Furthermore, for certain suitable alloys anodizing preserves the decorative appearance obtained through pretreatment as din Table 1.
The aluminium din gain a special look with the mechanical surface treatment, for instance with polishing and grinding. Welds and extrusion seams may be visible after anodizing. Sealing shall be deemed satisfactory if the intensity of the stain corresponds to 176611 0 to 2 on the scale given in the annex to DIN EN Anodic oxidation generates an oxide coating on the surface of aluminium, which results in an increased resistance to corrosion.
IHS Standards Expert subscription, simplifies 177611 expedites the process for finding and managing standards by giving you access to standards from over standards developing organizations SDOs.
1711 Their location on visible surfaces shall djn agreed upon by customer and producer. Sealing deposits which could impair the decorative appearance of visible surfaces shall either be prevented by additives 1611 the bath, or subsequently removed. Grinding and polishing are followed by chemical or electrochemical burnishing, producing a mirror finish. With the insignificant din of material we achieve a smooth, bright surface without scratches and with high shine.
The decorative appearance of components shall be assessed by viewing them using diffuse daylight from the following distances, at right angles to the visible surface: Contact points are a result of the manufacturing process and cannot therefore be avoided.
Page 5 DIN If products are required for the purposes of comparison, the range of variation shall be defined by at least two limiting samples.
Page 3 DIN The process removes most surface defects but coarse abrasives may leave marks. Because of unavoidable technical variation, the same treatment may result in different surface effects. Amendments This standard differs from the June edition as follows: The surface appearance of products shall be in accordance with the technical dni conditions given in the relevant standards see clause 1.

We can do that by sealing process. For undated references, the latest edition of the publication referred to applies. Page 6 DIN Other viewing distances shall be agreed between customer and supplier.

Mitigate liability and better understand compliance regulations Boost efficiency: Din the purposes of this standard, semi-finished aluminium products are: Grinding and brushing produce a uniformly shiny surface and remove surface defects and corrosion spots unlike treatments E0 and E6. Add dim Alert PDF. If the decorative appearance of anodized components is to be assessed after installation, they shall be cleaned before inspection.
Grinding produces a relatively uniform, but dull surface. This standard does not cover products with coatings produced by hard anodizing or batch or coil anodizing, or products worked after anodizing. The type of treatment shall be denoted using the symbols given in table 1.
