NT FIRE 032:1991 - Upholstered furniture: Burning behaviour – Full scale test.
Purpose
The standard is mostly used for upholstered furniture in public environments where the fire requirements are high.The standard is used to evaluate the fire progression for upholstered furniture under well ventilated conditions when subjected to a specified ignition source. Parameters like heat release rate, smoke production, mass loss and toxic gases can be measured.
NT FIRE 032 is solely a method for evaluating the fire behaviour of upholstered furniture, the standard does not contain any fire test criteria. Therefore, when testing according to NT FIRE 032, it is common to refer to test criteria in other test standards, for example the standard for nursing beds SS 876 00 10.
Method
The upholstered furniture is located on a weighing platform underneath a hood. The ignition source is a wooden crib, identical to "crib ignition source 7" in the British standard BS 5852. However, NT FIRE 032 also allows alternative ignition sources and normally another ignition source is used instead; a propane gas burner with a heat output of 30 kW. The ignition source is located on the seating area of the upholstered furniture and the fire is allowed to develop freely. During the test heat release rate, smoke production, mass loss, toxic gases etc. can be measured.
Deliveries
After testing, a test report in Swedish or English is delivered with the results.
