  1. 1. Beständigheten hos brandimpregnerat trä

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Filip Engström; Hannes Psajd; [2024]
    Nyckelord :Fire retardant treated wood; ISO 5660–1; Permanence; Euroclass; Cone Calorimeter; ConeTools; Infrared spectroscopy; Technology and Engineering;

    Sammanfattning : This report explores the properties of fire-retardant treated wood. This report has investigated the permanence for this material as well as seeing if the process of accelerated aging, which are used to determine the life span of the material, can be comparable to natural aging.

  3. 2. Time to ignition for wood covered with ZnO : A laboratory and theoretical study if ZnO can enhance time to ignition for wood exposed to radiation in the cone calorimeter

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Olina Öhrn; [2023]
    Nyckelord :ZnO; zinc oxide; cone calorimeter; wood; reaction-to-fire;

    Sammanfattning : In recent years, interest in sustainability and being environmentally friendly has increased. Wood is a durable and renewable building material, which is becoming more common in the constructions industry. In 2002, the government in Sweden adopted a national strategy to promote an increased use of wood in buildings. LÄS MER

  4. 3. Svällande brandstopp i fasadsystem - En experimentell studie

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Johan Bengtsson; Alex Åkesson; [2021]
    Nyckelord :Fasad; luftspalt; brandstopp; fuktmättnad; rainscreen cladding; Technology and Engineering;

    Sammanfattning : Since many new techniques and new materials have been introduced in the construction of facades there is a need to better understand the behavior when exposed to a fire. Recent facade fires involving rainshield claddings have displayed major consequences regarding the personal safety of the occupants and towards an economic loss. LÄS MER

  5. 4. Utvärdering av PIR-isolering med Konkalorimeter

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Gustav Hahlin; [2019]
    Nyckelord :PIR; cone calorimeter; ISO-5660; Technology and Engineering;

    Sammanfattning : In this study four different types of PIR materials have been tested to examine the possibility to use the cone calorimeter (ISO 5660) as a screening tool to evaluate the fire properties of the insulation. As such, manufacturers can be able to make a quick control of the insulation without having to spend resources on full scale testing. LÄS MER

  7. 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
