27、ring (ISO 4628-2) 3 Terms and definitions For the purposes of this document, the definitions given in EN 13523-0:2014 apply. 4 Principle A test panel is exposed to continuous water condensation for a pre-determined time and at a specified temperature. The test panel is evaluated for any changes such

28、 as blistering or corrosion, e.g. red rust, white rust. Optionally, changes in colour and/or gloss are evaluated as well. 5 Apparatus Ordinary laboratory apparatus and glassware, together with the following: 5.1 Cabinet The apparatus consists essentially of an electrically heated water bath with tem

29、perature control and a cover designed to support the test panels which are placed at an angle of (60 5) to the horizontal, The tested face of the samples is facing down, the other face being exposed to the environment. If necessary, suitable inert blanking samples may be used to ensure the tightness

30、 of the chamber. The insulation of the cabinet shall be enough to guarantee constant temperature of the air space below the panels. An example for cabinet design is given in Figure 1.

31、n of the humidity cabinet (cross view) 6 Sampling See EN 13523-0. 7 Test panels See EN 13523-0. The panels (usually 150 mm 100 mm) shall be flat and free from contamination. 8 Procedure 8.1 Exposure If specified, determine the gloss and colour before exposure. Position the test panels in the frame a

32、t an angle of (60 5) to the horizontal with the test surface facing down. Control the temperature of the water so that the temperature in the air space above the water is maintained at (38 2) C. Use deionised water, having a conductivity not greater than 0,5 mS/m and maintain the quantity of the wat

33、er throughout the test. Ambient temperature around the cabinet shall not exceed 23 C. Expose the test panels for 500 h, 1 000 h or 1 500 h, unless otherwise agreed. DIN EN 13523-26:2014-08 EN 13523-26:2014 (E) 78.2 Evaluation At the end of the required exposure period remove the panels from the cabi

34、net, carefully wipe off surface moisture with a soft tissue and immediately conduct the final evaluation. If required, take pictures to record any change caused by exposure. Inspect the surface for blisters in accordance with EN ISO 4628-2. If specified, evaluate the gloss difference in accordance w

35、ith EN 13523-2 and the colour difference in accordance with EN 13523-3. NOTE Edges are not evaluated, as they could be affected by the frame. 9 Expression of results The results shall be expressed as: blistering in accordance with EN ISO 4628-2; gloss difference in accordance with EN 13523-2; colour

36、 difference in accordance with EN 13523-3. 10 Precision No precision data are currently available. 11 Test report The test report shall contain at least the following information: a) all details necessary to identify the product tested; b) a reference to this part of EN 13523 (EN 13523-26); c) the d

37、uration of the exposure, in hours; d) the results of the test, as indicated in Clause 9; e) any deviation from the test method specified; f) any unusual features (anomalies) observed during the test; g) the date(s) of the test.
