For example, an A(B) component is designed at the ASIL A level of requirements, but is made to fit into ASIL B designs (this subcomponent is colloquially described as "B-ready"). ISO 26262 contains multiple examples of allowed decomposition scenarios, for example ASIL B = A(B) + A(B), i.e. two redundant B-ready ASIL A subcomponents can be ...
ASIL classifications are used within ISO 26262 to express the level of risk reduction required to prevent a specific hazard, with ASIL D representing the highest hazard level and ASIL A the lowest. The ASIL assessed for a given hazard is then assigned to the safety goal set to address that hazard and is then inherited by the safety requirements ...
The tolerable level of these risks is specified as a safety requirement in the form of a target 'probability of a dangerous failure' in a given period of time, stated as a discrete SIL. Certification schemes, such as the CASS Scheme (Conformity Assessment of Safety-related Systems) are used to establish whether a device meets a particular SIL ...
It is also highly recommended for SIL 4 in part 3 Annex B of the basic safety publication [2] and ASIL D in part 6 of automotive standard ISO 26262. [3] Additionally, NASA requires 100% MC/DC coverage for any safety critical software component in Section 3.7.4 of NPR 7150.2D. [4]

ASIL accuracy describes the maximum possible deviation of a measurement in a system in which a single point fault occurred before some diagnostic detects this fault. This concept applies to automotive systems designed under the ISO-26262 methodology for automotive functional safety, which defines Automotive Safety Integrity Levels (ASILs) to classify risks.
