After enquiries and votes carried out in accordance with the rules of this Association, this Standard has received the approval of the National Associations and the Official Services of the member countries of ASD, prior to its presenta

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2011, and conflicting national standards shall be withdrawn at the latest by October 2011. Attention is drawn to the possibilit

BS EN 2825:2011EN 2825:2011 (E) 4 1 Scope This European Standard defines a test method for determination of the smoke density due to pyrolitic decomposition of solid materials and composite materials of up to 25 mm in thickness under the influence of radia
18、nt heat only or with simultaneous flame application. The test results enable a comparison of the smoke production of different materials or material configurations under the conditions specified in this standard. NOTE 1 The smoke gas density is determined according to the specific environmental and
19、test conditions defined in EN 2824 and this standard. No studies have been made up to now to determine whether the results can be transferred to differing conditions, particularly to actual fire conditions. NOTE 2 The burning behaviour - and consequently the smoke density - of aerospace materials ar
20、e not only influenced by the type of material but also to a large extent by the configuration, the specific surface and mass, the combination with other materials, the means of joining as well as the processing technique. 2 Normative references The following referenced documents are indispensable fo

23、jected to decomposition by radiant heat only or with flame application. The smoke density is measured by means of the reduction of light transmission as smoke accumulates and expressed in terms of specific optical density which is derived from a geometric factor and the measured light obscuration. 4
