Technical knowledge：Professional surge immunity testing helps your products withstand lightning strikes and perform stably worldwide!
Electromagnetic compatibility (EMC) is a necessary condition for the design and market launch of electronic products. All countries around the world have formulated relevant regulations, requiring products to pass professional tests to meet standards. SWCT's EMC laboratory offers comprehensive testing services, covering a wide range of test scenarios and equipment configurations, to ensure that customers' products meet international regulatory requirements.
Surge Testing: The "High Voltage Examination" in EMC
As a core project in electromagnetic compatibility (EMC) testing, surge testing simulates the impact of lightning strikes (indirect lightning) in nature and voltage changes caused by large switch operations in power supply lines on power supply lines and communication lines.
● Test Waveforms: 1.2/50 μs combined wave and 10/700 μs combined wave, accurately replicating real surge impacts.
● Test Levels: 0.5 kV to 15 kV (Coview Certification Laboratory can reach 15 kV high voltage, covering the most demanding environmental requirements).
● Test Ports: Comprehensive coverage of power, signal, and communication ports.
- Pass Criteria: The equipment functions normally without faults or damage after high-voltage impact.
- Fail Risk: Direct failure or performance degradation, potentially leading to rejection in the international market.
The Global Significance of Surge Testing
Most countries have strict requirements for the surge resistance of electronic devices. For example:
● Basic standards:
IEC 61000-4-5 (General Guidelines) EN 61000-4-5
GB/T 17626.5
● Industry standards:
Household appliances (EN 55014-2), information technology (EN 55035), lighting (EN 61547), etc.
If enterprises fail to pass the test, their products may face risks such as recall and ban on sale!
We offer professional surge testing services to safeguard your products and help enterprises break through technical barriers:
● Covered products: Information technology equipment (ITE), industrial controllers, home appliances, lighting, etc.
● Equipment capabilities: 15kV high-voltage testing, precise simulation of real interference scenarios.
● Authoritative certification: In accordance with IEC/GB/EN standards, one-stop access to global market entry requirements.
► Case warning: A certain brand of router, due to failing the surge test, saw a sharp increase in failure rates in areas with frequent thunderstorms and was eventually required to be withdrawn from the market. Is your product ready for "surge protection"?
In the field of electromagnetic compatibility, SWCT has always provided one-stop EMC testing and certification solutions for enterprises with professional technology, precise testing and efficient services. Whether it is consumer electronics, automotive electronics, industrial equipment or medical devices, we have complete testing facilities and rich testing experience to help your products smoothly enter the global market.
