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.
