NOTE 2 It should be noted that the atmosphere surrounding the building can influence the ambience. NOTE 3 Annex A gives an example of classification of types of ambience. 3.3 building interior application

application in buildings for which the concerned construction products (i.e. components of the building fabric) are submitted to the influence of interior ambiences without significant exposure of any side of the product to the influence of exterior atmospheres NOTE 1 Building products include, for example: liner trays, ribbed profiles for roofing and walling, curved profiles, brake-pressed profiles, interior wall panels for partitions, ceiling panels, suspended frames (for suspended ceilings), factory foamed (or mineral wool) sandwich panels for cold rooms or rooms with controlled ambience, interior door frames, interior metal doors, interior metal windows. SIST EN 10169:2011+A1:2012

EN 10169:2010+A1:2012 (E) 8 NOTE 2 Some coil coated products can be used for interior applications having special performance requirements, e.g. lighting. In such cases, these particular requirements should also be considered in consultation with the manufacturer. NOTE 3 For interior building elements, it is important that the risk of corrosive attack on the reverse side of the element should also be considered. This can be especially important in double-skin assemblies (e.g. built up insulated cladding) where the reverse side of the interior element is not easily accessible for maintenance and/or in situations where the interior element is expected to provide long-term durability. NOTE 4 Besides the requirements written in this document, there can be other international or national requirements or regulations regarding fire, safety, food contact etc. that should be considered at the time of enquiry and order. 3.4 building exterior application

application in buildings for which the concerned products are submitted to the influence of exterior atmospheres

NOTE 1 Building products include, for example, ribbed profiles for roofing and walling, curved profiles, brake-pressed profiles, concealed fix roofing and walling, standing seam roofing, corrugated sheeting, cladding goods, sandwich panels for roofing and walling, roof tiles, accessories (flashings, trims), rainwater goods (gutters, down pipes), metal doors and garage doors. NOTE 2 For exterior building elements, it is important that the risk of corrosive attack on internal, i.e. reverse side surfaces, should also be considered. In particular, buildings with wet or chemically polluted internal environments can require a reverse side organic coating selected to provide enhanced corrosion protection. This can be especially important in double-skin assemblies (e.g. built-up insulated cladding) where the reverse side of the exterior element is not easily accessible for maintenance and/or in situations where the exterior element is expected to provide long-term durability. NOTE 3 Besides the requirements written in this document, other international or national requirements regarding reaction to fire , safety etc. can be agreed on at the time of enquiry and order. 3.5 coating flexibility ability of a coating to follow without !damaging" the deformation !deleted text" of the substrate !to which it is applied" !NOTE 1 The flexibility is determined during cold forming of the coated product by the T-bend test." !NOTE 2" Cold forming is the process where the main forming is done without heating the working piece.

3.6 coating material material comprising organic polymers, i.e. synthetic resin or plastics, to which pigments, additives and solvents (if required) have generally been added, suitable for coil coating NOTE These may be paints (in liquid or powder form) that when applied form an opaque film or plastic film providing protective, decorative and/or specific properties. 3.7 coating systems

3.10.2 film coating, permanent plastic film applied to the substrate to which generally an adhesive and, if appropriate, a priming coat has been applied beforehand

3.10.3 film coating, temporary strippable plastic film applied to the coated surface in order to afford a temporary protection against mechanical damage (see also 6.1.2.3) 3.10.4 intermediate coat coat between the priming coat and the top coat

Criteria of classification are related to their level of natural and artificial outdoor corrosion resistance. NOTE 2 These conditions determine the corrosivity category and include both meteorological and pollution parameters [EN ISO 12944-2]. NOTE 3 It should be recognized that in some local areas within a region, environmental conditions can apply which are not typical of the region as a whole, e.g. in a rural atmosphere close to a fossil fuel burning power generation plant, areas immediately down wind of the prevailing wind direction can be subjected to an environment closer to urban or even industrial atmospheres. Such special cases should be considered when organic coatings are chosen. 3.16 corrosivity category

C category which indicates the corrosivity of the environment taking into account both atmospheric conditions prevailing around a constituent element of a structure, and micro-environmental effects and shall be used for the selection of the appropriate product (related to EN ISO 12944-2) NOTE The relationship between corrosivity categories and types of atmospheres is given in Table 6. 3.17 gloss optical property of a surface, characterized by its ability to reflect light (related to EN 13523-2) NOTE For qualitative purposes, gloss ranges are often described by the terms "matt", "low gloss" or "semi-matt", "satin", "semi-gloss", "gloss" and "high gloss".
