ISO 16734:2006 govern the application of explicit algebraic equation sets to the calculation of specific characteristics of fire plumes.ISO 16734:2006 is an implementation of the general requirements provided in ISO/TR 13387-3 for the case of fire dynamics calculations involving sets of explicit algebraic equations.ISO 16734:2006 is arranged in the form of a template, where specific information relevant to algebraic fire plume equations is provided to satisfy the following types of general requirements:description of physical phenomena addressed by the calculation method;documentation of the calculation procedure and its scientific basis;limitations of the calculation method;input parameters for the calculation method;domain of applicability of the calculation method.Examples of sets of algebraic equations meeting all the requirements of ISO 16734:2006 are be provided for each different type of fire plume, including those for quasi-steady state, axisymmetric fire plumes.
