Fire testing according to NT FIRE 043
NT FIRE 043 – Large, free-hanging curtain and drapery textiles: Heat release, fire spread and smoke production – Full scale test.
Purpose
The test method simulates a fire in a large free-hanging vertical textile that can give off high heat release and cause fast fire spread. The method is applicable in cases where ignitability (materials difficult to ignite) is not enough to reach certain demands on fire properties.
During a fire in a high risk environment, a large textile is one of the components that constitute the greatest fire hazard because it can develop large amounts of heat and smoke and speed up the fire spread.
The test method NT FIRE 043 measures among other parameters the heat release and smoke production. The product can be classified according to the criteria in appendix F. Test data on heat and smoke production from the textile can also be used as input for fire modeling.
Method
The method evaluates vertically oriented textiles technical fire properties when it is exposed to a gas burner with an output effect of 100 kW. The following parameters are measured: developed heat release, smoke production, weight loss, flame spread (top of specimen) and maximum flame height from the floor.
Deliveries
A test report, in Swedish or English, is delivered with the test results after testing.
