Two product lines cover the full range of EMC type-approval and pre-compliance work — from component and module testing through full-vehicle qualification.
9 × 6 × 6 m fully-equipped chamber for CISPR 25 component testing, EN 55032 / 55035 ITE, IEC 61000-4-3 radiated immunity, and ISO 11452-2 ALSE — 30 MHz to 18 GHz, ≥ 100 dB shielding, 3 m measurement distance.
Turnkey type-approval chambers in two variants — Regular (passenger cars, motorcycles, vans) and Long (buses, heavy trucks, trailers, agricultural tractors). Engineered to UN ECE R10 Rev.7, CISPR 12 / 25 / 36, ISO 11451 / 11452, ISO 7637, and major OEM specifications.
TESTUPS also builds custom-sized EMC anechoic chambers for specialist test envelopes — including 3 m and 10 m measurement-distance configurations, hybrid ferrite + pyramid loading, and reverberation chambers. Talk to us about your application.
Welded-steel shielded enclosure with hybrid ferrite-tile and pyramidal-absorber lining on every interior wall and ceiling. Built for radiated emissions, radiated immunity, and ALSE-method automotive testing — calibrated, validated, and signed off by an ISO/IEC 17025 lab.
This 9×6×6 m semi-anechoic chamber (SAC) is configured for the ALSE method defined in CISPR 25 and the radiated-immunity setups in IEC 61000-4-3 and ISO 11452-2. Floor remains a conductive ground plane; walls and ceiling are fully covered with hybrid absorbers — sintered ferrite tiles for the 30 MHz–1 GHz band, pyramidal foam stacked over the ferrite to extend absorption past 18 GHz.
The shell is a fully-welded modular galvanised-steel pan-panel system with a continuous RF-gasketted pneumatic door. Validated NSA, sVSWR, field uniformity, and shielding effectiveness across the full frequency range, with documented results delivered before site acceptance.

Every chamber TESTUPS delivers is a single mechanically- and electrically-bonded assembly — shell, absorbers, door, HVAC, lighting, and grounding — designed and signed off as one system.
Modular galvanised steel pan-panel construction. Continuous welded seams, RF-gasketted door, fiber-optic and waveguide-below-cutoff feedthroughs.
Sintered ferrite tiles cover 100% of inner walls and ceiling, layered with pyramidal polyurethane foam to extend absorption to 18 GHz and beyond.
324 m³ of usable volume. Ø 3 m quiet zone, 3 m measurement distance, room for full vehicle, 5-axis bench, or harness setup.
Pre-engineered mounts for fiberglass antenna mast (1–4 m) and Ø 2 m flush-mount turntable, with cable trenches and fiber feed.
1.2 × 2.1 m clear opening, double knife-edge RF gasket, electromechanical interlock, panic-release, ≥ 100 dB seal performance.
Waveguide-honeycomb ventilation panels and EMI-filtered LED lighting maintain ≥ 100 dB shielding while delivering 18 °C–24 °C, 30–70 % RH.
A semi-anechoic configuration: floor remains a conductive ground plane (CISPR 25 §6.3); the five remaining surfaces are 100% covered with the hybrid stack below.
SINTERED · 100 × 100 × 6.7 mm
NiZn sintered ferrite tiles bonded directly to the shielded wall. Provide reliable absorption below 200 MHz where pyramidal foam alone is too thin to be effective. Non-flammable, dimensionally stable, no off-gassing.
CARBON-LOADED PU · 600 mm tall
Carbon-loaded polyurethane foam pyramids stacked over the ferrite layer. Dissipates higher-frequency energy through resistive loading and geometric impedance matching. Treated for fire retardance and dust suppression.
Acceptance package includes raw measurement data, calibration certificates, and a third-party validation report from an ISO/IEC 17025 accredited service provider.
Performed on-site after installation by a third-party ISO/IEC 17025 accredited validator. Results are bundled with calibration certificates into a single sign-off package.
A single accountable team owns the build from RFQ through to first calibrated measurement.
