3.2
functional safety
part of the overall safety (3.1) relating to the EUC (Equipment Under Control) and the EUC control system that depends on the correct functioning of the E/E/PE (Electrical/Electronic/Programmable Electronic) safety-related systems and other risk reduction measures
[SOURCE: IEC 61508-4, ed. 2.0 (2010), 3.1.12]

3.3

3.4
risk
organizational risk
effect of uncertainty on objectives
Note 1 to entry: An effect is a deviation from the expected. It can be positive, negative or both and can address, create or result in opportunities and threats.
Note 2 to entry: Objectives can have different aspects and categories and can be applied at different levels.
Note 3 to entry: Risk is usually expressed in terms of risk sources, potential events, their consequences and their likelihood.
Note 4 to entry: This is the core definition of risk. As risks are specifically focused on harm (3.5) a discipline specific definition of risk (3.3) is used in this document in addition to the core risk definition.
