3 Terms and definitions For the purposes of this document, the following terms and definitions apply: 3.1 stretched ceilings ceiling coverings comprising a continuous area obtained from one width or assembled widths kept under tension at its edges by a fastening system permitting dismantling and re-assembly These widths may be single or multi-layered sheets, coated fabrics or fabrics made up of coated yarn or monofilaments. Stretched ceilings may be perforated or not 3.2 product family total range of products within specific variability limits (defined by the manufacturer or a technical specification) of the product parameters and, if appropriate, of the final use parameters for which the specified safety characteristics do not change (do not deteriorate) This means that the test results obtained for one product in the family remain valid for all the products in the family 3.3 edge profile element fixed at the periphery of the ceiling to keep the ceiling stretched 3.4 anchoring device element connecting the stretched ceiling to the edge profile 4 Requirements relating to sheets and coated fabrics or fabrics made up of coated yarn or monofilaments 4.1 Essential requirements 4.1.1 Reaction to fire 4.1.1.1 Preparation and conditioning of test pieces The test pieces shall be conditioned prior to the test in accordance with EN 13238. 4.1.1.2 Ignitability test The ignitability test shall be carried out in accordance with EN ISO 11925-2. The flame shall be applied to the surface of the test piece fixed on the test piece holder by means of small pins incorporated in the surface of the U-shaped frame

wing and 1 300 mm × 1 800 mm to make the large wing. Stretch the sheet in the transverse direction across a calcium silicate panel with a tensile force of 30 daN/m determined in accordance with EN ISO 527-3.
There shall be an air gap of 40 mm between the stretched ceiling and the substrate when assembling the ceiling. This air gap is obtained by means of a calcium silicate frame of desired thickness fixed to the perimeter of the substrate of the small and the large wing. The final configuration may be obtained by pinching the stretched ceiling at the back of the substrate by means of an aluminium track and a PVC ring. Adequate tension shall be applied to obtain a satisfactory degree of flatness and no creasing over the whole of the exposed surface (see Figure A.1 in Annex A). b) In the case of coated fabrics or those made of coated yarn or monofilaments, take a 1 500 mm × 1 500 mm test piece. Fix the test piece to a metallic frame (see Figures A.2, A.3 and A.4 in Annex A). This frame comprises an assembly of stainless steel tubes of rectangular cross-section forming two perpendicular wings, one small and one large. Attach the test piece to the peripheral members of the frame by means of the steel pins.
Prior to the test, the test piece shall be adequately stretched and flat so that no more that 30 % of the total exposed surface shrinks by more than 10 mm from the coplanar vertical plane at the back of the U-profile Then place the frame against the U-profile on the test piece holder trolley. To be representative of the final use, conduct the test with a ventilated space 80 mm wide at the back of the test piece in accordance with EN 13823. Attach two calcium silicate walls made up of one small wing of (580 ± 5) mm × (1 500 ± 5) mm and one large wing of (1 080 ± 5) mm × (1 500 ± 5) mm vertically 80 mm from the test piece. The sides furthest away from the angle and the spaces behind each wing shall be left open. 4.1.1.4 Requirements If the manufacturer wishes to make a declaration of the reaction to fire performance (i.e. if the stretched ceiling is subject to regulations), the stretched ceilings shall be subjected to the test and be classified in accordance with the requirements of EN 13501-1 and the resulting class shall be declared. If it is decided not to declare a reaction to fire performance, i.e. to place a product family on the market as a class F product, no test is required for this product family. 4.1.2 Release of other dangerous substances 4.1.2.1 Heavy metals and other elements 4.1.2.1.1 Requirements The migration of heavy metals and other elements, expressed in mg/kg of stretched ceiling, shall not exceed the values given in Table 1 (after correction as specified in 4.1.2.1.2) when measured in accordance with test A in EN 12149.

Determination of the mass per unit area and thickness of the sheets B.1 Determination of the mass per unit area B.1.1 Apparatus Balance accurate to 0,005 g. B.1.2 Test pieces The test pieces shall be circular or rectangular with an area of 100 cm2 ± 0,5 cm2. Take at least three test pieces so that: d) one of them is centred on the longitudinal axis of the sheet, preferably 1 m
from the end of the roll; e) the other test pieces are cut symmetrically relative to this axis on the same transverse line, the end test pieces being situated close to the edges of the sheet but at least 50 cm from them, if possible; f) if the sheet is not wide enough to have the three test pieces aligned on the same transverse line, these other two test pieces may be moved in the longitudinal direction, but in such a way as to be located on the two symmetrical longitudinal axes relative to the median axis of the sheet. B.1.3 Conditioning Condition the test pieces at a temperature of 23 °C ± 2 °C for a minimum period of 3 h. B.1.4 Procedure Determine the mass of each test piece by means of balance B.1.1. B.1.5 Calculation and expression of results Calculate the mass per unit area, M, expressed in grams per square metre, for each test piece as follows: smM00010×= where m is the mass of a test piece, expressed in grams ; s is the area of the same test piece, expressed in square centimetres. Express the result as the mean of the values obtained for each test piece.

Determination of dimensional stability after exposure to moisture C.1 Scope The aim of the method described in this annex is to verify the suitability for use of the stretched ceiling in humid atmospheres, possibly charged with chlorine, such as those met in swimming baths for example. C.2 Principle A test piece of the stretched ceiling is subjected to the continuous action of water vapour possibly charged with chlorine. C.3 Apparatus and reagents C.3.1 Enclosure (see Figure C.1) The enclosure is a rectangular parallelepiped of 1 m × 0,5 m × 1 m. The bottom of the enclosure comprises a stainless steel tray 0,2 m high in which a resistor is immersed that is controlled by a regulator to maintain a temperature of 30 °C ± 2 °C. The top is removable to be able to load the test pieces. A fan is installed in the middle of one of the large vertical walls to ensure circulation of the vapours. The walls are fitted with hooks or holding devices to which the test pieces may be attached. The test pieces may be fitted flat or at an angle of 5° or 45°. C.3.2 Test solution Fill the bottom tray with a known volume of water and add (for the chlorinated solution test) the required quantity of commercially available chlorine tablets to obtain a concentration equal to 10 times the concentration normally used in public places. For the chlorinated solution test, it is necessary to verify that the concentration of the prepared test solution is exactly 10 times the concentration normally used in public places.
For that, take a sample of the chlorinated solution, dilute it in a ratio of 1 to 10 and assess its pH.
The pH shall be close to that of the chlorinated water used in public places.
Then, if necessary, adjust the concentration of the test solution. In order to allow good dissolution, the solution shall be prepared at least 8 hours before introducing the test pieces.
