ASIL

Automotive Safety Integrity Level (ASIL) is a risk classification scheme defined by the ISO 26262 – Functional Safety for Road Vehicles standard.

This classification helps defining the safety requirements necessary to be in line with the ISO 26262 standard.

There are four ASILs identified by the standard: ASIL A, ASIL B, ASIL C, ASIL D. ASIL D dictates the highest integrity requirements on the product and ASIL A the lowest.

ASIL D represents likely potential for severely life-threatening or fatal injury in the event of a malfunction and requires the highest level of assurance that the dependent safety goals are sufficient and have been achieved.
