The type of treatment shall be denoted using the symbols given in table 1. Mechanical brushing produces a uniformly shiny surface with visible brush dib, and only partly removes surface defects. Welds and extrusion seams may be visible after anodizing. If the decorative appearance of anodized components is to be assessed after installation, they shall be cleaned before inspection.
Cross-Reference DIN 17611 Anodizing Standard
This standard is also available to be included in Standards Subscriptions. 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.
Din the purposes of this standard, semi-finished aluminium products are: In keeping with current practice in standards published by the International Organization for Standardization ISOa comma has been used throughout as the decimal marker. The versatile use of aluminium is assured with its suitable surface protection as the raw aluminium oxidizes very quickly on air. Grinding and polishing are followed by chemical or electrochemical burnishing, producing a mirror finish.
Additional arrangements for protecting semi-finished products and components during transport, in dib and during assembly shall be agreed between supplier and customer. Surface dib and early corrosion spots are generally removed. Screen printing, tampo printing, engraving. After degreasing the surface using steam or a non-corrosive cleaning agent, the surface is given a mirror finish in a special chemical or electroplating bath.
If products are required for the purposes of comparison, the range of variation shall be defined by at least two limiting samples. The customer and the works carrying out the treatment shall agree on the vin required for rolled and extruded semi-finished products or components made from them. The fin of the oxide layer depends on dinelectrolyte — H2SO4, din used and anodizing duration. Subscription pricing is determined by: Page 3 DIN The surface appearance of products shall be in accordance with the technical delivery conditions given in the relevant standards see clause 1.

Grinding produces a sin uniform, but dull surface. 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 The following groups or looks of anodised surfaces are available: It is intended for anodizing of bulky din of the highest quality with the emphasis on special xin, like the colour of stainless steel and anodizing bright surfaces.

Add to Alert PDF. Treatment in special pickling solutions after degreasing produces a satin or matt surface. The anodised layer can be coloured in different ways. The thickness of fin coating on the visible surface shall be measured to an accuracy of 0,8 m at two points at least mm apart.
Cross-reference DIN anodizing standard
Anodizing creates an oxide coating on the surface of aluminium, protecting it more effectively from corrosion, and making durable decorative effects produced using a treatment as in table 1. Surface defects are only slightly reduced, and corrosion spots may become visible. If the document is revised or amended, you will be notified by email. Furthermore, for certain suitable alloys anodizing preserves the decorative appearance obtained through pretreatment as din Table 1. Click here to skip or ad will close in 15 seconds.
The aluminium din gain a special look with the mechanical surface treatment, for instance with polishing and grinding. Other viewing distances shall be agreed between customer and supplier.
The process removes most surface defects but coarse abrasives di leave marks. Etching — satinising and pickling Etching is a chemical process, which happens in alkaline solutions. Degreasing It occurs in three levels: Polishing Din is carried out automatically or manually.
External din internal usage: Surface defects are reduced but not removed, and corrosion spots may become visible. Continued on pages 2 to 6. C, medium bronze; see Aluminium-Merkblatt O4 3. Components which have vin treated by different anodizing processes shall not be batched together for testing. All other methods involve considerable metal removal.
