DBI has built a new Euroclass laboratory for reaction to fire testing of intermediate and large-scale products. Equipment therein includes new European tests for testing of reaction to fire and smoke release, including CEN tests for non-combustibility, calorific potential, fire growth rate, heat release and flame spread.
A room/corner test facility is available for testing in accordance with Nordtest, IMO and ISO test methods. The measurements can be supplemented with on-line gas analysis by means of a QGA gas analyser (mass spectrometer) for toxic gases.

standard testing to see the tests we can offer. In addition, we can offer a wide range of non-standardised (ad hoc) tests. We have, amongst other things, tested camouflage nets, measured the calorific value of nappies and the toxicity of various materials and we have also investigated the sooting tendency of candles.
Testing facilities:
Single Burning Item test
The Single Burning Item (SBI) test is the new European test method for testing building product's reaction to fire, prEN 13823. The SBI test is used for classification in Euroclasses A2, B, C and D and provides information about heat release, smoke production, flame spread and burning drops or particles.
Radiant Panel Test
The Radiant Panel test is the new European test method for testing af floor covering system´s fire properties, prEN ISO 9239-1. The method is used for classification in Euroclasses A2, B, C and D and provides information about flame spread and smoke production.
Room/corner testA full scale test method for testing product's reaction to fire. The Room/corner test provides information on, for instance, the development of heat and smoke. In addition, the smoke can be analysed for toxic gasses. The room/corner can be used when testing to the following standards: IMO Resolution MSC.40(64), ISO 9705, NT FIRE 025 and NT FIRE 036. When testing to ISO 9705, the room/corner is the larger scale reference scenario for the new European Single Burning Item test, together with existing Danish test methods for building product's reaction to fire.
GC/MS equipment
DBI has a state of the art HP 6890 gas chromatograph with HP5973 mass spectrometer as detector. Both manual injection and the use of a HP 7694 headspace sampler are possible. In a headspace sampler, a fluid or a solid specimen is placed in a small glass container, which is closed using a rubber membrane and then heated.
Subsequently, a small quantity of the gas phase above the specimen is transferred to the gas chromatograph for analysis.
The GC/MS is used for detecting flammable liquids in samples collected from the scene of a fire but it is also used as a supplement to the QGA analyses of toxic gasses.
QGA gas analyser
The QGA is an on-line mass spectrometer, used for measuring the composition of the smoke and gasses from tests made in for example room/corner, smoke density chamber (ISO 5659-2) and DIN-furnace (DIN 53436). CO2, SO2, NOx, HCN, HCl, HBr and HF are all traced. The IMO specification for the contents of toxic gasses is given in the International Fire Test Procedures Code, Annex 1, Part 2.
Fire Suppression
We also perform tests on automatic extinguishing and
total flooding systems. Both standard and ad hoc testing are performed. One of the purposes of testing the automatic fire prevention systems is to determine the exact placement of nozzles and their output, when protection of a specific area or room is required.
The total flooding facility at DBI fulfils IMO standards for testing fire-extinguishing equipment in engine rooms on ships. It is furnished with a large fire-resistant glass front, which makes it possible to follow visually the entire course of the test from outside the test room.
Automatic fire extinguishing and flooding systems are used in shipping spaces, archives, computer rooms, production plants and for point protection as a supplement to a sprinkler system. Our total flooding facility can use either inert gasses or water.
