EN 13523-19:2011 (E) 5 Introduction In the past it has been common practice in the northern hemisphere to expose test panels at 45° facing South. Whilst this orientation is appropriate for degradation of the organic coating, investigations have shown that it has little bearing on the overall corrosion performance of the product when used in building applications. For example, the 45° facing South exposure takes no account of overhangs which produce unwashed areas; sheet overlaps; low pitched roofing, etc. The Outdoor Exposure Committee of European Coil Coating Association (ECCA) designed an exposure system which aligns more closely with "real life" situations and which is the basis of this part of EN 13523. Three panel orientations are specified: a) PANEL 1: 45° to horizontal facing South. The traditional orientation for evaluation of organic coatings: colour change, gloss change, chalking, etc.; b) PANEL 2: 90° to horizontal facing North, with an overhang for evaluating general corrosion on side cladding particularly in unwashed areas; c) PANEL 3: 5° to horizontal facing South. This panel which includes an overlap is principally for evaluating general corrosion in roofing applications. The selection of one or more panel designs and their corresponding orientations will be chosen according to the exposure data required. SIST EN 13523-19:2011

The actual design and material of manufacture is at the discretion of the individual taking into consideration the corrosivity on the exposure site. Similarly the method of fixing the panels to the rack is up to the individual, but they shall be fixed in such a way as to avoid bimetallic corrosion. The material to provide the overhang on the North-facing panel shall be manufactured from an inert rigid material such as polymethyl methacrylate 1) and shall give an overhang on the panel of approximately 65 mm (see 2 in Figure 4 a)). 4.2 Apparat
