Does the edge box automotive-grade EMC have to meet the ISO11452 standard?

If edge computing boxes are used in road vehicles, in addition to ISO7637 power line transients, they must also meet the ISO11452 series of vehicle component radiated immunity tests. ISO11452-2 uses the ALSE method (80-8000MHz, 100V/m), ISO11452-4 uses the high current injection BCI method (1-400MHz, 100mA), and ISO11452-5 uses the stripline method. Edge boxes are typically used as electronic subassemblies and need to pass BCI testing (1-400MHz, 100mA interference level). One solution is to use automotive-grade common-mode filters (CMLA4532A-510T) for all interfaces. The CMLA automotive-grade common-mode inductor is 4532, measuring 4.5×3.2mm. The 510T inductor has a capacity of 51μH and meets AEC-Q200 standards. Option 2 uses an SM8K33CA TVS at the power port, conforming to AEC-Q101 standards. Option 3 employs a multi-layer PCB layout with a complete ground plane to enhance immunity; therefore, automotive-grade EMC must comply with ISO 11452, which is not merely a recommended standard.
