Fire Resistance Classification RENO & TAPALUZ




 We are pleased to announce that both the Velvet RENO as the DiM OuT TAPALUZ have achieved the German B1 fire reaction classification according to DIN 4102 standard.


 So already obtained the classification of reaction to fire Spanish ( C -1 ) and the French (M -1 ) , is joined by the German ( B-1 ),


 Flammability testing is arguably one of the most important testing procedures within the textile industry because it has crucial safety implications in the event of a fire.


 It has been statistically shown that the major cause of fatalities in fire can be directly attributed to the accidental ignition of  textiles,


 Unfortunately, there is no single flammability standard for  vertical surface fabrics which has been adopted as the norm throughout the world and the plethora of different standards in force internationally reflects the different ways of approaching the whole flammability issue.




 In Germany, verticval surface fabrics are tested in accordance with DIN 4102 which has been established by the Deutsches Institut fŸr Bautechnik. 


 DIN 4102 Parte 1 - Kleinbrenner (B2)


 The fabric specimen is suspended vertically and a 20mm high flame is applied for 15 seconds to both the fabric surface and edge. 


Reference lines are marked on the specimen, which achieves B2 classification if the tip of the flame does not reach the reference marks within 20 seconds on any sample. 5 samples are tested with filter paper being placed below each to determine the production of flaming droplets. 


 DIN 4102 Parts 15/16 - Brandschacht (B1) 


 Referred to as the "Brandschacht test", this is the main test method in Germany which measures reaction to fire and is considered the highest flammability standard in the country for fabrics.


 The term Brandschacht, literally "fire shaft", refers to the testing apparatus itself which consists of a square-shaped vertical housing equipped with a gas burner. Four fabric samples are held vertically in a supporting frame and subjected to flames for 10 minutes. At the same time a constant, uniform flow of air is blown into the Brandschacht from below.


 In evaluating the test, smoke gas temperature and the mean residual length of the sample are taken into account (residual length is the part of the specimen which has escaped burning).


 In order to be classified as B1, the tested fabric must show:


 1. A mean residual length of not less than 150mm, with no specimen being burned away completely

 2. A mean smoke gas temperature of less than 200oC 


 Both VELVET RENO like DIM OUT  TAPALUZ of DABEDAN have obtained the German classification B1 according to DIN 4102, which makes them suitable and indicated for use as vertical textile decoration inside buildings Germano country.
