Automotive EMC Support for OEMs and Suppliers
Vehicle manufacturers and component suppliers need EMC evidence that reflects the product’s electrical architecture, operating modes and intended markets. Stancer Testing-Lab helps OEMs, Tier 1 suppliers and automotive development teams plan emissions, immunity and electrical disturbance evaluations.
Our ISO/IEC 17025-accredited EMC and RF laboratory combines a dome-shaped semi-anechoic chamber with automated measurements and practical engineering support. The chamber accommodates small to mid-size vehicles; we confirm access, dimensions, weight and operating requirements before booking.
For detailed methods and capabilities, explore our automotive EMC testing service. Radar sensors and connected modules can also require coordinated automotive radar testing and RF and wireless testing. We agree the applicable standards, OEM specifications and accredited methods with your team.

Testing starts with the system you intend to deliver. Representative harnesses, loads, software, power supplies and support equipment help make the results useful for your design and compliance decisions.
ECUs, sensors and electronic subassemblies
Component EMC programs that account for harness layout, interfaces, simulated loads and the relevant OEM specification.
Electric and hybrid vehicle electronics
Converters, controllers and associated electronics, with attention to switching noise, power requirements and safe operation of the test setup.
Radar, telematics and connected modules
RF and EMC test planning around radio technology, operating frequency, antennas and the product’s installation configuration.
A clear route from test planning to reports

- Prepare the configurationAgree harnesses, loads, operating modes, monitoring and safety needs.
- Evaluate and investigatePerform the agreed measurements and document any disturbances or design changes.
- Build the evidenceReport the tested configuration, methods, measurements and observed responses.
Choose the Right Automotive EMC Test Program
UNECE R10, CISPR and ISO methods serve different purposes. Select the test program by product type and approval objective, then confirm the relevant edition, OEM limits and laboratory scope.
| Reference | What it addresses |
|---|---|
| UNECE Regulation No. 10 | Electromagnetic compatibility requirements for applicable vehicle and electrical/electronic subassembly approval programs. |
| CISPR 12 / CISPR 25 | Radio disturbance measurements for protection of off-board receivers / on-board receivers respectively. |
| ISO 11451 / ISO 11452 | Vehicle / component immunity methods respectively; the applicable part is selected for the test program. |
| ISO 7637-2 / ISO 16750-2 | Conducted electrical transients on supply lines / electrical loads and supply conditions. |
| ISO 10605 | Electrostatic discharge evaluation for applicable automotive equipment and vehicle programs. |

How does vehicle testing differ from component EMC testing?
Vehicle-level tests evaluate the assembled vehicle in agreed operating conditions. Component testing evaluates an electrical/electronic subassembly with representative harnesses, power supplies, loads and interfaces. UNECE R10 and applicable CISPR or ISO methods may be relevant to either program, but the setups and objectives differ. Our automotive EMC testing team can help define the appropriate configuration.
What is the difference between CISPR 12 and CISPR 25?
CISPR 12 addresses radio disturbances with the objective of protecting receivers outside the vehicle. CISPR 25 addresses protection of receivers installed on board. The applicable measurements, limits and configurations should be selected for the vehicle or component program and relevant OEM requirements.
Which standards apply to automotive RF immunity?
ISO 11451 methods address vehicle-level immunity; ISO 11452 methods address components. For example, ISO 11452-2 uses an absorber-lined shielded enclosure, while ISO 11452-4 addresses harness excitation methods. Frequency range, test level, modulation and monitored functions are agreed for the applicable method and specification.
How are automotive transient and supply tests selected?
Start with the equipment’s supply architecture and the applicable OEM or regulatory test plan. ISO 7637-2 and ISO 16750-2 address different electrical disturbance and load conditions. Pulse selection, severity, operating state and acceptance criteria depend on the equipment; a single generic pulse list does not describe every program.
Do automotive products need ESD testing?
ISO 10605 may be relevant to automotive electrostatic discharge evaluation. Accessible surfaces, discharge points, operating conditions and acceptance criteria should be defined for the product. Stancer can coordinate ESD evaluation with the broader automotive EMC testing program.
When are harmonics, flicker, surge and burst tests relevant?
Charging or other mains-connected operating conditions may introduce requirements beyond the vehicle’s low-voltage electrical network. Harmonic current, voltage fluctuation, surge or electrical fast transient tests should be selected from the applicable requirements for that configuration. They should not be treated as a universal test set for every automotive component.
Can Stancer support electric and hybrid vehicle electronics?
Yes. We can review EMC test programs for vehicle controllers, converters and related electronic subassemblies. Share the supply voltage and current, cooling needs, interface details, representative loads and operating modes. Confirm the required setup and safety arrangements with the laboratory before shipping.
Can automotive EMC problems be investigated before formal testing?
Yes. EMC pre-compliance testing can focus on emissions peaks, immunity responses or the effect of a proposed filter, shielding or harness change. Documenting the configuration before and after a change helps your engineers assess the next design step. Development measurements do not guarantee a later compliance pass.
How do we prepare samples and harnesses for testing?
Provide the test specification, electrical ratings, harness drawings, representative loads, connectors, software and support equipment. Define monitored functions and acceptance criteria, and identify handling or vehicle-operation constraints. Our automotive test preparation checklist helps organize these details.
Does EMC testing provide E-Mark or wireless certification?
Laboratory reports provide technical evidence; they do not themselves grant an E-Mark or radio equipment authorization. The applicable approval process involves the relevant authority or certification body. Stancer supports testing and documentation, and can coordinate RF and wireless testing or automotive radar testing where relevant to the product.
