Foreword
This document EN 10154:2002 has been prepared by ECISS/TC 27 "Surface coated flat products - Qualities,
dimensions, tolerances and specific tests", the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest
by November 2002.
This European Standard supersedes EN 10154:1996.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,
Sweden, Switzerland and the United Kingdom.
1 Scope
This European Standard specifies requirements for continuously hot-dip aluminium-silicon alloy coated flat products
made of low carbon steels for cold forming (see Table 1) or of structural steels (see Table 2) in thicknesses
£ 3,0 mm. The thickness is the final thickness of the delivered product after coating.
This European Standard applies to strip of all widths and to sheets cut from it (‡ 600 mm width) and cut lengths
(< 600 mm width).
The aluminium-silicon alloy coating is obtained by immersing the products in a bath containing 8 % to 11 % Si (also
referred to as type 1).
The available coatings, coating masses and surface qualities are given in 7.2 to 7.3 and Table 3.
The products covered by this European Standard are mainly used where heat resistance and corrosion resistance
are the most important factors.
This European Standard is not applicable to steel flat products with hot-dip coating of pure aluminium (normally
referred to as type 2 coating).
2 Normative references
This European Standard incorporates by dated or undated reference provisions from other publications. These
normative references are cited at the appropriate points in the text, and the publications are listed hereafter.
Subsequent amendments to, or revisions of, any of these publications apply to this draft European Standard only
when incorporated in it by amendment or revision. In the case of undated references, the most recent edition of the
publications referred to applies (including amendments).

3 Terms and definitions
For the purposes of this European Standard the following terms and definitions apply in addition to the terms and
definitions in EN 10020, EN 10021, EN 10079 and EN 10204.
3.1
hot-dip aluminium-silicon alloy coating (AS)
application of an aluminium-silicon coating by immersing the prepared products in a molten bath of aluminium-
silicon alloy
NOTE  In the present case, wide strip is continuously hot-dip coated in a bath the composition (type 1) of which is given in
clause 1.
3.2

4 Classification and designation
4.1 Classification
4.1.1 The steel grades according to Table 1 of this European Standard are classified according to their
increasing suitability for cold forming as follows:

DX52D+AS: drawing quality,
DX53D+AS: deep drawing quality,
DX54D+AS: special deep drawing quality,
DX55D+AS: deep drawing quality, heat resistance up to 800 °C,
DX56D+AS: extra deep drawing quality.
The steel grades according to Table 2 of this European Standard are classified according to their decreasing
specified minimum yield strength valu
