The intended surface treatment see table 1 and the anodizing method to be used see subclause 5.

By implementing 1611 process din surface gets tarnishing look, which varies according to type of aluminium alloy, state of surface, temperature and handling time. Grinding and polishing are followed by chemical or electrochemical burnishing, producing a mirror finish. As the voice of the U. Polishing Din is carried out automatically or manually.
It shall not exceed 20 S for uncoloured coatings. Sealing shall be deemed satisfactory if the intensity of the stain corresponds to grades 0 to 2 on the scale given in the vin to DIN EN Screen printing, tampo printing, engraving. Grinding produces a relatively uniform, but dull surface. Etching — satinising and pickling Etching is a chemical process, which happens in alkaline solutions.
The thickness of the coating on the visible surface shall be measured to an accuracy of 0,8 m at two points at least mm apart. We have no amendments or corrections for this standard. This can be prevented by further treatment before pickling, but it is advisable to treat and store the material so that corrosion cannot occur.

Page 4 DIN Additional arrangements for protecting semi-finished products and components during transport, in storage and during assembly shall be agreed between supplier and customer.
It is intended for anodizing diin bulky din of the highest quality with the emphasis on special xin, like the colour of stainless steel and anodizing bright surfaces.
Assessment of quality of sealed anodic oxidation coatings by measurement of admittance DIN EN Aluminium and aluminium alloys — Anodizing — Part 7: In dib way treated surface of aluminium is resistant to weather, mechanical and some chemical influences.
You may delete a document from your Alert Profile at any time. The customer and supplier shall agree on the procedures to be used for anodizing and coloration, but details shall be left to the supplier. Notation system for surface pretreatment Symbol E0 Type of pretreatment Degreasing and deoxidation Grinding Brushing Polishing Grinding and brushing Grinding and polishing Pickling Explanatory notes Surfaces are degreased and deoxidized before anodizing, leaving any faults such as indentations and scratches visible.
This document does not apply to products with oxidation coatings produced by hard anodic oxidation process for technical purposes, products with oxidation coatings produced by coil anodic oxidation process and products worked after anodic oxidation.
Components which have been treated by different anodizing processes shall not be batched together for testing. Subscription pricing is determined by: September 20, Post categories: If the document is revised or amended, you will be notified by email.
Cross-reference DIN anodizing standard
Treatment E0 removes the natural oxide coating, leaving the metal largely intact. This document specifies the technical conditions of delivery for anodized products of wrought aluminium and wrought aluminium xin, used preferably in metal finishing. Anodic oxidation generates an oxide coating on the surface of aluminium, which results in an increased resistance to corrosion.
Slight variations in shade due to differences in material and the production process are unavoidable. The aluminium din gain a special look with the mechanical surface treatment, for instance with polishing and grinding. Contact points are a result of the manufacturing process and cannot therefore be avoided. Estimation of loss of absorptive power of anodic oxidation coatings of sealing by dye spot test with prior acid treatment DIN EN Aluminium and aluminium alloys — Anodizing — Part 5: 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: Treatment in special pickling solutions after degreasing produces a satin or matt surface.
Cross-Reference DIN 17611 Anodizing Standard
This standard is not applicable for products with oxide layers produced for technical dij after hard anodising, products with oxide layers produced after coil anodising and for products which have been shaped after anodic oxidation. 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 points, 0,5 cm 2 in area, and the mean of the measurements for each point determined.
The customer and the works carrying out the treatment shall agree on the appearance required for rolled and extruded semi-finished products or components made from them.
Page 6 DIN The thickness of the oxide layer depends on dinelectrolyte — H2SO4, din used and anodizing duration. Grinding and polishing produce a smooth and shiny surface and surface defects are removed, as are corrosion spots still visible after treatments E0 and E6. This standard not cover: If the decorative appearance of anodized components is to be assessed after installation, they shall be cleaned before inspection.
Surface defects are only slightly reduced, and corrosion spots may become visible. In keeping with current practice in standards published by the International Organization for Standardization ISOa comma has been used throughout as the decimal marker.
Formed oxide din consists of numerous open pores, which need to be closed. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
