EN 16724:2015 (E) 4 1 Scope This European Standard specifies instructions for mounting and fixing for reaction to fire testing for External Thermal Insulation Composite Systems (ETICS) and gives rules for the field of application of test results. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 13238, Reaction to fire tests for building products - Conditioning procedures and general rules for selection of substrates EN 13501-1:2007+A1:2009, Fire classification of construction products and building elements - Part 1: Classification using data from reaction to fire tests EN 13823, Reaction to fire tests for building products - Building products excluding floorings exposed to the thermal attack by a single burning item EN 15725, Extended application reports on the fire performance of construction products and building elements EN ISO 1182, Reaction to fire tests for products - Non-combustibility test (ISO 1182) EN ISO 1716, Reaction to fire tests for products - Determination of the gross heat of combustion (calorific value) (ISO 1716) EN ISO 9229, Thermal insulation - Vocabulary (ISO 9229) EN ISO 11925-2, Reaction to fire tests - Ignitability of products subjected to direct impingement of flame - Part 2: Single-flame source test (ISO 11925-2) 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN ISO 9229 and the following apply. 3.1 gross heat of combustion QPCS heat of combustion of a substance when the combustion is complete and any produced water is entirely condensed under specified conditions Note 1 to entry: The gross heat of combustion is expressed in mega joules per kilogram. 3.2 adhesive component used for bonding the thermal insulation product to the substrate SIST EN 16724:2016

EN 16724:2015 (E) 6 3.14 non-substantial components material that does not constitute a significant part of a non-homogeneous product. A layer with a mass/unit area < 1,0 kg/m2 and a thickness < 1,0 mm is considered to be a non-substantial component Note 1 to entry: Two or more non-substantial layers that are adjacent to each other (i.e. with no substantial component(s) in between the layers) are regarded as one non-substantial component when they collectively comply with the requirements for a layer being a non-substantial component. [SOURCE: EN 13501-1:2007+A1:2009, 3.1.6] 3.15 organic content total amount of organic substances as part of a component or a product related to the mass in cured and dried conditions Note 1 to entry: Will be declared by the system holder according to the formulation of the product in question and will be determined by calculation. It is given in percentage by mass in cured and dried condition. 3.16 worst case configuration of specified ETICS components for test purposes that leads to the most discriminating class or level of a certain characteristic which leads to results valid for a group of configurations with assumed equal or better performance Note 1 to entry: Characteristics can be e.g. impact resistance, reaction to fire, etc. 4 Principle The reaction to fire classification (Euro classes) shall be determined in accordance with EN 13501-1, respecting the test conditions of the ETICS laid down in this standard. In order to evaluate the reaction to fire all kits of the design ETIC system as well as the individual components shall be considered. Test results may be also valid for the assessment of the reaction to fire of further design ETICS. Rules are given below. NOTE 1 A European reference fire scenario has not been laid down for facades. In some Member States, the classification of ETICS according to EN 13501–1 might not be sufficient for the use on facades. An additional assessment of ETICS according to national provisions (e.g. on the basis of large scale tests) might be necessary to comply with Member State regulations, until the existing European classification system has been completed. NOTE 2 In some Member States the requirements might exist to demonstrate the behaviour of products with respect to continuous glowing combustion in the case of fire. Additional national assessments e.g. on the basis of national procedures to demonstrate this behaviour might be required until a European harmonized procedure will be available. 5 Instructions for mounting and fixing, field of application 5.1 General This clause gives instructions for mounting and fixing for reaction to fire testing of a kit and its single components. This clause includes the field of application of the test results of the kits as well as of its single components. SIST EN 16724:2016



EN 16724:2015 (E) 7 Base coats shall be grouped according to the binder type into inorganic (cement-calcium hydroxide, alkali silicate, etc.) and organic (silicon resin, synthetic resin, etc.) coats. Finishing coats shall be grouped in the same way. For each group of base coats and finishing coats the product with the highest organic content shall be tested in combination with the adhesive having the highest organic content. If there are only differences in the organic content but no difference in the organic component itself, the product with the highest organic content shall be tested. The test results are valid also for adhesives, base coats and finishing coats with equal or lower organic content. If adhesives, base coats or finishing coats include flame retardants, those components with the lowest amount of flame retardant shall be tested additionally. The key coat and the decorative coat may be neglected if the layer thickness of each coat is less than 200 µm and the organic content is less than 5 %. NOTE The layer thickness may be calculated by the coverage. Key coat and decorative coat shall be considered for testing unless it can be neglected according to the rules mentioned in the paragraph before. The key coat and the decorative coat with the highest PCS-value (according to EN ISO 1716) shall be used for preparing the specimens. 5.2 Testing according to EN ISO 1182 (Non-combustibility test) 5.2.1 General This test method is relevant for the classes A1 and A2. For classes A1 and A2 every substantial component (3.12) shall be tested. Mechanical fixing devices and ancillary materials which are not continuous but discrete components of an ETICS shall not be considered for testing and classification regarding non-combustibility. NOTE Base coats, finishing coats and adhesives in accordance with the provisions of EC decision 96/603/EC (amended by decisions 2000/605/EC and 2003/424/EC) are considered to satisfy the requirements for performance class A1 without the need for testing. 5.2.2 Base coat
