This document specifies tolerances on dimensions and shape for hot rolled uncoated narrow strip and cut lengths of non-alloy and alloy steel grades in accordance with Table 1. It is usually produced in thickness of 0,8 mm up to and including 16 mm and generally has a rolled width less than 600 mm but is also produced in rolled widths up to and including 720 mm. Hot-rolled narrow strip has a symmetrical thickness profile with tight crown tolerances and therefore cannot be compared to slit wide strip. This document also applies to hot-rolled strip for cold rolling. Table 1 — Field of application [...table not represented...] This document can also be used for other steels, e.g.: steels from standards not mentioned in Table 1. This document does not apply to: — continuously hot-rolled wide strip and plate/sheet cut from wide strip of non-alloy and alloy steels and narrow strip obtained by slitting wide strip (EN 10051); — hot-rolled patterned steel strip and plate/sheet cut from wide strip (see EN 10363); — uncoated or electrolytically coated cold rolled sheet and strip (see EN 10131); — hot-dip coated steel sheet and strip (EN 10143).

This European Standard specifies the grades of continuously hot rolled low carbon steel sheet and strip (in coils) for cold forming. Depending on its actual width, strip is classified as: - hot rolled wide strip if its width is greater than or equal to 600 mm; - hot rolled slit wide strip if its width is less than 600 mm. For each grade, it specifies the chemical composition and the mechanical properties. This European Standard is applicable to products of thickness not less than 1,0 mm and not exceeding 11 mm. This European Standard is not applicable to products covered by other standards, such as: - hot rolled products of non-alloy structural steels for general use (see EN 10025 all parts); - steel sheet for pressure purposes (see EN 10028 all parts); - steel sheet for welded gas cylinders (see EN 10120); - quenched and tempered steels (see EN 10083-1 and EN 10083-2).

This document applies to hot rolled and cold rolled non-coated steel flat products made of multiphase steels for cold forming. It covers cold rolled products of thicknesses t < 3 mm and hot rolled products of thicknesses t ≤ 6,5 mm. These products are delivered in sheet, hot rolled strip, slit hot rolled strip, cold strip, slit cold rolled strip or cut lengths obtained from slit wide strip. Flat products of multiphase steels for cold forming can be delivered with an electrolytic zinc coating according to EN 10152.

This document specifies the chemical composition limits of wrought aluminium and wrought aluminium alloys and form of products. NOTE The chemical composition limits of aluminium and aluminium alloys specified herein are completely identical with those registered with the Aluminium Association, 1525, Wilson Boulevard, Suite 600, Arlington, VA 22209, USA, for the corresponding alloys.

This document specifies a standard test method for determining the ability of metallic sheets and strips having a thickness from 0,1 mm up to 2 mm and a width of 90 mm or greater to undergo plastic deformation in stretch forming. For thicker materials and when only narrower strips are available, tools of specified dimensions are provided, in which case subscripts are used, as shown in Table 1.

This document specifies the tolerances on dimensions and form for aluminium and aluminium alloy extruded porthole tubes with an outside diameter (OD) from 8 mm to 450 mm (round tube, see Figure 1) or with a cross section contained within a circumscribing circle (CD) from 10 mm to 350 mm (other than round tube, see Figure 2), supplied in straight lengths. The temper designations used in this part are according to EN 515. This document only applies to tube produced by the tube porthole/bridge method. This document does not apply to: — extruded tubes produced by the seamless, die/mandrel method (EN 755-7); — tubes delivered in coils (EN 13957); — coiled tubes cut to length (EN 13957).

This document specifies the composition, property requirements and tolerances on dimensions and form for seamless round drawn copper and copper alloy tubes for heat exchangers, condensers, evaporators and desalination equipment. It is applicable to copper and copper alloy tubes supplied in the size range from 6 mm up to and including 76 mm outside diameter and from 0,5 mm up to and including 3 mm wall thickness. The sampling procedures and the methods of test for verification of conformity to the requirements of this document are also specified.

This document specifies the composition, property requirements and tolerances on dimensions and form for rolled, finned, seamless copper and copper alloy tubes for heat exchangers. It is applicable to copper and copper alloy tubes supplied in the size range from 6 mm up to and including 35 mm outside diameter; from 1 mm up to and including 3,5 mm wall thickness of the unfinned section; and with fin height up to and including 4,5 mm. The sampling procedures and the methods of testing for verification of conformity to the requirements of this document are also specified.

This document specifies the technical delivery requirements for

—   semi-finished products, hot formed (e.g. blooms, billets, slabs) (see NOTE 1),

—   bars (see NOTE 1),

—   wire rod,

—   finished flat products, and

—   hammer or drop forgings (see NOTE 1)

manufactured from the case-hardening non-alloy or alloy steels listed in Table 3 and supplied in one of the heat-treatment conditions given for the different types of products in Table 1 and in one of the surface conditions given in Table 2.

The steels are, in general, intended for the manufacture of case-hardened machine parts.

NOTE 1  Hammer-forged semi-finished products (blooms, billets, slabs, etc.), seamless rolled rings and hammerforged bars are covered under semi-finished products or bars and not under the term “hammer and drop forgings”.

NOTE 2  For International Standards relating to steels conforming with the requirements for the chemical composition in Table 3, however, supplied in other product forms or treatment conditions than given above or intended for special applications, and for other related International Standards, see the Bibliography.

This document specifies the requirements for hot-dip galvanized (hereinafter referred to as zinc coated) and zinc-aluminium coated high tensile wires, which are widely used in parallel wire cables or semi-parallel wire cables for suspension bridges, stay bridges and other structures involving the use of parallel wires.
