Automotive ECE R10 compliance
(1/1)

Hi,
I'm working on an automotive prototype project with local vehicle/trailer upgrade shop. The main function of the module would be driving some lights (totaling up to 10 A), supplied via vehicle battery (12 V) and module is connected to the vehicle harness. If this turns out to be a viable product it needs to be certified according to ECE R10 for E-marking ( https://ec.europa.eu/docsroom/documents/16513/attachments/1/translations/en/renditions/native ).
So, before I dive into the design, I figured I should see the regulatory requirements. There are many tests for emissions and immunity (conducted, transient, radiated, surges etc.) under R10. I couldn’t find any requirements/guidelines for part qualifications (AEC…) or quality grade (automotive etc.).
Is this area under different directive or are these specific requirements from buyers?
Is it mandatory to use automotive qualified parts for module to pass ECE R10 or is that up to designer? I am looking into using STM32F0x2 (temp range -40 to +85 °C or -40 to +105 °C, but not AEC qualified. Is that a dealbreaker from the start?
I am well aware that there should be some additional protection circuit with LDO for dealing with disturbances for good performance.
The high side drivers I am looking into are from STM VNQ series and Infineon smart power switches. Both automotive qualified but with different level of immunity to disturbances. This topic I must study a bit more.
How is that with passive components, is automotive grade mandatory?
In todays world with supply chain issues and long lead times, is it possible to change some elements (with similar characteristics, different suppliers etc.) without invalidating certification?
- Are there any additional tests required like exposing the module to mechanical vibrations, temperature (performance at 60C, 70C ambient for example)? ECE R10 is for electric but properties change under different conditions and ofc time.
- Any tests for module connectors (strain)?
- Is module housing/caase under any regulation (material type/properties)?
- Does a MCU software need to comply to any regulation (or the programmer)?
I suppose there can be many tests performed or requirements fulfilled if the buyer requests it but for now, I am focused on ECE R10 and proper performance in intended environment to get started.
As you can see, I have many questions manly just to gauge what does the undertaking of such project entails.
If someone could point me in the right direction I would be very grateful.
Thanks!
