GTG Group | Street Light EMC Testing and Compliance Services

What Can We Do for You?

The Lighting Testing Division of GTG Group provides specialized EMC testing services for street light enterprises to solve electromagnetic compatibility compliance challenges:

 

• Test Execution: Conduct electromagnetic interference (radiation, conduction) and electromagnetic immunity (electrostatic discharge, surge, voltage dip) tests in accordance with international/regional standards;
• Compliance Analysis: Compare EMC limit requirements across different markets such as CE (EU), FCC (USA), UKCA (UK), and RCM (Australia & New Zealand) to identify non-compliant items;
• Rectification Support: Provide EMC optimization solutions (e.g., filter circuit design, grounding rectification) to help enterprises meet standards efficiently.

Service Boundary Description:

• We do not guarantee test pass results; the final outcome depends on whether the actual electromagnetic performance of the street light product meets the standards;
• Test data is based on submitted samples and does not replace enterprises’ responsibility for production consistency;
• The cycle and cost vary depending on street light functions (e.g., with smart control/wireless modules) and test standards, subject to contractual agreements.

GMA International Certification Capability

GTG Group’s GMA team provides EMC testing and global market access linkage support for street light enterprises:

 

• EMC Compliance for Core Markets:
  • EU: Align with the CE Directive (2014/30/EU Electromagnetic Compatibility Directive) and complete testing in accordance with EN 55015 + EN 61000-6-2;
  • USA: Meet the radiated/conducted limit requirements of FCC Part 15B;
  • Asia-Pacific: Adapt to special EMC clauses of RCM (Australia & New Zealand), PSE (Japan), and KC (South Korea).
• Coverage: Support EMC compliance coordination in over 130 countries/regions, and simultaneously provide packaged services of “EMC testing + target market certification” (Data source: GTG internal statistics).

Service Process and Factors Affecting Cycles

Service Process (Standard Process)

 

Step	Core Content	Estimated Time (Routine Items)
1. Requirement Confirmation	Clarify street light type (e.g., LED/smart), target market, and standards to be met	1 working day
2. Sample and Data Submission	Provide 1-2 complete street lights (with accessories) + circuit diagrams, BOM lists	Enterprise coordination cycle
3. Test Execution	Complete EMI + EMS tests in accordance with standards and record data curves	3-5 working days
4. Report and Rectification	Issue Chinese-English test reports, mark non-compliant items, and assist enterprises in rectification	2 working days
5. Re-test and Confirmation	Conduct re-tests on key items for rectified samples to confirm compliance	2-3 working days

 

Factors Affecting Cycles

 

• Functional Complexity: Smart street lights with wireless modules (e.g., NB-IoT) require additional radio frequency interference testing, extending the cycle by 2 working days;
• Test Pass Rate: First-time test failure (e.g., excessive radiation) and subsequent re-testing after rectification will prolong the cycle;
• Special Standard Requirements: Some markets (e.g., SASO in the Middle East) require additional “voltage fluctuation immunity” testing, increasing the cycle by 1 working day.

Cases and Practices

A LED street light manufacturer exporting to Europe failed the first EMC test due to excessive radiated emissions (800MHz frequency band). GTG Group’s engineer team analyzed the issue as insufficient filtering of the driving power supply and recommended adding a common-mode inductor. The second test met the standard within 1 working day, and the CE certification was successfully obtained.

 

A smart street light enterprise needed to enter the Australian market. GTG simultaneously completed EMC testing related to RCM certification and compatibility verification of the solar charging module, avoiding the problem of “separate testing - repeated rectification” and shortening the overall cycle by 30%.

Frequently Asked Questions (FAQ)

• What is the difference between EMC testing for ordinary LED street lights and smart street lights?
  Smart street lights, with wireless modules (e.g., LoRa), require additional “radio frequency interference testing” (e.g., EN 300 220) and verification of electromagnetic interference from wireless operation on the main circuit of the street light. They have 3-4 more test items than ordinary LED street lights.

• What are the common rectification directions if EMC testing fails?
  Excessive radiation can be addressed by optimizing grounding design (e.g., increasing grounding area) or adding EMI filters; insufficient immunity can be improved by enhancing port protection (e.g., adding surge suppressors at the power supply end). Specific solutions require identifying the cause based on test data.

• How long is the validity of a street light EMC test report?
  If the street light design, circuit, and key components (e.g., driving power supply) remain unchanged, the report is valid for a long time; if there are structural or material adjustments, re-testing is required.

• Is it possible to only conduct EMC testing without other certifications?
  Yes. Enterprises can entrust EMC testing alone to obtain data (e.g., for R&D phase verification). If export is required, it is necessary to align with target market certification requirements (e.g., CE, FCC), and we can provide phased services.

• Will test samples be damaged?
  “Electrostatic discharge” and “surge” in EMC testing are destructive tests (simulating extreme scenarios) and may cause sample failure. Enterprises are advised to provide backup samples; non-destructive tests (e.g., radiation) will not damage samples.
