EMC Testing Solutions for Aerospace, Defence, Automotive & Commercial Applications
Complete EMC Compliance Testing: Immunity, Emissions and Test Environments
APC Technology Group provides comprehensive EMC testing solutions from pre-compliance through to full certification. Whether you need in-house test capability or a turnkey laboratory installation, our team delivers expert guidance backed by world-leading equipment partners.
What is Electromagnetic Compatibility (EMC)?
EMC (Electromagnetic Compatibility) testing ensures electronic devices can function correctly in their electromagnetic environment, neither causing unacceptable interference (emissions) nor being affected by it (immunity). It verifies that a product doesn't disrupt other equipment (such as radios and phones) and can withstand electromagnetic disturbances, a crucial step for regulatory compliance (such as CE marking) and safe market release.
Why Bring EMC Testing In-House with APC?
Below are some examples of how APC can support you with your test setup and equipment requirements to fit your long-term testing needs.

Emissions Testing
Emissions testing measures the electromagnetic noise your equipment generates. Products must meet strict limits to prevent interference with other devices and comply with CE marking, FCC and international standards.
Radiated Emissions
CISPR 16 / EN 55032
Measure electromagnetic noise conducted through power and signal cables. Testing 9 kHz to 30 MHz.
Conducted Emissions
CISPR 16 / EN 55032
Measures noise transmitted through power cables and signal lines using LISN and a spectrum analyser.
Immunity / Susceptibility Testing
Immunity testing evaluates how well your equipment withstands electromagnetic disturbances. From electrostatic discharge to power line transients, these tests ensure reliable operation in real-world environments.
ESD Testing
EN 61000-4-2
Electrostatic discharge immunity - simulates static electricity events from human contact and equipment.
EFT/Burst Testing
EN 61000-4-4
Fast transient burst immunity tests resilience to repetitive high-frequency switching noise.
Surge Testing
EN 61000-4-5
Surge immunity - simulates lightning strikes and power switching transients on mains and data lines.
Voltage Dip Testing
EN 61000-4-11
Voltage dip, interruption and variation immunity - tests behaviour during power quality disturbances.
Conducted Immunity (BCI)
EN 61000-4-6
Bulk current injection and conducted RF immunity - tests cable-conducted interference resilience.
EMC Test Environments
Accurate EMC testing requires controlled electromagnetic environments. From fully-shielded anechoic chambers to open area test sites, APC designs and installs test facilities tailored to your requirements.
Anechoic Chambers
RF-absorbing chambers simulate free-space conditions for accurate antenna & emissions tests.
Semi-Anechoic Chambers
Chambers with absorber walls and a reflective floor for standard emissions testing.
Shielded Rooms
Designed to prevent the entry or exit of electromagnetic radiation for clean measurements.
GTEM Cells
Modern EMC test environments are used for emission and immunity testing under EN 61000-4-20 & 21.
