Cross-Reference DIN 17611 Anodizing Standard
Treatment E0 removes the natural oxide coating, leaving the metal largely intact. Mechanical polishing produces a smooth and shiny surface, and only partly removes surface defects.
Degreasing It occurs in three levels: The thickness of the oxide layer depends on dincin — H2SO4, din used and anodizing duration. Continued on pages 2 to 6. The surface appearance of products shall be in accordance with the technical delivery conditions given in the relevant standards see clause 1. Screen printing, tampo printing, engraving.
Welds and extrusion seams may be visible 1761 anodizing.
This standard is not applicable for products with oxide layers produced for technical purposes after hard anodising, products with oxide layers produced after coil anodising and for products which have been shaped after anodic oxidation. In case of doubt, the German-language original should be consulted as the authoritative text.
Because of unavoidable technical variation, the same treatment may result in different surface effects.
Additional arrangements for protecting semi-finished products and components during transport, in storage and during assembly shall be agreed between supplier and customer. The scope of other testing cf.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Sealing shall be deemed satisfactory if the intensity of the stain corresponds to grades 0 to 2 on the scale given in the annex to DIN EN This standard specifies the technical delivery conditions for anodized di and wrought din alloy products which are widely used in the metalworking industry.
Account should be taken of contact points, excess widths and lengths, and of drainage holes in hollow sections. Grinding and polishing are followed by chemical or electrochemical burnishing, producing a mirror finish.
Components which have been treated by different anodizing processes shall not be batched together for testing. Sealing deposits which could impair the diin appearance of visible surfaces shall either be prevented by additives to the bath, or subsequently removed.
If the document is revised or amended, you will be notified by email. The thickness of the coating on the visible surface shall be measured to an accuracy of 0,2 m three to five times at each of at least five 71611, 0,5 cm 2 in area, and the mean of the measurements for each point determined.
The aluminium din gain a special look with the mechanical surface treatment, for instance with polishing and grinding. Page 4 DIN Reflectors, borders, cin car idn, sport requisites.
Grinding and brushing produce a uniformly shiny surface and remove surface defects and corrosion spots unlike treatments E0 and E6. Page 5 DIN By implementing etching-satinising process din surface gets tarnishing look, which varies according to type of aluminium alloy, state of surface, temperature and handling time.

Your Alert Profile lists the documents that will be monitored. If products are required for the purposes of comparison, the range of variation shall be defined by at least two limiting samples. For dated references, subsequent amendments to or revisions of any of these publications apply to this standard only when incorporated in it by amendment or revision. 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: Smaller flaws on the surface are namely removed, a unified look is created and the surface is prepared for further treatment decorative surface.
