Matresses - Burning behaviour - Full scale test (NT TR 602)

NT TR 602

  • A new test method for testing of fire properties of mattresses is proposed. The method is intended to evaluate the full scale burning behaviour of a complete mattress or bed system when exposed to a flaming ignition source. Fire performance criteria, for mattresses used in public occupancies, are proposed.

Resthållfasthet hos brandskadad betong (NT TR 596)

NT TR 596

  • I projektet har självkompakterande betong med respektive utan fibrer samt en konventionell betong, K30 ingått. Av dessa göts provplattor som sedan exponerades för brand enligt ett standardförfarande. Ur plattorna och ur referensprover borrades kärnor för vidare provning. De metoder som tillämpats är tryck och spräckhållfasthet, ultraljud, BET, mikroskopi samt borrmotstånd och punktlastindex.

Fire-LCA guidelines (NT TR 583)

NT TR 583

  • Fire-LCA is an LCA method that incorporates fires as one possible end of life scenario. It was developed by SP and IVL in order to be able to assess lifecycle aspects of the fire performance of products. This report gives guidelines on how to perform a Fire-LCA study. They are written based on the experience made during the development and application of the Fire-LCA methodology to different case studies.

Interpretation of new test standards for fire resistance test (NT TR 555)

NT TR 555

  • The objective of the project has been to find a common Nordic approach on how the new EN test standards on testing of fire resistance of building products should be applied until the CE marking has been fully established.

Korrosjonspåvirkning fra brannimpregnert trevirke - En ringtest og ny prøvemetode (NT TR 546)

NT TR 546

  • En akselerert metode for å vurdere korrosjonspåvirkningen fra brannimpregnert tre på festemidler er testet ut ved å eksponere prøvene i et fuktig klima (RF = 90 %) ved 27 °C og sammenlikne med korrosjon i utendørs eksponering i ett år.

Modelling of the radiative feedback from the flames in cone calorimeter (NT TR 540)

NT TR 540

  • The ignition and combustion properties of building materials are often studied using the Cone Calorimeter (ISO5660:1993, NT Fire 048:1993), where the sample is heated by a temporally and spatially constant incident radiative heat flux. After ignition, however, the heat transfer characteristics are changed due to the flame radiation and convection.

Nordic Round Robin and Investigation on IMO Resolution A 653 (16) (NT TR 529)

NT TR 529

  • This Nordtest Project critically examines the deviations from the IMO resolution A.653 (16) method, which the participating laboratories either uses or has been using, that being deviations from: the equipment, the procedures or the interpretation of data. These deviations are in many cases a result on the imprecise and equivocal description of the method described in the IMO resolution A.653 (16) in FTP Code.

Improving heat fluxmeter calibration for fire testing laboratories (HFCAL) (NT TR 527)

NT TR 527

  • Tests of resistance to fire, representing fully developed fires, use more and more often heat flux gauges. In reaction to fire testing the initial stages of the fire are considered, ranging from smouldering cigarettes to small flames and "Single Burning Items". To characterise the thermal load to the test specimen, all national and international test methods need a direct measurement of the heat flux incident on the specimen.

Uncertainty in heat flux calibrations performed according to NT FIRE 050 (NT TR 494)

NT TR 494

  • The combined expanded uncertainty for calibrations according to NT FIRE 050 performed in the furnace at SP is calculated and presented. The result is presented in tables so that the parameters that contributes most to combined uncertainty is easily recognized.

Development of a test procedure for sandwich panels using ISO 9705 philosophy (NT TR 480)

NT TR 480

  • Assessment of the fire behaviour of sandwich panels often requires large scale testing. The fire behaviour of these panels is a combination of material characteristics such as the core material and mechanical behaviour of the panels such as joints, dilations etc.

Uncertainties in measuring heat and smoke release rates in the room or corner test and the SBI test (NT TR 477)

NT TR 477

  • When performing fire testing and classifying materials, Heat Release Rate (HRR) and Smoke Production Rate (SPR) are two of the most important quantities to determine. In this work, the individual sources of errors are defined for the HRR and the SPR calculations, with regard to the Room/Corner Test and the Single Burning Item (the SBI) test.

Physical interpretation of temperature data measured in the SBI fire test (NT TR 416)

NT TR 416

  • In the SBI fire test, there are temperature sensors in the exhaust duct allowing measurement of the temperature rise of the exhaust gases (T measurement). In principle these sensors provide means to monitor the production rate of thermal energy.
