EMI/EMC Standards IEC 61000-4-2, ITU-T K.21

We conduct testing strictly in accordance with the latest international guidelines to ensure your product meets global acceptance criteria:

• IEC 61000-4-2: Electromagnetic compatibility (EMC) – Part 4-2: Testing and measurement techniques – Electrostatic discharge immunity test.
• ITU-T K.21: Resistibility of telecommunication equipment installed in customer premises to overvoltages and overcurrents.

These standards are mandatory for a wide range of consumer and industrial electronics, specifically those connecting to telecom networks or prone to static buildup:

• Customer Premises Equipment (CPE): Modems, Routers, ADSL/VDSL gateways, and Set-top boxes.
• Telephony Devices: Cordless phones, VoIP phones, and Fax machines.
• IT Equipment: Laptops, PCs, and Servers with communication ports.
• Industrial Electronics: Control panels and HMIs requiring high ESD immunity.

Our laboratory setup utilizes advanced simulators to replicate real-world electrical stress scenarios:

For IEC 61000-4-2 (ESD):

• Contact Discharge: Direct application of voltage (up to ±8kV) to conductive surfaces.
• Air Discharge: Proximity application (up to ±15kV) to insulating surfaces and slots.

For ITU-T K.21 (Surge/Resistibility):

• Lightning Surge Simulation: Testing ports against high-energy transients (1.2/50 µs and 10/700 µs waveforms).
• Power Induction & Contact: Simulating accidental contact with AC mains lines.

Your test reports are backed by the highest levels of quality assurance. Our partner laboratories hold ISO/IEC 17025 accreditation, recognized by major regulatory bodies including:

• NABL (National Accreditation Board for Testing and Calibration Laboratories).
• ILAC (International Laboratory Accreditation Cooperation) Mutual Recognition Arrangements.

We understand that time-to-market is critical. Our streamlined testing process ensures rapid delivery:

• Standard Turnaround Time (TAT): 5 to 7 working days (post-setup verification).
• Expedited Services: Priority slots available for urgent compliance needs (2-3 working days).

To ensure a smooth testing process without interruptions, please provide the following:

• Functional Units: 1 to 2 fully operational samples of the Device Under Test (DUT).
• Accessories: All necessary power adapters, cables, and remote controls.
• Operation Mode: Instructions or software to keep the device in its typical operating state during testing.

Pricing is optimized based on the complexity of the device and the specific test levels required (Basic vs. Enhanced).

Please contact our sales team with your product specifications for a tailored, competitive quotation.

To facilitate the testing and report generation, the following documents are required:

• User Manual: Operating instructions and safety guides.
• Circuit Diagram/Schematics: For analysis of protection components (varistors, GDTs, etc.).
• Block Diagram: Showing the functional layout of the device.
• General Specifications: Power ratings, port details, and intended environment.
