Over deze norm
NEN-EN 81-58 specifies the method of test for determining the fire resistance of lift landing doors which may be exposed to a fire from the landing side. The procedure 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. The procedure allows for the measurement of integrity and if required the measurement of radiation and thermal insulation. No requirements other than the verification that the specimen is operational are included for mechanical conditioning before the test as these are included in the relevant product standard.
