The Passive Fire Protection Handbook

STRUCTURAL STEEL
The Building Regulations require certain elements of structure to have fire resistance for a
specified minimum period of time. The amount of fire protection required to achieve this
depends on the following:
– Duration of fire resistance specified
– Type of protection used
– Perimeter of the steel section exposed to fire
– Shape and size of the steel section
To determine how these factors affect fire resistance, all Promat products and systems have
been tested at accredited laboratories to a variety of standards, e.g. BS 476: Part 21: 1987,
DIN 4102 and ASTM E119.
