HCT America Engineering offers support with EMC automotive testing services which cover everything from ISO 11452 transients immunity, bulk current injection, and magnetic immunity to near-field emissions and portable (handy) transmitter tests. The goal is to deliver a one-stop solution for ISO Accredited Automotive EMC testing services. Located in San Jose, HCT America’s state-of-the-art Automotive EMC Testing facilities provide capabilities ranging from 100A Load Dump to 300 V/M radiated immunity testing. Supporting the Bay Area’s dynamic Electric Vehicle and Automotive Component and Systems industry, HCT America Engineering provides the only full-service Automotive EMC testing facility on the West Coast.

Why Are Automotive EMC Standards Important?

Automotive EMC testing checks the electromagnetic compatibility of the vehicle as well as all the components. It is crucial to monitor every aspect of the vehicle and determine whether any are generating electromagnetic interference (EMI). The typical car dashboard is now filled with active components that must operate without causing disruption.

Car manufacturers understand that modern vehicles can have as many as 75 different electronic modules. These are crucial elements that determine whether a vehicle is safe on the road relating to everything from braking to steering and tailpipe emissions. As such, without automotive EMI testing, it’s possible that any one of these different modules could potentially fail in your product.

EMC testing and compliance is now a crucial element for not just safety but the performance of a vehicle and ultimately the revenue stream of an automobile manufacturer or part supplier.

ISO, CISPR, and SAE mainly develop automotive EMC standards. These standards are maintained at an international level. Vehicles that market worldwide will typically reference both CISPR and ISO standards. HCT America provides testing solutions for numerous standards and regulations, including:

• ISO 11452-1: Road vehicles, Component test methods for electrical disturbances from narrow-band radiated electromagnetic energy – Part 1: General and definitions.
• ISO 11452-2: Road vehicles, Electrical disturbances by narrow-band radiated electromagnetic energy - Component test methods Part 2 - Absorber-lined shielded enclosure.
• ISO 11452-4: Road vehicles, Component test methods for electrical disturbances from narrow-band radiated electromagnetic energy – Part 4: Bulk current injection (BCI).
• ISO 11452-8: Road vehicles, Component test methods for electrical disturbances from narrow-band radiated electromagnetic energy -- Part 8: Immunity to magnetic fields.
• ISO 11452-9: Road vehicles, Component test methods for electrical disturbances from narrow-band radiated electromagnetic energy - Part 9: Portable transmitters.
• ISO 11452-10: Road vehicles, Component test methods for electrical disturbances from narrow-band radiated electromagnetic energy – Part 10: Immunity to conducted disturbances in the extended audio frequency range.
• GB/T18387-2017: Limits and test methods of magnetic and electric field strength from electric vehicles.
• ISO 10605: Road vehicles, Test methods for electrical disturbances from electrostatic discharge.
• ISO 7637-1: Road vehicles, Electrical interference by conduction and coupling Part 1 – Definitions and general considerations.
• ISO 7637-2: Road vehicles, Electrical disturbance by conduction and coupling Part 2 - Vehicles with nominal
• ISO 7637-3: Road vehicles, Electrical interference by conduction and coupling Part 3 – Electrical transient transmission by capacitive and inductive coupling via lines other than supply lines.
• IEC 62311: Assessment of electronic and electrical equipment related to human exposure restrictions for electromagnetic fields (0 Hz – 300 GHz).
• ICNIRP 494-522
• GMW 3097
• FMC-1278

Completing Your Automotive EMI EMC Standards Testing the Right Way

At HCT America Engineering, the team can help ensure that you complete your automotive EMC testing in an expedited and cost-efficient process. The first step is to ensure that you know your target market. This will help you determine the correct EMC test standards for automotive electronic components that are applicable to your device under test. HCT America can ensure proper testing of this functionality as well as all RF wireless connectivity standards.

Once you have done this, it’s essential to create a test plan which can be followed, and the HCT team can help you complete this step. A test plan review is a critical step. HCT America will review your test plan and ensure that it does match specific requirements for Automotive EMC standards.

Partnering with HCT America Engineering will ensure that you can provide ISO 7025 Accredited test reports to document compliance with the appropriate standards. The aim is always to deliver a comprehensive, fully transparent solution that achieves compliance with the applicable standards and assists in expediting market access.
