Flat rolled aluminium standards
Discover the importance of flat rolled aluminium standards in ensuring product safety, quality, and lower costs.
What is a standard ?
A standard is a technical document designed to be used as a rule, guideline or definition. It is a consensus-built, repeatable way of doing something. Standards are created by bringing together all interested parties such as manufacturers, consumers and regulators of a particular material, product, process or service. All parties benefit from standardization through increased product safety and quality as well as lower transaction costs and prices.
European standards for aluminium products
The number of different kinds and types aluminum products the world has been growing steadily. These products have different properties and quality requirements. European standards reflect the current level of quality aluminum products and meet the technological capabilities of its producers. It is now published more than 120 European standards for aluminum products.
European standards, for aluminum products in particular, characterized by clarity and transparency. Supplier and the customer should include references to standards when ordering products or contract. It gives both sides the necessary basis for negotiations in the event of a possible, when the customer is not satisfied with the products supplied to him.
Frequent cause of claims for delivered products is a simple misunderstanding, special, if the language, which is used when placing an order for products, not the native language. It is therefore important to apply in order and contract the terminology for various types of aluminum products, which is used in the relevant European standards.
Flat rolled aluminium
Technical terms for aluminium products, which are used in European Standards, establishes a special international document [2].
Sheet
Term «sheet» is used for flat rolled aluminium products of rectangular cross-section with a nominal thickness of less than 6 mm, but not less 0,20 mm, which comes in the flat cut length.
Strip
The term «strip» applied to a flat rolled aluminium product with a rectangular cross-section less than the nominal thickness 6 mm, but not less 0,20 mm, which comes in rolls. Often, instead of «strip» term used term «coil».
Plate
The term «plate» applied to a flat rolled aluminium product of rectangular section with a nominal thickness of 6 mm 400 mm, which comes in a measured length.
Below are presented the European standards on flat rolled aluminium: sheets, tapes and plates, as well as the related aluminium products [3].
