21、d EN ISO 6941 measures the flame spread of vertically oriented specimens ignited with a defined small flame. There is however a risk that products not ignitable with a small flame can be ignited with a more severe ignition source. The equipment used in EN ISO 6941 has therefore been modified with a
22、radiator, which radiates on the lower part of the specimen. The combination of this radiation and the small flame application simulates the action from a larger flaming source, e.g. a burning waste paper basket. This European Standard evaluates flame spread using this more severe ignition source. Wi
23、th this combined ignition source some materials, not ignitable with the small flame, may ignite. Some of these will self extinguish, when the action from the ignition source has ceased, while others will self propagate.

24、Uncontrolled Copy, (c) BSI EN 13772:2003 (E) 5 1 Scope This European Standard specifies a method for the measurement of flame spread of vertically oriented textile fabrics intended for curtains and drapes in the form of single or multi-component (coated, quilted, multilayered, sandwich construction
25、and similar combinations) fabrics using a large ignition source. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed he
26、reafter. For dated reference, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN 367:1992

28、2000) EN ISO 6941, Textile fabrics - Burning behaviour - Measurement of flame spread properties of vertically oriented specimens (ISO 6941:1984, including Amendment 1:1992) 3 Term and definition For the purposes of this European Standard, the following term and definition applies: 3.1 flaming debris
29、 material separating from the specimen during the test procedure, falling below the initial edge of the specimen and igniting a filter paper 4 Principle A heat flux of a defined energy is applied to a specified area of the lower part of the backside of the vertical specimen. After a period of exposu
30、re (30 s), the small flame defined in EN ISO 6941 is applied for 10 s to a small piece of cotton fabric fixed around the bottom edge of the specimen. The possible flame spread is measured through the severance of marker threads. 5 Health and safety of test operator Burning materials may produce smok
31、e and toxic gases which can affect the health of operators. Between tests the atmosphere of the testing location, which should be of adequate dimensions to avoid endangering the health of operators, should be cleared of smoke and fumes by an extractor fan or other means of ventilation.

The ap
37、proximate position is given in Figure 3. The shield shall be at least as wide as the specimen and made in a non-combustible material. It is sufficient if the lowest 200 mm of the specimen is shielded. NOTEThe non combustible material could be for instance metal or mineral silicate. 6.7 Marker thread
38、s The marker threads shall be of pure cotton with a linear density of (455) tex. Only the first and the third marker threads as specified in EN ISO 6941 are used. The position of the threads is given in Figure 2b. The threads shall be under a tension at least equal to that produced by a weight of 50
39、 g: 1 g. A possible arrangement for this is given in the same Figure 2b and 3. 6.8 Gas Commercial propane gas shall be used. 6.9 Cotton cloth Bleached fabric, plain weave, weight (16020) g/m. The material shall be washed one time before use according to EN ISO 6330, programme 2A, drying procedure A,

Mount the copper disc calorimeter centrally in front of radia
45、tor at the position of the specimen. Put the shield in position and put the radiator on via the transformer. Let at least 20 minutes elapse. Move the shield aside and let the temperature increase to at least 100 C. Measure the time needed for a temperature rise from 40 C to 100 C. The average temper
46、ature rise of the calorimeter between 40 C and 100 C shall be (3,0 0,1) C/s. If the temperature rise does not fall within the prescribed limits the voltage should be adjusted to a value which fulfils the requirement. The calibration shall be carried out at least once a year or more often if it is ne
47、cessary to keep the calorimeter temperature rise within the prescribed limits. NOTEThe calibration can alternatively be carried out separately without using the test rig, but the relative positions of the radiator and calorimeter should be maintained. 8 Sample and test specimen 8.1 Sample The test s
48、ample shall be taken so as to be representative of the materials as used in complete curtains and drapes. 8.2 Cleansing The sample shall be submitted to one cycle of the cleansing procedure given in the care label. If no cleansing procedure is prescribed, the material shall be submitted to one cycle
49、 of one of the following standard cleansing procedure as appropriates to the fabric: wash procedure, according to method 6A (403)C of EN ISO 6330 and flat dried in a accordance with method C of EN ISO 6330; dry cleansing procedure according to EN ISO 3175. If the fabric is not intended to be cleansed, it shall be tested as received. NOTEThis cleansing is not intended as a durability test for flame retardant treatment but only to remove non durable finishes
