BQCIS

Assuring Reliable Function in the Electromagnetic Environment

Electromagnetic Compatibility (EMC) testing ensures that electrical and electronic devices operate as intended in shared environments — without causing or being affected by electromagnetic interference.

BQCIS provides accredited EMC testing under EN 55032, EN 61000-4, and IEC 61326 frameworks to demonstrate compliance with the EMC Directive (2014/30/EU) and related global standards.

From pre-compliance screening to full certification support, BQCIS engineers assess both emissions and immunity across radiated, conducted, and transient interference domains. Our facilities are equipped with shielded chambers, line impedance networks, and spectrum analyzers for precision measurements.

Key Activities in EMC Testing

Radiated Emission Testing

Measurement of electromagnetic fields emitted from the device under test (DUT) to ensure compliance with CISPR and FCC limits.

Conducted Emission Testing

Assessment of noise levels transmitted through power and signal lines using LISN and EMI receivers.

Electrostatic Discharge (ESD)

Verification of immunity to static discharges per IEC 61000-4-2, ensuring robust user interface performance.

Radiated Immunity Testing

Exposure of DUT to controlled RF fields to confirm proper function under electromagnetic stress.

Surge & Transient Immunity

Evaluation of device resilience to voltage spikes, surges, and EFT bursts on power and communication lines.

Harmonic & Flicker Analysis

Measurement of current harmonics and voltage flicker for grid-connected equipment under IEC 61000-3 standards.

EMC Pre-Compliance Scanning

Early design-stage evaluation to identify emission sources and optimize shielding or filtering solutions.

Test Documentation & Certification

Generation of test reports for CE, FCC, and CB scheme applications under ISO/IEC 17025 accreditation.

Conducted Immunity Testing

Assessing the product's ability to withstand electromagnetic disturbances conducted along its power and data lines.

Success Story

EMC Qualification for Smart Metering System

The Challenge:

A smart metering manufacturer required EMC validation for 5G-enabled energy meters to meet CE and UKCA compliance.

Our Solution:

BQCIS performed full radiated and conducted emission tests, ESD, EFT, and surge immunity per IEC 61000-4 series. Design improvements were verified with pre-compliance scans.

The Result:

All models passed with Class B emission limits and 4 kV immunity levels. Product gained EMC marking and European market access within 6 weeks.
