EN 15619:2008 (E) 4 Introduction The purpose of this European Standard is to specify the characteristics, the requirements and the test methods for coated fabrics intended for temporary structure and tents. Particular care has been taken not to come in conflict with the items that have already been treated in
EN 13782. This European Standard has been drawn up according to past experience and risk analysis. The content of this European Standard collects the different existing national regulations and refers to the different European test standards available for coated fabrics.
This European Standard also introduces a system of levels. It is not possible to divide coated fabric for tents into just a few performance levels, because of the enormous variety of conditions of use. This European Standard proposes different level of performance (A, B, C) for each characteristic – or T1, T2, T3, T4 for the fire behaviour. This allows to choose the appropriate level for each characteristic and so to compose a "product profile", adapted to each specific type of use. This means that for small tents exposed to low wind and snow loads but high exposition to sun light, a mechanical resistance level C may be required combined with a colour fastness level A. The level system should absolutely not be interpreted as if a coated fabric for tents needs to be rated "A" for all properties in order to obtain a "class" A. This European standard specifies requirements which are useful at design, calculation, manufacture, installation, maintenance, operation, examination and testing of coated fabric.

Coatings on one or both sides guarantee the integrity, contribute to the protection of the fabric against mechanical damage, atmospheric influence, and also against damage caused by animals, plant, and chemical agents. Coatings may be covered by a top coating providing additional protection of the surface against soiling and discoloration.

EN 15619:2008 (E) 7 5 Characteristics relating to coated fabrics 5.1 Mass per unit area The mass per unit area of the coated fabric shall be measured in accordance with EN ISO 2286-2. 5.2 Tensile mechanical behaviour Tensile strength shall be measured according to EN ISO 1421. Tensile properties measured by means of EN ISO 1421 monoaxial tensile test in warp and weft direction are most of the time sufficient for design. However, if more accurate data are required for design, complementary biaxial tests simulating real load conditions may be carried out on the membrane.
5.3 Tear strength In order to assess the risk of propagation of a tear due to lack of quality of the coated fabric or to an accident, the tear strength performances of a coated fabric shall be measured according to EN 1875-3 and declared by the manufacturer. 5.4 Coating adhesion The adhesion between the base fabric and the coating layer of the membrane material shall be assumed by coating adhesion tests according to Annex B. 5.5 Dimensional stability
During its life the tent membrane made up of coated fabric is submitted to many environmental loads (wind, snow, rain) and many mounting and dismantling of the structure. In order to limit any dimensional change of the membrane panels during the life of the tent, the fabric shall be dimensionally stable. The dimensional stability of the fabric shall be measured in both directions according to the test method described in C.1. For tents exposed to elevated temperatures during their use, an optional test is proposed in Annex C including a heat exposure (C.2) before mechanical loading. 5.6 Colour fastness to weathering and light The samples are exposed according to Annex A. Colour fastness is assessed by comparison with the grey scale and the specimens exposed for 2000 h to artificial ageing and the non-exposed specimens. The ageing procedure detailed in Annex A is based on EN ISO 4892-3 exposure mode 1 (UV, moisture cycle, and elevated temperature) that simulate the outdoor natural ageing.
5.7 Susceptibility to the development of microorganisms
In some climatic and environmental conditions, microorganisms may fix and develop on the surface of the coating. Their presence may damage the coating layer itself (discoloration, degradation of plastic coating) and may also hinder the use of the coated fabric membrane. The manufacturer of the coated fabric shall ensure that the coated fabric is treated with adapted treatment or sufficiently resistant to the action of microorganisms according to EN ISO 846. 5.8 Appearance Inspection of the appearance of membrane is important not only from an aesthetic point of view, but also from the aspect of examining for the presence of defects causing structural problems and of obstructions during usage. Appearance should be visually inspected on microscopic images taken under appropriate lighting at x SIST EN 15619:2009



EN 15619:2008 (E) 8 50 or x100 magnification. Microscopic images of two or more cross-sections and surfaces should be taken so that the cross-sectional and surface characteristics of the fabrics are checked.
The inspection items include: a) thickness of protective coating on the surface of yarns;
b) defects on yarns and their arrangement;
c) cracking of the coating and adherence of dirt, stains and foreign matter;
d) other defects which may cause obstruction in usage.
Inspection of those items shall be carried out according to sampling plans of a single lot of membrane material. Judgement criteria for the inspection items are determined in accordance with the usage and grade of membrane materials. 5.9 Reaction to fire 5.9.1 General In order to protect peoples against the risk of full development of fire, the coated fabrics used for tent or related structures shall have an appropriate reaction to fire behaviour. For this purpose, the coated fabrics shall be tested according to EN 14115. In addition, the test report shall mention for each specimen:
 the time of opening of the fabric (to be taken into account the hole shall be at least 1 cm2);
 the length and width of the hole at the end of the test The values (time of opening, length and width of the hole) declared on the test report shall be an average of the value measured for each sample. The coated fabrics used for tent covering, walls, textile decorations and related applications inside tents shall be classified in accordance with the following classification system.
Materials shall be classified in 4 categories (T1, T2, T3, or T4) or declared "Non classified". 5.9.2 Level T1 During the test, the duration of flaming shall not exceed 5 s after removal of the pilot flame; any propagation effect from ignition point shall not exceed 25 cm from the lower edge of the specimen. If there is any fall of droplets or particles which continue to burn after being in contact with the floor of the apparatus, the material is classified T4. If burning droplets or particles do not burn after being in contact with the floor, they are not taken into account.
5.9.3 Level T2 The material is classified T2 if the following conditions are fulfilled:
 the material is not classified T1;  the average value of the maximum length of the destroyed area from the lower edge of the test specimen is lower than 350 mm. SIST EN 15619:2009



EN 15619:2008 (E) 9 If there is any fall of droplets or particles which continue to burn after being in contact with the floor of the apparatus, the material is classified T4. If burning droplets or particles do not burn after being in contact with the floor, they are not taken into account.
Products, that open and do not allow any contact between the pilot flame, shall be subjected and pass the complementary test according to EN ISO 11925-2:2002, Annex A. 5.9.4 Level T3 The material is classified T3 if following conditions are fulfilled:
 the material is classified neither T1 nor T2;  the average value of the maximum length of the destroyed area from the lower edge of the test specimen is higher than 350 mm and lower than 600 mm;  the average value of the maximum width of the destroyed area, covering that part of the test specimen between 450 mm and 600 mm from its lower edge, is lower than 90 mm. If there is any fall of droplets or particles which continue to burn after being in contact with the floor of the apparatus, the material is classified T4. If burning droplets or particles do not burn after being in contact with the floor, they are not taken into account.
5.9.5 Level T4
A material is classified T4 when it meet the requirements of level T1, T2, or T3 but falls of droplets or particles which continue to burn after being in contact with the floor of the apparatus are observed during the test. 5.9.6 Non classified materials
If material doesn’t meet the requirements of T1, T2, T3 or T4 level, this material is declared “non classified” (N.C.). A material that has not been tested according to EN 14115 by an independent and accredited laboratory is also declared “non classified” (N.C.). 6 Requirements This standard proposes different levels of performance (level A, B, C) for each characteristic. This allows to choose the appropriate level for each characteristic and so to compose a "product profile", adapted to each specific type of use. This means that low mechanical resistance may be combined with e.g. high colour fastness. The level system should absolutely not be interpreted as if a coated fabric for tents needs to be rated "A" for all properties in order to obtain a "class" A.
To ensure safe and durable performance, each characteristic of the tent covering membranes made up of coated fabric shall comply with the value and class declared by the manufacturer of the coated fabric accordance with the requirements of Table 1, Table 2 and, if required, Table 3.
