3 Terms and definitions For the purposes of this document, the following terms and definitions in addition to the those in EN 10020:2000, EN 10021:1993, EN 10079:1992, EN 10169-1:2003, EN 10204:2004, EN ISO 8044 and EN ISO 12944-2:1998 apply. 3.1 Building exterior applications
all applications 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, factory foamed 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 or open-sided buildings and canopies the reverse side of which is exposed to sea salt aerosols 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 fire resistance, safety etc. can be agreed on at the time of enquiry and order. 3.2 Performance test test, the result of which should be related to the effective behaviour of the product on site 3.3 Local environment
atmospheric conditions prevailing around a constituent element of a structure [EN ISO 12944-2]. NOTE 1 These conditions determine the corrosivity category and include both meteorological and pollution parameters [EN ISO 12944-2]. NOTE 2 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. 3.4 Corrosivity category category which indicates the corrosivity of the environment taking into account both local and micro-environmental effects and shall be used for the selection of the appropriate product



EN 10169-2:2006 (E) 6 NOTE The relationship between corrosivity categories and types of atmospheres is given in Table 1. 3.5 Coating flexibility ability of a coating to follow without damage the deformation during cold forming of the substrate evaluated by the T-bend test 3.6 Corrosion resistance category category of product which presents a certain level of corrosion resistance, the choice of which depends on the corrosivity category, the period of resistance and the accessibility 3.7 UV resistance category category of coating which presents a certain level of resistance to degradation by UV radiation 3.8 Accessibility ease of access to the steel components for the purpose of inspection and maintenance without any work over and above that concerned with routine inspection 3.9 Saturated colour colour with Chroma C* > 40 NOTE Chroma C* is defined by CIE 15.3:2004. 4 Designation 4.1

EN 10169-2:2006 (E) 8 6 Requirements 6.1 General
In addition to the requirements specified in EN 10169-1, the following requirements shall apply. 6.1.1 Steel substrates The initial product for continuously organic coated steel flat products according to this European standard shall be steel strip with metallic coating complying with one of the following standards: EN 10292 or EN 10326 or EN 10327 If agreed at the time of enquiry and order the products may be supplied with other steel substrates. Minimum metal coating masses as specified for certain applications shall be indicated at the time of enquiry and order. NOTE The mechanical properties of the substrate material can be altered by the coil coating process. The use of substrates which can be subject to ageing will result in an increase in yield point and tensile strength, reduction in elongation and the possibility of appearance of Luders lines and the occurrence of fluting effects. 6.1.2 Organic coatings 6.1.2.1 Coating materials The more common coating materials used on the exposed sides of organic coated flat products suitable for building exterior applications, together with their coating thickness (dry film thickness) are given in Annex A of EN 10169-1:2003. 6.1.2.2 Coil coating systems The type of coating on either side of the product shall be agreed between the purchaser and the supplier to meet the purchaser's requirements of the product flexibility, the corrosion protection category of the top and reverse sides and the UV resistance category of the top side. NOTE The reverse side coating should be chosen as appropriate. It is normally required to withstand handling and storage. In some circumstances, it can also be required to provide corrosion protection and/or aesthetic appearance or to be compatible with foam or adhesive bonding. For strip supplied in coil form, the top side is normally the outside of the coil; for sheets and cut lengths (in stacks or bundles) the top side is normally uppermost. If the purchaser requires an alternative arrangement, this shall be expressively stated at the time of enquiry and order.



EN 10169-2:2006 (E) 9
6.1.2.3 Temporary protection treatment Coil coated products can be supplied with the additional temporary protection of a strippable film. Additional temporary protection is recommended, when special requirements during transportation, storage or processing are expected. The type of temporary protection shall be agreed upon at the time of enquiry and order. Type and thickness of the coating shall be taken into consideration when choosing protective films. NOTE 1 The user should ensure proper stock rotation to maintain easy removal of strippable films. NOTE 2 Outdoor weathering exposure time of coated products protected by strippable films should be strictly limited. 6.1.3 Manufacturing process Within the context of the data on coil coating (see 6.1.2.2), the details of the manufacture of the product is at the discretion of the manufacturer. 6.2 Coating properties 6.2.1 Properties which form part of factory production control 6.2.1.1 Dimensions and shape The tolerances on the thickness of the substrate and the width, length, flatness, edge camber and out-of squareness of the organic coated steel flat product shall be as specified in EN 10143. NOTE It should be indicated at the time of enquiry and order if the normal or special tolerances as covered by the above mentioned standard apply. 6.2.1.2 Thickness of the organic coating The tolerances on the ordered coating thickness specified in EN10169-1:2003, Table 2 shall apply. NOTE For definition of coating thickness and nominal/specified coating thickness, see also EN 10169-1. 6.2.1.3 Colour Appropriate colour tolerances, the method of measurement and the measurement device shall be agreed at the time of enquiry and order. NOTE
Metallic and pearlescent paints exhibit directionality. It is important that this directionality is maintained to ensure colour consistency.
6.2.1.4 Gloss When required the tolerances shall be as given in Table 3 of EN 10169-1:2003. 6.2.1.5 Adhesive strength after cupping or bending For liquid coatings with a thickness up to 60 µm, one of the following requirements applies, the choice is left at the discretion of the manufacturer. a) no loss of adhesion after taping for an indentation depth of 4 mm. b) no loss of adhesion after a 2 T bend test.



EN 10169-2:2006 (E) 10 For other liquid coatings and solid films, for the maximum indentation depth that will not rupture the substrate, peeling shall not exceed 75 %. 6.2.2 Performance properties
6.2.2.1 General The performance properties are evaluated by so called performance tests. The performance tests are only carried out for the purpose to classify the coatings into categories. 6.2.2.2 Product flexibility Product flexibility shall be evaluated by a T-bend test carried out on the exposed face in accordance with 7.5.6. The flexibility of the other face may be evaluated by agreement at the time of enquiry and order. The minimum bending radius without cracking ranging from 0 T to 8 T shall be specified at the time of enquiry and order. 6.2.2.3 Durability 6.2.2.3.1 General Durability of coil coated products involves resistance to corrosion in a variety of outdoor environments as well as behaviour on weathering and may be verified by appropriate tests (see 7.5.8).
