網頁Section Factors are calculated by dividing the external fire-exposed perimeter of the steel section by its cross sectional area. Fire testing of structural steelwork fire insulation is designed to relate section factor to insulation thickness for a variety of failure temperatures and this requires a large variety of sections to be fire tested. 網頁The section factor is defined as the surface area of the member per unit length (A m) divided by the volume per unit length (V). It is measured in units of m -1 .This was previously calculated as heated perimeter divided by …
