Fire reaction tests on doors
When we talk about fire resistanceor reaction to fireduring a fire?From the moment of ignition, which can hatch in a more or less long time, to the propagation of flames, we speak of reaction to fire. In this phase the behaviour of the materials, which "burn little", do not drip, smoke little, is decisive in order to prevent the fire from developing and spreading and to allow an exodus as orderly and long as possible. If we think for example about the fire reaction of wood, according to EN13501it is D S2 d0. This acronym means that exposed to fire burns (D is a class from A to F, in ascending order of class), smokes (S goes from 1 to 3, always in ascending order), and does not drip (d goes from 0 to 2). The exodus takes place in this phase, where it is crucial to choose the right strategies, such as materials with a good reaction to fire, smoke-proof doors to facilitate the exodus, orderly escape routes and fire-fighting equipment. Then (we are talking about 5 minutes after the spread of the flames, not two hours...) we arrive at the so-called "Flashover". It is generally defined as the transition to a fully developed fire in which all combustible materials in the compartment are involved in the fire mainly due to radiation from the products of combustion. From then on, laboratory tests simulate fire resistance, generally the ability to prevent fire from spreading from one compartment to another.
REACTION TO FIRE TESTS FOR BUILDING MATERIALSGenerally the fire reaction tests on building materials are carried out according to the following standards: EN ISO 1716:2010 Fire test reaction for products - Determination of gross heat of combustion (calorific value) EN ISO 9239-1:2010 Fire test reaction of floor coverings - Part 1: Determination of burning behaviour using a radiant heat source EN ISO 11925-2:2010 Fire test reaction - Flammability of products subjected to direct flame effects - Part 2: Single flame test. EN 13823:2010 Fire test reaction for construction products - Construction products excluding floors exposed to a single element thermal attack (SBI). UNI EN ISO 9239-1:2010 Fire performance testing of flooring - Part 1: Evaluation of fire performance using a radiant heat source. UNI EN ISO 1182:2010 Fire performance tests of products - Non-combustibility test Normally the reaction to fire classification is determined with an articulated set of several tests.
FIRE REACTION TESTS ON INTERIOR DOORSUntil some time ago, when they asked about the fire reaction of doors, we tended to say that doors can be FIRE RESISTANTand that they do a compartmentalisation job. FIRE REACTIONis something about cladding materials. However, we have been contradicted by standard EN14351-2(internal doors), which has specific provisions related to the reaction to fire of products and components with special tests. This is discussed in Article 4.5. The relevant components that can be tested are:
THE CHEMOLLI FIRE CONTRIBUTIONWhen it comes to testing, we provide our experience and our KNOW-HOW. Having always done this type of activity, as specialists, we offer you complete advice during all the laboratory experimentation phases, from design to documentation of results. THE METHOD Listening is the most important phase of our interaction: we want you to develop a product that is the sum of your identity and your needs. First of all, we'll try to understand your real needs, the channels and the markets you want to measure yourself on. Then we will show you how the testing and certification process takes place: we need to deal with you, to fully grasp your point of view. Then, we concert a proposal that respects - compatibly with the required performances - your product lines, your production lines and, as far as possible, the potential economies of scale by using products and methodologies already consolidated in your company. EMPATHY Beyond the opportunities, which we will show you, we will then advise you what we would do, in your shoes. We advise with our experience on what, how and where to test. In which laboratory should you test? In the one that best suits your needs! SPECIAL CONSIDERATIONS FOR FIRE REACTION ON DOORS It is clear that there are very different components and finishes in a range of products on the subject of reaction. It is important to try to understand the many variations that characterize the production. Normally we try to collect all this information and represent the range, so as to identify which are the "worst" solutions to test so that many others are then covered by the scope of the results indicated in the standard.
