Annex C informative Configuration factor
1 The configuration factor fy is defined in 1.3 1 P. It measures the fraction of the total radiative heat leaving a given radiating surface which arrives at a given receiving surface. Its value depends on the size of the radiating surface, on the distance from the radiating surface to the receiving surface and on their relative orientation. 2 In this Annex all radiating surfaces are assumed to be rectangular in shape. They comprise the windows and other openings in fire compartment walls and...

Foreword
The Structural Eurocodes comprise a group of standards for the structural and geotechnical design of buildings and civil engineering works. They are intended to serve as reference documents for the following purposes a As a means to prove compliance of building and civil engineering works with the essential requirements of the Construction Products Directive CPD . b As a framework for drawing up harmonised technical specifications for construction products. They cover execution and control only...
