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 MATERIALS
Generally 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 DOORS
Until 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:
  • profiles (leaf - if uprights/beams - and frame);
  • internal material (glass or panel inserted if mullion/beam doors) or sash;
  • gasket or sealant between panel and profiles (if used if mullion/beam sash);
  • organic coating / top layers if they are not part of the profiles or panel.
Test methods are discussed in Annex F (normative) and in particular are used: UNI EN ISO 11925-2:2010: Reaction to fire tests - Ignition performance of products subjected to direct flame attack - Part 2: Single flame test On the profiles as indicated above, the samples must have a length of 250 mm, maximum depth 60 mm, without seals; On the internal material or on the door, with samples of 250x90 mm, maximum depth 60 mm. On the seal or component material or on the finished element, always with a length of 250 mm. UNI EN 13238:2010: Fire performance tests of construction products - Packaging procedures and general rules for the choice of substrates For wood or metal profiles, a representative coating on a plate. or for all other profiles, a representative coating on a plate of the same material as the profile (minimum wall thickness of the visible surface), with a length of 250 mm. The maximum depth of the sample is 60 mm. The test must be carried out with the surface flame only.
UNI EN 13823:2014:Tests for reaction to fire of construction products - Construction products excluding floors exposed to a thermal attack produced by a single burning object
Profile
Panel or leaf with maximum depth of 200 mm.
Organic coating / top layers
In this case the typical 1000x500mm SBI type corner, 1500mm high, with the flame in the corner.
Full door test
In this case the typical SBI 1000x500mm corner, 1500 mm high, with the flame in the corner, with a small door of 1000x1500 mm on the long side without handles or cylinders.
UNI EN ISO 1182:2010:Fire resistance tests of products - Non-combustibility test
This test is carried out on materials that are substantial parts of the products. In particular, a cylinder of material with a diameter of 45 mm and a height of 50 mm is made. ISO 1716:2018: Prove di reazione al fuoco per i prodotti -- Determinazione del calore lordo di combustione (potere calorifico) For solid components a sample of 50g and for liquid products a sample of 10g dry. FIELD OF APPLICATION OF THE RESULTS The product standard EN14351-2 also provides a direct field of application, which gives a whole range of variants:
  • that tests on wood with low densities are valid for those with higher densities;
  • that materials classified A1 do not require testing;
  • that the influence of the seals is considered negligible and is not relevant (obviously, apart from those between the filling panel and leaf profiles if uprights/beams);
  • that for organic finishes there are variant possibilities.
All these provisions are included in EN14351-2, a standard that is also published by UNI but has not been published in the European Official Journal (OJEU), so it is not known if and when it will be harmonised and therefore mandatory.
THE CHEMOLLI FIRE CONTRIBUTION
When 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.
