This document specifies the fire resistance requirements for lift landing doors which can be exposed to a fire from the landing side. This document applies to all types of lift landing doors used as a means of access to lifts in buildings and which are intended to provide a fire barrier to the spread of fire via the lift well.
It also specifies the method of testing and classification of fire resistance of lift landing doors. The test method is only valid for furnaces where the door is mounted in a vertical position. The test method allows for the measurement of integrity and if required the measurement of radiation and thermal insulation.
This document covers the hazard of fire spreading to the lift well during a defined period of time. The fire resistance requirements are expressed in terms of integrity (E), insulation (EI) and radiation (EW).
This document do not cover other technical requirements in addition to fire resistance requirements. The other technical requirements are specified in relevant product standards referring to this document.
This document refers to CO2 as means of tracing the propagation of fire. The document does not cover hazards due to emission of gasses.
This document is not applicable to lift landing doors installed in lifts before the date of its publication.
