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.

This document defines the fire resistance test and requirements for landing doors which are intended to provide a barrier to the spread of fire from the landing side and via the lift well in buildings for a period of time classified in this document. The fire resistance requirements are expressed in terms of integrity (E), insulation (EI) and radiation (EW). It is applicable to landing doors installed in the lift well openings at landings and used as means of access to lift car. It also specifies the method of testing and classification of fire resistance of landing doors. The test method is only valid for furnaces where the door is mounted in a vertical position. The test method specifies the measurement of integrity and if required the measurement of radiation and thermal insulation. This document refers to CO2 as means of tracing the propagation of fire. The document does not cover hazards due to emission of gases. This document is not applicable to landing doors which are installed before the date of its publication.
