaire’s ability to maintain its functional integrity under these conditions.
| Cycle | Temperature Range (°C) | Dwell Time (hours) | Repetition Count |
|---|---|---|---|
| 1 | -20 to +75 | 4 hours | 3 |
| 2 | +75 to -20 | 4 hours | 3 |
The test cycles are designed to simulate real-world conditions, ensuring that the luminaire can withstand significant temperature changes without compromising its performance. The luminaire must pass all tests within these specified parameters to meet EN 60598 requirements.
| Measurement Points | Parameters Measured | Acceptance Criteria |
|---|---|---|
| Thermocouples | Temperature, Voltage, Current | Voltage and current should remain within ±10% of nominal values. |
| Luminous Flux Sensors | Luminous Flux Output | Luminous flux output must not decrease by more than 20% after the test. |
The acceptance criteria for this testing are stringent, ensuring that only high-quality products pass. Compliance with these standards is crucial for manufacturers and suppliers who wish to ensure their products meet international quality benchmarks.
