ISO/TR 22899-2:2013 PDF

The test specified in ISO 22899-1 is designed to give an indication of how passive fire protection materials will perform in a jet fire. ISO/TR 22899-2:2013 provides: background information on the applicability and validation of the jet fire test; further details on testing pipe penetration seals; guidance on the interpretation of the tests results and on an optional classification system; guidance on the combination of results from hydrocarbon furnace tests and resistance to jet fire tests. ISO 22899-1 describes the thickness of fire protection material (sometimes referred to as passive fire protection; PFP) required to resist the application of a ?jet fire'. ISO/TR 22899-2:2013 provides information on the ?erosion factor' which is the additional thickness required above and beyond that required to satisfy the relevant criteria of ISO 834 (or other national or regional standards designed to evaluate the fire resistance with respect to a fully developed fire) for the element/construction under test.
