    Textiles, Furniture & Accessories

    We carry out the following tests on textiles, furniture and accessories:

    • B2 test as per DIN 4102-1
      The purpose of testing as per DIN 4102-1: 1998-05, Section 6.2, is to classify building materials on the basis of their fire behaviour. Testing (see 6.2.5) replicates loading due to a small, defined flame (match flame). During this exposure the inflammability and flame propagation have to be limited within a certain specified period of time. Details will be found in DIN 4102-1: 1998-05, Section 1.2. The test is deemed to have been passed if, for none of the five specimens 

      a) for flame exposure to the edges (specimen dimensions = 90 mm wide x 190 mm long); as per section 6.2.5.2 and

      b) also for flame exposure to the surface (specimen dimensions = 90 mm wide x 230 mm long) as per 6.2.5.3 the tip of the flame reaches the measurement mark before the 20th second has elapsed.
    • B1 test as per DIN 4102-1
      Testing in the fire testing shaft is described in DIN 4102-16. The fire testing shaft itself is described in DIN 4102-15. Passing the B2 Test is the prerequisite for conducting the B1 Test.
      The purpose of testing as per DIN 4102-1: 1998-05, Section 6.1, is to classify building materials (with the exception of floor coverings) on the basis of their fire behaviour. Details will be found in DIN 4102-1: 1998-05, Section 1.2. Testing (see 6.1.3.1) models the burning of an object within a room (e.g. waste paper basket in the corner of a room). With this kind of exposure, the propagation of the flame may not extend significantly beyond the primary fire region; only a limited amount of heat may be released. The fire shaft test, normally conducted using test specimens drawn from four specimens 190 mm wide and 1000 mm in height, is deemed to have been passed if during and after the test:

      a) the mean value of the residual lengths (as per Section 9.1 of DIN 4120-16:1998-05) of each test specimen is at least 15 cm and no specimen exhibits a residual length of 0.

      b) the mean smoke temperature does not exceed 200°C in any test.
    • DIN EN ISO 6941, Textiles – Fire behaviour – Measurement of flame propagation for specimens in a vertical orientation
    • Testing the ignitability of upholstered furniture as per DIN EN 1021-1 (smouldering cigarette)
    • Testing the ignitability of upholstered furniture as per DIN EN 1021-2 (using a match or comparable gas flame)
    • Testing the ignitability of mattresses and upholstered bed boards (smouldering cigarette) as per EN 597-1
    • Testing the ignitability of mattresses and upholstered bed boards (using a match or comparable gas flame) as per EN 597-2
    • DIN EN 2824 and DIN EN 2826, Aviation and aerospace – Fire behaviour of non-metallic materials when exposed to radiant heat and flames – Determining smoke density and the smoke components for materials; testing devices, equipment and resources
