From now on, the laboratory will provide electromagnetic interference (EMI) measurement and reporting services of CNS 14115 (105th edition), which is suitable for emergency lighting and general lighting products. In line with the revision schedule of the emergency lighting accreditation benchmark by the competent authority since January 1, 115, we provide traceable and reproducible test results from a neutral and impartial third-party standpoint to assist manufacturers in completing compliance verification and design confirmation.
⚙️Overview of measurement capabilities and equipment
- Standard category: Conduct conduction disturbance and radiation electromagnetic disturbance tests according to the measurement methods and limits of CNS 14115 (105th edition).
- Test equipment
- Measurement receiver (with quasi-peak (QPEAK), average (AVG) and PEAK (PEAK) scanning functions)
- Power supply (MS), V-type artificial power network (LISN), heterosymmetric artificial network (AAN)
- Radiation measurement three-direction loop antenna, coupling/decoupling network (CDN)
- Monitoring and recording system (measurement screenshots, spectrum data, test configuration and status records)
- Test frequency range and purpose
- Conduction disturbance test frequency range: 9k~30MHz
- Purpose of the test: Whether electromagnetic interference will be transmitted to the power grid or other equipment through the power cord or signal line.
- Radiation disturbance test frequency range: 30M~300MHz
- Purpose of the test: Whether the unnecessary electromagnetic energy emitted from the shell or antenna into the air will cause interference to other products.
- Conduction disturbance test frequency range: 9k~30MHz
- Measurement traceability: The test instruments are checked regularly in accordance with regulations, and the verification certificate and uncertainty data are kept; the measurement settings and environmental conditions are recorded throughout the process to ensure that the results can be reproduced.
🔍 Applicable products and measurement endpoint range
- Applicable products: Emergency lighting, indoor and outdoor lighting equipment, LED drivers and other lighting controllers, etc.
- Measurement end point: The power supply terminal, load, control or communication terminal need to confirm the test terminal according to the actual design of the product and the formulation of the standard provisions.
🔬 Test process (practical version)
- Application for opening a case: Confirm product specifications, confirm the location of measurement endpoints, power supply conditions and applicable regulations; establish test plans and evaluation criteria.
- Confirm and check before measurement: Perform waveform and system verification and confirmation according to standards (measure receiver settings, configure LISN/CDN, three-direction loop antenna, etc.).
- Formal measurement: Perform confirmation in accordance with the sample layout, test frequency range, scanning spectrum and number of repetitions specified in the standard.
- Determination of measurement results: After the test is completed, a report will be issued against the limit requirements specified in the standard.
- Document report output: Includes test layout, setting parameters, spectrogram, frequency and end-point items, result determination and remarks.
ISO 17025 Quality and Compliance Commitment
- Neutrality and confidentiality: Operate in accordance with laboratory procedures, and the results are not affected by commercial interests; customer information and test records are kept confidentially in accordance with the contract.
- Safety and risk control: For samples with power storage or high power, segmented power-up, current limiting and protective measures are used to reduce the risk of unexpected damage.
️️5. Pre-requirements for case opening application and testing items
- Product model and specification information
- List of test endpoints, power supply specifications and operating instructions (including load conditions)
- If it is an emergency light, please provide an approved product specification
- Required report format (general PDF or TAF logo report)
