ASIL Levels for Automotive Electronics from China
1 resources tagged with "Asil"
ASIL (Automotive Safety Integrity Level) is the ISO 26262 risk classification — A through D — that determines how much functional-safety rigor an automotive electronic component requires, with ASIL D being the strictest (think braking and steering). It's derived from a HARA (Hazard Analysis and Risk Assessment) and backed by hardware metrics like PMHF and SPFM. When evaluating Chinese suppliers, the most common gap is a factory that claims 'ISO 26262 compliant' but cannot produce the ASIL-rated safety case or the supporting metric calculations.
In practice, ASIL is not a certificate a factory holds — it's a property of a specific part's safety design, proven by documentation. We ask suppliers for the safety manual, the assigned ASIL level per requirement, and the PMHF/SPFM figures; a vague compliance claim with no HARA behind it is the warning sign.

FAQ
Can a Chinese supplier really deliver ASIL D parts?
Some can, but the bar is high — you need a documented safety case, ASIL decomposition, and validated PMHF/SPFM metrics, not just a claim. Verify the safety manual and confirm the assessment was done by a competent body.
What's the difference between ASIL B and ASIL D in sourcing terms?
Higher ASIL means stricter hardware fault metrics, more redundancy, and far more documentation and testing cost. ASIL D parts can carry significantly longer qualification timelines and higher per-unit price than ASIL A/B equivalents.
