EMC Testing Services: Emissions & Immunity
Emissions testing measures electromagnetic interference (EMI) produced by your equipment. Immunity testing evaluates whether it continues to function as required when exposed to specified disturbances. An EMC compliance testing program brings together the relevant evaluations for your product, intended environment, ports and destination markets.
Radiated & Conducted RF Immunity
Controlled RF exposure assesses the equipment’s response while agreed functions are monitored. Explore radiated immunity and conducted immunity.
ESD, Burst & Surge
Electrical disturbances can produce resets, communication errors or other functional responses. We apply the selected methods and record behaviour against the agreed criteria. Explore ESD testing and transient testing.
Power Quality & Low-Frequency Immunity
Programs can include harmonics and flicker, power-frequency magnetic fields and voltage dips and interruptions, where applicable.
Product Standards in Our Accreditation Scope
A product or product-family standard establishes the requirements for a particular category. It may call up several basic test methods. The references below are selected examples from Stancer’s scope; the applicable edition and configuration are confirmed for your project.
For industrial, scientific and medical equipment, CISPR 11 and EN 55011 address emissions within their respective applicability. Multimedia equipment EMC testing can combine CISPR 32 / EN 55032 emissions with CISPR 35 / EN 55035 immunity. Measurement, control and laboratory equipment is evaluated using IEC 61326-1 and relevant listed parts of IEC 61326-2. We check the product classification and intended environment before selecting the requirements.

A Laboratory Equipped for Practical Test Setups
Our dome-shaped SAC PLUS semi-anechoic chamber offers usable dimensions of 8.5 × 5 × 6 m, a 2 × 2 m door and EUT capacity up to 2,000 kg. An automated antenna tower and turntable use Rohde & Schwarz ELEKTRA and dedicated control systems.
Instrumentation includes a Rohde & Schwarz ESW receiver with coverage to 44 GHz, RF signal generators, high-power amplifiers across applicable bands up to 6 GHz, LISNs, power meters, antennas, transient generators and harmonic/flicker systems.
Applicable setups support 200 A, three-phase EUT current and RF immunity fields up to 200 V/m. These are maximum capabilities, not levels available for every method or frequency. Specialist RF measurement arrangements extend to 325 GHz; the selected test program identifies the usable range and accredited activities.
The chamber uses site-performance verification for NSA, field uniformity and sVSWR as applicable. An RFI trap supports cable feedthroughs, while built-in filtering and additional setup filtering can help control external conducted noise. Explore the chamber and laboratory capabilities.
From Requirements Review to a Documented Test Report
- Establish the requirements. Share the product, intended environment, target markets and customer specifications. We identify the applicable methods and agree the program.
- Prepare the configuration. Confirm samples, accessories, cable arrangements, operating modes, loads and functional monitoring.
- Investigate early if needed. Pre-compliance testing helps locate emissions sources or immunity weaknesses before formal testing.
- Perform the agreed tests. Measurements and disturbance responses are recorded against the selected limits and acceptance criteria.
- Document the results. The report identifies the tested equipment, configuration, methods, conditions, results and relevant deviations.
EMC Test Preparation: What to Send Before Booking
Provide a product description, dimensions, mass, supply voltage and current, operating modes, cable and port information, accessories, firmware version, target markets and requested schedule. Include monitoring instructions and any customer test specification.
Start with our EMC & RF Client Information Sheet to describe the equipment and test configuration. For specialist applications, use our medical EMC preparation checklist or automotive EMC preparation checklist for those applications.
Testing Evidence for Your Target Markets
The required route depends on the product and destination. Stancer supports applicable EMC testing and technical documentation for FCC requirements, ISED requirements, CE marking and VCCI conformity.
Radio, electrical safety and other product requirements are identified separately where relevant. A test report documents the agreed evaluation; certification or approval proceeds through the appropriate process. See global market access support.
EMC Testing: Your Questions Answered
What is electromagnetic compatibility testing?
Electromagnetic compatibility testing evaluates the disturbances a product emits and its ability to function when exposed to electromagnetic disturbances. The applicable product standards define the emissions limits, immunity test levels and performance criteria. The test program depends on the equipment, intended environment and target markets.
What determines EMC testing cost?
EMC testing cost depends on the applicable standards, number of tests, operating modes, ports, sample configurations and time needed for setup and functional monitoring. Bulky equipment, special power arrangements and troubleshooting can affect the program. Send your product specifications and target markets for a project-specific EMC testing quote; any design changes and retesting are agreed separately.
Which EMC standard applies to my product?
That depends on the product category, intended environment and target markets. Send those details and any customer specification so we can determine the relevant product standard and basic methods.
What is the difference between emissions and immunity?
Emissions concern disturbances produced by the equipment. Immunity concerns its response to applied disturbances. The applicable product requirements determine which evaluations are needed.
Is pre-compliance testing the same as formal testing?
No. Pre-compliance supports design investigation and troubleshooting. Formal testing follows the agreed compliance program and produces the corresponding documented results.
Can you test bulky or high-current equipment?
We review the proposed equipment against access, mass, supply and measurement requirements. Available setups include EUT capability up to 200 A, three-phase; chamber access and clearance are confirmed before booking.
Do wireless products need both EMC and RF testing?
They may. Host electronics and radio functions can have different requirements. We coordinate the applicable evaluations within the proposed program.
What happens if the equipment fails a test?
We document the result and can investigate the response with your engineering team. Any changes and retesting are agreed before proceeding, with the tested configuration recorded.
