Aliuminis ir aliuminio lydiniai. Reikalavimai, keliami susiliečiantiems su maisto produktais anoduotiems gaminiams

This document specifies requirements for coloured or uncoloured anodic oxidation coatings on wrought and cast products in aluminium and aluminium alloys for use in contact with food. These requirements cover the chemical composition of the bath, the sealing and the properties of the obtained anodic oxidation coatings. They do not cover dyestuffs and pigments but do cover the metallic deposits produced by electrolytic colouring.

Neardomieji bandymai. 5 mm arba storesnių plokščių plieno gaminių ultragarsinis bandymas (atspindžio metodas)

This document describes a method for the ultrasonic testing of uncoated flat steel product for internal discontinuities. This document is applicable to flat product in nominal thickness range of 5 mm to 200 mm of non-alloyed or alloyed steel, excluding austenitic or austenoferritic steels. However, this document can be applied to the latter types of steels provided that the difference between the amplitude of the noise signal and that of the echo detection threshold is sufficient for the limit fixed. This document also defines five quality classes for the flat product body (classes S0, S1, SA, S2 and S3) and five classes (E0, E1, E2, E3, E4) for the edges (see Clause 13). Other methods of testing (e.g. by phased-array) or other test equipment may be used at the manufacturer's discretion provided that they give identical results to those obtained under the conditions of this document. In the event of a dispute, only the method defined in this document shall prevail. Testing of flat product of thickness less than 5 mm or higher than 200 mm may be the subject of special agreements between the parties concerned. The inspection is normally carried out in the place of production or on the premises of the supplier. If specified on the order, the inspection takes place in the presence of the purchaser or his representative1. A list of equivalent terms in several European languages is given in Annex A.

Aliuminis ir aliuminio lydiniai. Lakštai, juostos ir plokštės. 2 dalis. Mechaninės savybės

This document specifies the mechanical properties of wrought aluminium and wrought aluminium alloy sheet, strip and plate for general engineering applications. It does not apply to semi-finished rolled products in coiled form to be subjected to further rolling (reroll stock) or to special products such as corrugated, embossed, painted, sheets and strips or to special applications such as aerospace, can stock, finstock, for which mechanical properties are specified in separate European Standards. The chemical composition limits of the alloys are specified in EN 573 3. Temper designations are specified in EN 515.
