EN 13201 Flicker Testing of Road Lighting Installations
The European Standard EN 13201 specifies requirements and test methods to evaluate flicker in road lighting installations. This standard is crucial for ensuring the safety, comfort, and performance of road users by mitigating potential hazards associated with light flicker.
Flicker can be defined as a modulation or fluctuation in the luminous flux that the eye perceives. It may occur due to imperfections in the power supply, design flaws in the lighting installation, or specific operating conditions. For road lighting installations, flicker can lead to discomfort, disorientation, and even accidents. The standard aims to quantify this effect by measuring the perceived flicker level (PFL) of luminaires under various scenarios.
EN 13201 provides a comprehensive framework for testing. It includes detailed procedures for setting up test conditions, preparing specimens, and conducting tests in controlled environments. The standard also stipulates acceptance criteria that must be met to ensure the installation complies with safety and performance requirements.
The testing process typically involves placing the luminaire under controlled lighting conditions, simulating real-world driving scenarios, and measuring the perceived flicker level using a calibrated photometer. The results are then compared against established thresholds defined in EN 13201 to determine compliance.
Understanding the impact of flicker on road safety is critical for both manufacturers and authorities responsible for maintaining public infrastructure. By adhering to this standard, stakeholders can ensure that their lighting installations meet stringent quality standards, thereby enhancing road user safety and comfort.
| Standard | Description |
|---|---|
| EN 13201:2004 | European Standard for flicker testing of road lighting installations |
| ISO/IEC 80079-1:2017 | International standard on the classification and testing of electrical equipment in potentially explosive atmospheres, relevant to luminaire design |
Why It Matters
The importance of flicker testing cannot be overstated. In environments where visibility is critical, such as roads and highways, even minor fluctuations in light can have significant impacts on driver safety and comfort. Flicker can cause visual discomfort, leading to reduced attention spans and increased risk of accidents.
- Flicker can cause eye strain and fatigue for drivers
- It may lead to misjudgment of distances and speeds
- Prolonged exposure can result in headaches and other health issues
- In severe cases, it could contribute to collisions or near misses
The standard ensures that luminaires meet stringent quality benchmarks. This not only enhances road safety but also contributes to a more harmonized approach across different jurisdictions within the European Union.
Compliance with EN 13201 is essential for manufacturers and installers of road lighting installations. It provides a uniform method for assessing flicker, ensuring consistency in quality and performance across various luminaires. This standardization benefits both end-users who can rely on consistent product performance and regulatory bodies responsible for enforcing safety norms.
Applied Standards
