scope:

1.1 The requirements in this standard govern the application of algebraic formula sets to the calculation of specific characteristics of vent flows. 1.2 This standard is an implementation of the general high-level requirements for the case of fire dynamics calculations involving sets of algebraic formulas. 1.3 This standard is arranged in the form of a template, where specific information relevant to algebraic vent flow formulas is 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. 1.4 Examples of sets of algebraic formulas meeting all the requirements of this standard will be provided in separate annexes to this standard for each different type of vent flow scenario. Currently, there are two informative annexes containing general information on vent flows and specific algebraic formulas for practical engineering calculations.
