Endorsement notice The text of ISO 3211:2010 has been approved by CEN as a EN ISO 3211:2010 without any modification. “ DIN EN ISO 3211:2010-12 EN ISO 3211:2010 (E) 3 1 Scope This International Standard specifies an empirical method for assessing the resistance of anodic

    28、oxidation coatings to cracking by deformation. The method is applicable particularly to sheet material with anodic oxidation coatings of thickness less than 5 m, and is useful for development purposes. NOTE If the test piece is thick, even more than 5 m of coating can be measured (see Clause 6). 2 P

    29、rinciple A test piece is bent along a spiral, graduated with a radius of curvature index, using a simple instrument. The radius of curvature corresponding to the region where the first cracks in the oxide layer appear is determined and the percentage elongation of the test piece corresponding to thi

    30、s radius is calculated. 3 Apparatus 3.1 Measuring instrument, as shown in Figure 1, which includes the following elements. 3.1.1 Steel former, mounted on a suitable base, in the shape of a spiral, graduated in deformation indexes, E, from 1 to 18. These indexes, E, correspond to radii of curvature,

    31、R, as shown in Table 1, and are derived from Equation (1): R = 21 E (1) where R is the radius of curvature, in centimetres; E is the deformation index corresponding to the region where the first cracks appear. 3.1.2 Two screws, for clamping the ends of the test piece.

    33、Cut a strip of anodized aluminium having approximately the following dimensions: length: 25 cm; width: 2 cm; maximum thickness: 0,5 cm. 4.2 Determination Clamp one end of the test piece with the clamping screw 3 with the significant surface outwards. Bend the test piece progressively over the spiral

    34、, in such a way that the test piece remains in contact with the spiral, and clamp the other end with the second screw 5. Beginning from clamping screw 3, examine the anodic oxidation coating and mark the region where the first cracks appear. lf the cracks are difficult to detect, they can be rendere

    35、d visible using the procedure described in ISO 2085 by removing the bent test piece and immersing it in copper sulfate solution for 5 min, then rinsing and drying it. The test piece is then replaced on the apparatus and the deformation index corresponding to the region where the first cracks appear

    36、is marked. 5 Expression of results Express the elongation, A, of the anodized metal as a percentage using Equation (2): 1002dAR d=+(2) DIN EN ISO 3211:2010-12 EN ISO 3211:2010 (E) 5 where d is the thickness, in centimetres, of the test piece; R is the radius of curvature, in centimetres, given by Eq

    38、and the index, E, in the case of a thick test piece with an anodic coating greater than 5 m; e) anything unusual noticed during the determination; f) any operations not included in the procedure described in this International Standard, or considered to be optional; g) the date of the test.
