BS ISO 26262-1:2011 pdf download.Road vehicles—Functional safety Part 1: Vocabulary.
architecture
representation of the structure of the item (1.69) or functions or systems (1.129) or elements (1.32) that allows identification of building blocks, their boundaries and interfaces, and includes the allocation (1.1) of functions to hardware and software elements
assessment
examination of a characteristic of an item (1.69) or element (1.32)
NOTE A level of independence (1.61) of the party or parties performing the assessment is associated with each assessment.
audit
examination of an implemented process
Automotive Safety Integrity Level
ASIL
one of four levels to specify the item’s (1.69) or element’s (1.32) necessary requirements of ISO 26262 and safety measures (1.110) to apply fo avoiding an unreasonable residual risk (1.97), with 0 representing the most stringent and A the least stringent level
ASIL decomposition
apportioning of safety requirements redundantly to sufficiently independent elements (1.32), with the objective of reducing the ASIL (1.6) of the redundant safety requirements that are allocated to the corresponding elements
availability
capability of a product to be in a state to execute the function required under given conditions, at a certain time or in a given period, supposing the required external resources are available
baseline
version of a set of one or more work products, items (1.69) or elements (1.32) that is under configuration management and used as a basis for further development through the change management process
NOTE See ISO 26262-8:2011. Clause 8.
branch coverage
percentage of branches of the control flow that have been executed
NOTE 1 100 % branch coverage implies 100 % statement coverage (1.127).
NOTE 2 An if-statement always has two branches - condition true and condition false - independent of the existence of an else-clause.
