EN 12464 Photometric Testing of Lighting in Workplaces
The European standard EN 12464-1:2013 specifies the requirements for photometric characterization and measurement of luminaires intended to be used in workplaces. This standard ensures that lighting installations meet ergonomic, safety, and health criteria necessary for visual comfort under normal working conditions.
Photometric testing is crucial for evaluating light distribution, uniformity, color rendering index (CRI), and luminous flux. These parameters are critical in determining the suitability of luminaire types for specific work environments such as offices, factories, or healthcare facilities. The test procedure covers not only the luminaire’s performance but also its impact on human visual comfort.
EN 12464-1:2013 is part of a series of standards that include EN 12464-2 for colorimetric testing and EN 12464-3 for electrical safety checks. Together, these standards form an essential suite for the design, installation, and maintenance of workplace lighting systems.
In this service page, we will explore the scope and methodology of photometric testing according to EN 12464-1:2013, highlight the advantages that Eurolab offers in conducting these tests, provide real-world use cases, and address frequently asked questions from our clients.
Scope and Methodology
The scope of EN 12464-1:2013 is to provide a standardized approach for the photometric characterization and measurement of luminaires used in workplaces. The methodology outlined in this standard ensures that all tests are conducted under controlled conditions, thereby providing consistent and comparable results.
| Key Components | Description |
|---|---|
| Luminous Intensity Distribution | The measurement of the distribution of luminous intensity in all directions around a luminaire. |
| Color Rendering Index (CRI) | Evaluation of how well colors are rendered under different light sources compared to natural daylight. |
| Luminous Flux | Total amount of visible light emitted by the luminaire. |
| Uniformity | The evenness of light distribution across a work surface or space. |
| Glare | Evaluation of the luminance contrast between the direct and reflected light to ensure it does not cause discomfort. |
The methodology involves several key steps. Initially, the luminaire is mounted on a standard test bench with a known distance from the measurement point. The luminaire is then turned on and stabilized for at least 30 minutes before measurements begin to ensure accurate readings. A photometer equipped with an integrating sphere captures the luminous intensity distribution of the luminaire.
Color rendering tests are conducted using a set of standard color samples placed in front of the luminaire. The CRI is calculated based on how well these colors are rendered under the light source compared to natural daylight. Luminous flux and uniformity measurements are taken across predefined areas within the test chamber, ensuring that all critical zones receive adequate lighting.
Glare calculations are performed using a glare meter that measures the luminance contrast between direct and reflected light sources. The standard also includes recommendations for minimizing glare to ensure visual comfort in work environments.
