2 Test procedure

  2.1 Tests for bulkhead, wall and ceiling linings should be performed according to the standard ISO 9705, the room/corner test. This standard gives alternatives for choice of ignition source and sample mounting technique. For the purpose of testing products to be qualified as “fire-restricting materials", the following should apply:

  • .1 ignition source: Standard ignition source according to annex A of the standard ISO 9705, i.e. 100 kW heat output for 10 min and thereafter 300 kW heat output for another 10 min. Total testing time should be 20 min; and

  • .2 specimen mounting: Standard specimen configuration according to annex G of the standard ISO 9705, i.e. the product is mounted both on walls and ceiling of the test room. The product should be tested complying to end use conditions, including any surface finish materials or other surface treatments.

  2.2 Tests for materials used for furniture and components other than room linings should be performed according to the standard ISO 5660, the Cone Calorimeter Test. For the purpose of testing products to be qualified as "fire-restricting materials", the following test conditions should apply. Three test specimens should be prepared and tested in accordance with standard ISO 5660-1 (time to ignition and heat release) and the standard ISO 5660-2 (smoke production). The specimen should be representative of the end use conditions of the material, including any surface finishes. A sample edge frame should be used in all tests. Irradiance level should be set at 50 kW/m2 for all three tests. The test should be terminated when 20 min have elapsed since the start of exposure. Data should be collected for an additional 2 min after the end of a test to ensure that data are available for the entire test duration after time-shifting to account for delay times of part of the instrumentation.
