EMI/EMC Standards IEC 61000-4-5

While IEC 61000-4-5 is the parent international standard, compliance is often mandated through various harmonized versions depending on your target market:

• International: IEC 61000-4-5 (Electromagnetic compatibility - Testing and measurement techniques - Surge immunity test).
• Europe: EN 61000-4-5 (Harmonized under the EMC Directive).
• India: IS 14700 (Part 4/Sec 5) (Adopted by BIS).
• Generic References: Often called out in generic standards like IEC 61000-6-1 (Residential) and IEC 61000-6-2 (Industrial).

Surge immunity is rarely optional. It is a mandatory requirement for almost any device connected to a mains power supply or external data lines. Key product categories include:

• Lighting: LED Drivers, Luminaires, and Street Lighting (often require higher surge levels, e.g., 4kV or 6kV).
• Industrial: PLCs, Motor Drives (VFDs), Industrial Sensors, and Control Panels.
• Consumer Electronics: Household Appliances (Washing Machines, Refrigerators), Power Adapters.
• Medical: Patient Monitoring Systems, Diagnostic Equipment (requiring high reliability).
• Telecom: Modems, Routers, and Switching Equipment.

Our testing facility is equipped to handle the full spectrum of severity levels defined by the standard. The scope includes simulating various installation environments:

Test Levels:

• Class 1 & 2: Protected/Partial environments ($0.5$ kV to $1.0$ kV).
• Class 3: Industrial environments ($1.0$ kV to $2.0$ kV).
• Class 4: Severe/Outdoor environments (Up to $4.0$ kV).

Coupling Modes:

• Line-to-Line: Direct injection between phases or phase-to-neutral.
• Line-to-Ground: Injection between phase/neutral and protective earth.

Ensure your test reports are globally recognized. Our testing is conducted under strict adherence to ISO/IEC 17025 quality management systems.

• NABL Accredited Lab: Reports are valid for BIS/TEC compliance in India.
• ILAC MRA Signatory: Reports are accepted internationally for CE (Europe), FCC (USA), and other global certifications.

Surge testing is a destructive/stress test, but the setup is streamlined.

• Standard Testing: 3 to 4 Working Days (including setup, calibration, testing, and reporting).
• Expedited Service: 24 to 48 Hours (available upon request for urgent deadlines).

Note: If the product fails (e.g., blown fuse or MOV), troubleshooting time will be additional.

To ensure a smooth testing process without delays, please provide:

• Quantity: 1 Fully Functional Unit (EUT - Equipment Under Test).
• Advice: Since this is a high-energy test, providing 1 spare unit is highly recommended in case of component failure during the initial setup.
• Cabling: All necessary power cords and interconnecting cables (at least 1 meter in length).
• Auxiliary Gear: If the device needs a specific load or support equipment to operate (e.g., a laptop for a USB device), please include it.

Pricing is competitive and depends on the complexity of the product and the required voltage levels.

• Basic AC/DC Devices: Standard pricing applies.
• Three-Phase / High-Voltage Equipment: Cost may vary due to complex coupling setups.

To generate a valid test report, the following documents are required prior to testing:

• General: User Manual and Technical Specification Sheet.
• Technical: Circuit Diagram / Block Diagram (crucial for identifying surge protection components like MOVs/GDTs).
• Identification: Copy of the Product Marking Label (Rating Plate) showing input voltage, current, and model number.
