EN 1101 for the measurement of ignitability (based on EN ISO 6940) and EN 1102 for the measurement of flame spread (based on EN ISO 6941). EN ISO 6941 measures the flame spread of vertically oriented specimens exposed to a defined small flame. This allows the flame spread properties of ignitable products to be determined. Nevertheless this test method is not suitable to assess products that do not ignite. The measurement of the length or area destroyed by the small flame is questionable as shown by round robin testing. There is a risk that products which pass the small flame test, can still be ignited with a larger ignition source. The equipment used in EN ISO 6941 has therefore been modified by adding a radiator, which radiates on the lower part of the specimen in order to boost locally and temporarily the ignition of the specimen. The combination of this radiation and the small flame application simulates the action from a larger flaming source. With 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. For this purpose, a European research project (CT 96-2057) was set up to establish a small scale test method for assessing the burning behaviour of curtains and drapes using a large ignition source. Reaction to fire parameters like smoke development, heat release and toxic components were not taken into account. The project involved eleven laboratories from nine European countries.
In order to select the relevant characteristics of burning behaviour in terms of classification and to assess the repeatability and reproducibility, 15 samples of commercially available fabrics representative for the main product groups on the market were tested with the large ignition source test method. Most of them had a flame retardant treatment or coating. The material selection included standard and fire retardant polyester, cotton, modacryl, wool, chlorofibre and glass fibre and represented different structures and fibre blends. The occurrence of flaming debris, the severance of marker threads and the time to sever marker threads (first and third threads) were selected as representative parameter to assess the burning behaviour of the samples. Other burning behaviour characteristics such as after-flame and after-glow times did not bring any extra relevant information and were discarded.
An inter-laboratory test was conducted in 1997 with ten laboratories, each testing 15 materials. Repeatability and reproducibility were assessed through statistical analysis. Consequently, some improvements were introduced in the method. Good agreement was also found with national test methods in use in various European countries or regions (France, Germany, Belgium, the Netherlands, Italy, Scandinavia and the United Kingdom).

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 exposure (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. SIST EN 13772:2011

Burning materials may produce smoke and toxic and corrosive 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. 6 Apparatus and materials This standard uses the equipment according to EN ISO 6941 modified as below. 6.1 Specimen holder: The specimen holder according to EN ISO 6941 has to be modified. To prevent the cotton cloth from falling down the specimen holder shall be equipped with an extra pin positioned centrally 20 mm from the bottom of the specimen on the holder (see below Figure 1).
