Determination of the resistance to jet fires of passive fire protection materials — Part 1: General requirements
This document describes a method of determining the resistance to jet fires of passive fire protection materials and systems. It gives an indication of how passive fire protection materials behave in a jet fire and provides performance data under the specified conditions.
It does not include an assessment of other properties of the passive fire protection material such as weathering, ageing, shock resistance, impact or explosion resistance, or smoke production.
Complete I-beams and columns cannot be tested to this document due to disruption of the characteristics of the jet.
