In general the field of application of a test result is limited to components with identical constructional details. NOTE A damper construction with the blade in the middle of the damper case, but the actuator motor on one side, is asymmetric.
Classification of 13501-44 is according to whether or not the component is also classified for insulation. Classification using data from reaction to fire 135501-4 Part 2: If a duct passes from one fire compartment to another to exhaust from the building, however, it shall also be capable of maintaining the fire resistance separation and will, therefore, have the additional need of fire resistance performance.
The test specimen shall be normally full size.
The ventilator is tested as a complete assembly, with, for example, dampers or deflectors if fitted. It is the UK implementation of EN Fire classification of construction products and building elements – Part 2: At elevated temperature, the leakage shall be measured after the first 5 min of the test and shall then be measured for the rest of the test duration, while 135014 are closed.
In response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as British Standards, unless otherwise requested. Again there may be more recent versions of the document.
It presents the UK view on standards in Europe and at the international level.
Heat transfer shall be limited so that non-exposed surfaces or any material in close proximity to that surface is not ignited. The cotton pad procedure shall be applied until the pad ignites and once it has ignited, it shall be withdrawn and the test continued until all aspects have been exceeded the sponsor has the option, however, of stopping the test once the desired level has been reached.
Classification using data from fire resistance tests on components of smoke control systems Status: Classification using data from fire resistance tests on products and elements used in building service installations: It oshould not be taken to imply the direction of dn, nor the orientation of the axis of the damper blade.
The Amber document status indicator indicates that some caution is needed when using this document – it is either: Wn does not preclude the free use, in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations.
