Fire safety engineering - Requirements governing algebraic formulae - Part 1 : general requirements

This document provides requirements to govern the application of explicit algebraic formulae sets to the calculation of fire 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 formulae are provided to satisfy the following types of general requirements:

a) Requirements governing description of physical phenomena;

b) Requirements governing calculation process;

c) Requirements governing limitations;

d) Requirements governing input parameters;

e) Requirements governing domain of applicability.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
