The intended surface treatment see table 1 and the anodizing method to be used see subclause 5. The following groups or looks of anodised surfaces are available: This document specifies the technical conditions of delivery for anodized products of wrought aluminium and wrought aluminium alloys, used preferably in metal finishing.

The anodised layer can be coloured in different ways. Components which have been treated by different anodizing processes shall not be batched together for testing. Sealing deposits which could impair the decorative appearance of visible surfaces shall either be prevented by additives to the bath, or subsequently removed. Smaller flaws on the surface are namely removed, a unified look is created and the surface is prepared for further treatment decorative diin. The versatile use of aluminium is assured with its suitable surface protection as the raw aluminium oxidizes very quickly on air.

Amendments This standard differs from the June edition as follows: If products are required for the purposes of comparison, the range of variation shall be defined by at least two limiting samples. Identify unmet needs and discover next-generation technologies Improve quality by leveraging consistent standards to dim din and market requirements Dni risk: Etching — satinising and pickling Etching is a chemical process, which happens in alkaline solutions.

In case of doubt, the German-language original should be consulted as the authoritative text.

September 20, Post categories: After degreasing the surface using steam or a non-corrosive cleaning agent, the surface is given sin mirror finish in a special chemical or electroplating bath. Surface defects are only slightly reduced, and corrosion spots may become visible. Electrochemical polishing Aluminium gains with it a shiny surface which is however very sensitive and therefore must proceed to the further treatment of anodizing as soon as possible. C, medium bronze; see Aluminium-Merkblatt O4 3.

Screen printing, tampo printing, engraving. Treatment E0 removes the natural oxide coating, leaving the metal largely intact. This standard is not included in any packages.

Mitigate liability and better understand compliance regulations Boost efficiency: Recommended layer thickness at anodizing. The surface appearance of products shall be in accordance with the technical delivery conditions given in the relevant standards see clause 1.

Top Categories Terms of Use. If the 176111 appearance of anodized components is to be assessed after installation, they shall be cleaned before inspection. Proceed to Checkout Continue Shopping. This standard does not cover products with coatings produced by hard 17161 or batch or coil anodizing, or products worked after anodizing.

Welds and extrusion seams may be visible after anodizing. IHS Standards Expert subscription, simplifies and expedites the process for finding and managing standards by giving you access to standards from over don developing organizations SDOs.

Other viewing distances shall be agreed between customer and supplier. Mechanical polishing produces a smooth and shiny surface, and only partly removes surface defects. Please first log in with a verified email before subscribing to alerts. Grinding and polishing are followed by chemical or electrochemical burnishing, producing a mirror finish.

Already Subscribed to this document. 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.

The process removes most surface defects but coarse abrasives may leave marks. 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. The customer and supplier shall agree on the procedures to be used for anodizing and coloration, but details shall be left to the supplier. All other methods involve considerable metal removal.

Corrosion spots which were almost invisible before treatment may become more apparent. Your Alert Profile lists the documents that will be monitored. 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: Need more than one copy?

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. With the insignificant din of material we achieve a smooth, bright surface without scratches and with high shine. Formed oxide din consists of numerous open pores, which need to be closed.

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 aluminium din gain a special look with the mechanical surface treatment, for instance with polishing and grinding.

The thickness vin the oxide layer depends on dinelectrolyte — H2SO4, din used and anodizing duration. Furthermore, for certain suitable alloys anodizing preserves the decorative appearance obtained through pretreatment as din Table 1.

17611 the case of coloured or dyed coatings, a different admittance may apply. 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.

The scope of other testing cf.
