English version of DIN EN 10 029

Warmgewalztes Stahlblech von 3 mm Dicke an; Grenzabmaße, Formtoleranzen, zulässige Gewichtsabweichungen

Supersedes DIN 1543, October 1981 edition.

European Standard EN 10 029 : 1991 has the status of a DIN Standard.

A comma is used as the decimal marker.

National foreword

This standard has been prepared by ECISS/TC 12.

The responsible German body involved in the preparation of this standard was the Normenausschuß Eisen und Stahl (Steel and Iron Standards Committee), Technical Committee 20/1 Maßnormen für warmgewalzte Flacherzeugnisse.

The content of this standard was previously issued for public comment in July 1989 in the form of a draft Standard to which the following principal amendments have been made.

1. The number of classes for the tolerance on thickness has been increased to four (cf. subclause 7.1.1 and table 1). This requires the class to be given when ordering.
2. The special flatness tolerances (cf. table 5) have been differentiated according to plate width.

The DIN Standards corresponding to the European Standards referred to in clause 2 of the EN are as follows:

European Standard	DIN Standard
EN 10 079	DIN EN 10 079
EN 10 163	DIN EN 10 163 Parts 1 to 3

Editor's note

This standard reproduces the official text of the English version of EN 10 029 as issued by CEN. In its preparation for publication as DIN EN 10 029 (English version), certain points have been noted which we consider to be in need of correction. These have been marked ^). The suggested amendments are given below and will be forwarded to the responsible CEN Secretariat for its consideration.

In presentation, orthography, punctuation and hyphenation, the aim has been to implement the PNE Rules consistently. Obvious errors (e.g. redundancies and omissions) have been rectified without further reference.

Suggested amendments

1. In the title and text of the standard, 'steel plates' should preferably read 'steel plate' in those cases where reference is made to the semi-finished product.
2. In table 6, third column, the heading should read either 'thickness tolerances' or 'tolerances on thickness'.
3. In subclause 10.5, u is the out-of-squareness (and not 'out-of-square') value.
4. To facilitate comprehension, in clause 11, item 3, 'class S' should preferably be set in brackets.

Foreword

This draft European Standard has been drawn up by ECISS/TC 12 'Structural steel and steels for pressure purposes, flat products — Dimensions and tolerances' whose Secretariat is held by NNI.

This document was originally drawn up as an EURONORM under the European Coal and Steel Community. With the formation of ECISS and the establishment of the ECISS work programme, TC 12 was asked to prepare this document for eventual publication as a European Standard.

This European Standard replaces:

EURONORM 29-81 Hot-rolled plates 3 mm thick or above — Tolerances on dimensions, shape and mass

ECISS/TC 12 met in February 1990 in Brussels and agreed on the text for circulation for formal vote within CEN. The following countries were represented in that meeting: Austria, Belgium, France, Germany, Italy, Netherlands and UK.

The Coordinating Commission (COCOR) of ECISS agreed on 1990-12-04/05 to submit this draft European Standard to the CEN Formal Vote.

According to the Common CEN/CENELEC Rules, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

1 Scope This European Standard specifies requirements for tolerances for hot rolled non-alloy and alloy steel plates +) including stainless steels with the following characteristics: a) nominal thickness: ≥ 3 mm ≤ 250 mm; b) nominal width: ≥ 600 mm; c) specified minimum yield strength: < 700 N/mm2. Tolerances for products of width ≤ 600 mm cut or slit from plate should be agreed between manufacturer and purchaser at the time of enquiry and order. This European Standard does not apply to round plates +), sketch plates +), chequer or raised-droplet pattern floor plates +) and wide flats for which other EURONORMS exist or European Standards dealing with tolerances on products of steel are being prepared: — Tolerances on dimensions, shape and mass for hot-rolled wide flats of steel (see EURONORM 91) 1). 1) Until this EURONORM is transformed into a European Standard, it can either be implemented or reference made to the corresponding national standard, the list of which is given in annex A to this European Standard.

2 Normative references EN 10 079 Definition of steel products EN 10 163-1/3 Delivery requirements for surface condition of hot-rolled plates, wide flats and sections of steel; 3 Definition For the purposes of this European Standard, the following definition applies: plate: see EN 10 079. 4 Information to be supplied by the purchaser 4.1 General The following information shall be supplied by the purchaser at the time of ordering: a) description of the product (plate); b) number of this European Standard (EN 10 029); c) nominal thickness, in millimetres; d) the tolerance class required (A, B, C or D) (see 6.2 and 7.1); e) nominal width, in millimetres;

f) the letters NK if plate with mill edges is required (see 7.2.2); Option 1. g) nominal length, in millimetres; h) the letter G if plate with limited edge camber and out-of-squareness is required (see 8.1); Option 2. i) the letter S if plate with special flatness tolerances is required (see 8.2). Option 3. Where no specific choice is made by the purchaser concerning points c, d, e and g, the supplier shall refer back to the purchaser. 4.2 Options A number of options are specified in clause 11. In the event that the purchaser does not indicate his wish to implement any of these options, the supplier shall supply in accordance with the basic specification (see 6.2). 5 Designation The designation of products in accordance with 4.1 shall also include the exact designation of the ordered steel grade. Examples of designation: a) Plate according to this European Standard with a nominal thickness of 20 mm, class A thickness tolerance, a nominal width of 2000 mm, with trimmed edges, a nominal length of 4500 mm, with normal flatness tolerances, of steel Fe 360 B, as specified in EN 10 025: Plate EN 10 029 - 20A × 2000 × 4500 Steel EN 10 025 - Fe 360 B b) Plate according to this European Standard with a nominal thickness of 4,5 mm, class B thickness tolerance, a nominal width of 1500 mm, with mill edges (NK), a nominal length of 2800 mm, with special flatness tolerances (S) and an edge camber limited to 0,2 % of the actual length and an out-of-squareness limited to 1 % of the actual width (G), of steel X 10 CrNi 18 9, as specified in EURONORM 88: Plate EN 10 029 - 4,5B × 1500 NK × 2800 S G Steel EURONORM 88 - X 10 CrNi 18 9

6 Form of supply 6.1 Plate shall be supplied: a) with thickness tolerances of class A, B, C or D (see 7.1.1); b) with trimmed edges or with mill edges (NK) (see 7.2.2); c) with normal (N) or with special (S) flatness tolerances (see 8.2) 6.2 In the absence of information in the order or of code letters for the supply, plate shall be supplied as follows: — sheared or flame cut edges; — normal tolerances for flatness, class N (see table 4). 7 Tolerances on dimensions 7.1 Thickness 7.1.1 Tolerances on thickness are given in table 1. Plates may be supplied with either: — class A: for minus thickness tolerances depending on the nominal thickness; — class B: for a fixed minus tolerance of 0,3 mm; — class C: for all plus tolerances depending on the nominal thickness; — class D: for symmetrical tolerances depending on the nominal thickness. At the time of ordering, the purchaser shall indicate if class A, B, C or D tolerances are required (see 4.1). Additionally and within the tolerance limits on nominal thickness, the tolerances between minimum and maximum thickness of an individual plate given in table 1 shall apply to class A, B, C and D tolerances. 7.1.2 For permissible limits concerning surface imperfections and requirements for repair, EN 10 163 Parts 1 and 2 apply.
