Scope

The tests specified in ISO 22899 1 and ISO 22899 3 are designed to give an indication of how passive fire protection materials and systems will perform in a jet fire.
This part of ISO 22899 provides:
— guidance on the selection of applicable method of test;
— guidance on the combination of results from hydrocarbon tests and resistance to jet fire tests.
ISO 22899 1 and ISO 22899-3 tests report the thickness of fire protection material or system (sometimes referred to as passive fire protection; PFP) required to resist the application of a ‘jet fire’. This part of ISO 22899 provides information on selection of the applicable test method and how to combine jet fire test results with other hydrocarbon fire test results.
