    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Tanja Cernosa; [2020]
    Nyckelord :Fire behaviour; Intermediate-scale facade tests; cone calorimeter; stone wool; phenolic foam; WRB; Technology and Engineering;

    Sammanfattning : In the last few years, the implementation of well-ventilated façades in buildings increased due to their improved energy performance. However, their double-wall construction due to the limited airflow within an air cavity represents a significant fire risk, since the flames that spread into the air cavity can elongate up to ten times.

  2. 2. Fire Safety of Facades

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Bogdan-Grigore Branisteanu-Albulescu; [2019]
    Nyckelord :polystyrene; graphene; façade; pyrolysis; Technology and Engineering;

    Sammanfattning : Façade fires are a big concern due to past incidents and the large number of victims encountered. Vertical flame spread mechanism specific to this type of fires is a complex phenomenon with parameters that are often difficult to be coupled. LÄS MER

  3. 3. Determination of Thermal Conductivity of Wood Exposed to Fire based on Small Scale Laboratory Trials for Finite Element Calculations

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Nyckelord :Väderskyddsduk; konkalorimeter; EN ISO 11925-2; byggarbetsplat; brandsäkerhet; europaklass; röktäthet; brandspridning; antändlighet; textile membrane for weather protection; cone caloriemeter; construction site; fire safety; Euroclass; smoke production; fire spread; flammability; Technology and Engineering;

    Sammanfattning : The aim of this thesis is to study the flammability and fire spread for textile membranes for weather protection. This thesis includes literature studies to determine current standards and recommendations available. Main focus however have been on the European classification system EN 13501-1 and construction site safety. LÄS MER

  5. 5. Brandrisker vid lägre syrehalter – Experiment i konkalorimetern

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Erik Linnå; Viktor Wahlström; [2014]
    Nyckelord :CACC; carbon dioxide; carbon monoxide; cone calorimeter; controlled atmosphere; fire risk; heat release; HRR; hypoxic air; mass loss rate; oxygen; particle board; time to ignition; brandrisk; effekt; effektutveckling; koldioxid; kolmonoxid; konkalorimeter; LTH; massavbrinningshastighet; spånskiva; syrehalt; tid till antändning; Technology and Engineering;

    Sammanfattning : This report has been conducted to examine the advantages and disadvantages of using an open system for experiments in the cone calorimeter with a vitiated air enclosure at low oxygen levels. Eight different experimental set-ups were conducted in which two were designed according to ISO 5660, i.e. the cone calorimeter in its standard configuration. LÄS MER
