scope:

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.
