3.1

affected party

party that is impacted by a fire safety design, including property owners and other property stakeholders, or authority having jurisdiction or in charge of public safety, health and welfare

3.2

deterministic analysis

risk analysis approach (3.10) in which the fire safety design is evaluated using a set of worst credible case scenarios

3.3

engineering judgement

process exercised by a professional or a team of professionals who is qualified by way of education, experience and recognized skills to complement, supplement, accept or reject elements of an engineering analysis

3.4

fire safety engineering

FSE

application of engineering methods based on scientific principles to the development or assessment of designs in the built environment through the analysis of specific fire scenarios or through the quantification of risk for a group of fire scenarios

3.5

fire safety strategy

specification of design functions used in achieving fire-safety objectives that forms the basis for the design

3.6

functional requirement

fr

statement of the means to achieve specified FSO, taking into account the features of a built environment

Note 1 to entry: Mandatory functional requirements are required, explicitly or implicitly, by national regulations or building codes; voluntary functional requirements are expressed by other affected parties.

3.7

mandatory objective

FSO, such as life safety and protection of the environment, which is required by national regulations or building codes

3.8

performance criterium

PC

threshold of performance that forms an agreed basis for assessing the safety of a built environment design

3.9

probabilistic analysis

risk analysis approach (3.10) in which the fire safety design is evaluated using the full range of representative scenarios

3.10

risk analysis approach

method for comparing estimated risk and tolerable risk using some form of risk measure, which includes qualitative analysis (3.18) , deterministic analysis (3.2) and probabilistic analysis (3.9)

3.11

safety factor

multiplicative adjustment applied to calculated values to compensate for uncertainty (3.14) in methods, calculations, input data and assumptions

3.12

safety margin

additive adjustment applied to calculated values to compensate for uncertainty (3.14) in methods, calculations, input data and assumptions

3.13

trial fire safety design

design chosen for the purpose of making a fire safety engineering (3.4) analysis and evaluation

3.14

uncertainty

quantification of the systematic and random error in data, variables, parameters or mathematical relationships, or of a failure to include a relevant element

3.15

validation

process of determining the degree to which a calculation method is an accurate representation of the real world from the perspective of the intended uses of the calculation method, such as confirming the correct assumptions and governing equations implemented in a model when applied to the entire class of problems addressed by the model

3.16

verification

process of determining that a calculation method implementation accurately represents the developer's conceptual description of the calculation method and the solution to the calculation method

Note 1 to entry: The fundamental strategy of verification of computational models is the identification and quantification of error in the computational model and its solution.

3.17

voluntary objective

FSO that is required by affected parties (3.1) beyond mandatory objectives (3.7)

3.18

qualitative analysis

risk analysis approach (3.10) in which areas of increased risk are identified
