Hot-rolled and cold-reduced electrolytic zinc-coated carbon steel sheet of commercial and drawing qualities
ISO 5002:2013 specifies the characteristics of carbon steel sheet of commercial and drawing qualities in cut length or coil form, zinc coated by electrolytic deposition. Electrolytic zinc-coated sheet is intended for the manufacture of formed or of miscellaneous parts, and can be supplied chemically treated to render it more suitable for painting. The zinc coating is expressed in micrometres of thickness per side, for equally coated, differentially coated, or one-side-coated sheets. These sheets are generally produced with coatings, which are not intended to withstand outdoor exposure without chemical treatment and painting. Electrolytic zinc-coated sheet can be produced in thicknesses of 0,36 mm and thicker (normally up to 4,0 mm) and in widths of 600 mm and over in coils or cut lengths. It is recognized that materials thinner than 0,36 mm or thicker than 4,0 mm can be suitable for electrolytic zinc coating, and, if required, be the subject of agreement between the interested parties.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives

INTERNATIONAL STANDARD ISO 5002:2013(E)
Hot-rolled and cold-reduced electrolytic zinc-coated
carbon steel sheet of commercial and drawing qualities
1 Scope
This International Standard specifies the characteristics of carbon steel sheet of commercial and drawing
qualities in cut length or coil form, zinc coated by electrolytic deposition. Electrolytic zinc-coated sheet
is intended for the manufacture of formed or of miscellaneous parts, and can be supplied chemically
treated to render it more suitable for painting. The zinc coating is expressed in micrometres of thickness
per side, for equally coated, differentially coated, or one-side-coated sheets. These sheets are generally
produced with coatings, which are not intended to withstand outdoor exposure without chemical
treatment and painting. Electrolytic zinc-coated sheet can be produced in thicknesses of 0,36 mm and
thicker (normally up to 4,0 mm) and in widths of 600 mm and over in coils or cut lengths. It is recognized
that materials thinner than 0,36 mm or thicker than 4,0 mm can be suitable for electrolytic zinc coating,
and, if required, be the subject of agreement between the interested parties.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 6892-1, Metallic materials — Tensile testing — Part 1: Method of test at room temperature
ISO 7438, Metallic materials — Bend test
ISO 16160, Hot-rolled steel sheet products — Dimensional and shape tolerances
ISO 16162, Cold-rolled steel sheet products — Dimensional and shape tolerances
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
electrolytic zinc-coated steel sheet
product obtained by electrolytic deposition of a zinc coating on steel sheet on a zinc coating line to
produce either electrolytic zinc-coated coils or electrolytic zinc-coated cut lengths
3.2
skin pass
light cold rolling of hot-rolled descaled sheet or of the cold-reduced and annealed steel sheet prior
to zinc coating
Note 1 to entry: The purpose of the skin pass is to produce a higher degree of surface smoothness and thereby
improve the surface appearance. The skin pass also temporarily minimizes the occurrence of a surface condition
known as stretcher strain (Luders lines) or fluting during the fabrication of finished parts. The skin pass also
controls and improves flatness. Some increase in hardness and loss of ductility will result from skin passing.
3.3
stabilized interstitial free steel
extra low carbon steel in which all interstitial elements are combined with titanium and/or
equivalent elements
3.4
grade substitution
interstitial free steel (IF steel) may be applied on orders specifying CR4
Note 1 to entry: Deep drawing special killed, provided that the customer is informed of the substitution and
related shipping documents reflecting the actual material shipped.
3.5
lot
50 t or less of sheet of the same designation rolled to the same thickness and condition
4 Dimensions
4.1 The thickness of zinc-coated sheet can be specified as a combination of the base metal and metallic
coating, or as the base metal alone. The purchaser indicates on the order which method of specifying
thickness is required. In the event that the purchaser does not indicate any preference, the thickness as
a combination of the base metal and coating will be provided. Annex A describes the requirement for
specifying the thickness as base metal alone.
4.2 Electrolytic zinc-coated sheet less than 600 mm wide can be slit from wide sheet and will be
considered as sheet.
5 Conditions of manufacture
5.1 Steelmaking
The processes used in making the steel and in manufacturing electrolytic zinc-coated cold-reduced
sheet and hot-rolled sheet are left to the discretion of the manufa
