PD 7974-1:2019

This standard PD 7974-1:2019 Application of fire safety engineering principles to the design of buildings is classified in these ICS categories:

• 91.040.01 Buildings in general
• 13.220.20 Fire protection

This Published Document provides guidance on evaluating fire growth and/or size within the enclosure of fire origin, as well as enclosures to which the fire has subsequently spread.

The characteristics and products of the design fire for any particular scenario are influenced by a number of factors, including building design, environmental influences, potential ignition sources and location, types of combustible materials, distribution and arrangement of combustible materials, ventilation conditions and other events occurring during the fire.

The determination of the characteristics and products of the design fire from ignition through to decay is used by other sub-systems.
