NBN ISO 24678-6:2021

This document provides requirements to govern the application of explicit algebraic formula sets to the
calculation of flashover-related phenomena.
This document is an implementation of the general requirements provided in ISO 16730-1 for the case
of fire dynamics calculations involving sets of explicit algebraic formulae.
This document is arranged in the form of a template, where specific information relevant to algebraic
flashover formulae are provided to satisfy the following types of general requirements:
a) description of physical phenomena addressed by the calculation method
b) documentation of the calculation procedure and its scientific basis
c) limitations of the calculation method
d) input parameters for the calculation method
e) domain of applicability of the calculation method.
Annex A contains a set of algebraic formulae each of which calculate the minimum heat release rate to
cause flashover in residential size enclosures.
