ISO 30061 Spectral Performance Testing of Emergency Lighting
The ISO 30061 standard is designed to evaluate the spectral performance of emergency lighting systems, ensuring they meet stringent requirements for visibility and safety in emergencies. This service involves detailed analysis of light spectra emitted by luminaires under various operating conditions, including steady-state and flicker testing.
Emergency lighting plays a critical role in ensuring safe evacuation during power failures or other emergencies. The spectral performance of these lights is crucial as it directly impacts the visibility and recognizability of emergency signs and pathways. Compliance with ISO 30061 ensures that emergency lighting systems are not only effective but also meet international standards, enhancing public safety.
The testing process involves multiple steps to ensure comprehensive analysis:
- Preparation of the specimen in a controlled environment
- Measurement of luminous flux and colorimetric parameters under specified test conditions
- Evaluation of spectral power distribution using specialized spectroradiometers
- Assessment of flicker frequency and duration
The standard specifies detailed acceptance criteria that must be met for certification. These include:
- Luminance levels should meet or exceed specified minimum values across the entire spectrum.
- Color rendering index (CRI) must be above a certain threshold to ensure visibility of emergency signs and markings.
- Flicker frequency should not exceed 10 Hz to avoid causing discomfort or distraction during emergencies.
To prepare for testing, specimens are typically new units of emergency lighting equipment. The laboratory ensures that the environment is controlled and stable, minimizing external variables. Specimens undergo rigorous measurement processes using high-precision instruments capable of capturing spectral data with milliwatt sensitivity.
The results of ISO 30061 testing provide critical insights into the performance of emergency lighting systems under real-world conditions. Compliance with this standard is essential for manufacturers, installers, and users to ensure that their products meet international safety standards.
| Test Parameter | Description |
|---|---|
| Luminous flux (photometric measurement) | Measure the total quantity of visible light emitted by the luminaire. |
| Spectral power distribution | Determine the intensity of each wavelength within the visible spectrum. |
| Color rendering index (CRI) | Evaluate how accurately colors are rendered under the light source. |
| Flicker frequency | Measure the rate at which the light intensity fluctuates, ensuring it does not exceed safe levels. |
