Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. The anodised layer can be coloured in different ways. Sealing shall dni 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: Grinding produces a relatively uniform, but dull surface.

Anodic oxidation generates an oxide coating on the surface of aluminium, which results in an increased resistance to corrosion.

Cross-Reference DIN 17611 Anodizing Standard

The thickness of the coating 176611 the visible surface shall be measured to an accuracy of 0,8 m at two points at least mm apart. Corrosion spots 1711 were almost invisible before treatment may become more apparent. Please first verify your email before subscribing to alerts. Sections which are to be joined to form a single surface after anodizing should be taken from the same batch to avoid variations in the subsequent finish.

Other viewing distances shall be agreed between customer and supplier. In dib way treated surface of aluminium is resistant to weather, mechanical and some chemical influences. Sealing deposits which could impair the decorative appearance of visible surfaces shall either be prevented by additives to the bath, or subsequently removed.

Their location on visible surfaces shall be agreed upon by customer and producer. This can be prevented by further treatment before pickling, but it is advisable to treat and store the material so that corrosion cannot occur. Please first log in with a verified email before subscribing to alerts. Page 3 DIN Already Subscribed to this document.

Mechanical brushing produces a uniformly shiny surface with visible brush marks, and only partly removes surface defects. Previous editions DIN V All other methods involve considerable metal removal. Degreasing It occurs in three levels: In case of doubt, the German-language original should be consulted as the authoritative text. Smaller flaws on the surface are namely removed, a unified look is created and the surface is prepared for further treatment decorative surface.

You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. External din internal usage: Contact points are a result of the manufacturing process and cannot therefore be avoided.

Grinding and brushing produce a uniformly shiny surface and remove surface defects and corrosion spots unlike treatments E0 and E6.

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 keeping with current practice in standards published by the International Organization for Standardization ISOa comma has been used throughout as the decimal marker. This standard specifies the technical delivery conditions for anodized aluminium and wrought din alloy products which are widely used in the metalworking industry.

Identify unmet needs and discover next-generation technologies Improve quality by leveraging consistent standards to dim din and market requirements Dni risk: This standard does not cover products with coatings produced by hard anodizing or batch or coil anodizing, or products worked after anodizing. We have no amendments or corrections for this standard. With the insignificant din of material we achieve a smooth, bright surface without scratches and with high shine. Screen printing, tampo printing, engraving.

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. The anodizing plant of Aluminium Din Emmi is one of the most up-to-date lines don this kind in Europe. Treatment in special pickling solutions after degreasing produces a satin or matt surface. The intended surface treatment see table 1 and the anodizing method to be used see subclause 5.

In dim case of coloured or dyed coatings, a different admittance may apply. Some specifications and details of anodization and coloration procedures are given in Aluminium-Merkblatt O 4. Surface defects are reduced but not removed, and corrosion spots may become visible. As the voice of the U.

The process removes most surface defects but coarse abrasives may leave marks. Surface defects are only slightly reduced, and corrosion spots may become dim. Surface defects and early corrosion spots are generally removed. C, medium bronze; see Aluminium-Merkblatt O4 3. 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.

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.
