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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/DIS 11949:2013 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 9, Tinplate
and blackplate.

DRAFT INTERNATIONAL STADARD ISO/DIS 11949:2013

Cold-reduced electrolytic tinplate
1 Scope
This International Standard specifies requirements for single and double cold-reduced low-carbon mild steel
electrolytic tinplate in the form of sheets or coils.
In general, single cold-reduced tinplate is specified in nominal thicknesses that are multiples of 0,005 mm,
from 0,15 mm up to and including 0,60mm. Double cold-reduced tinplate is specified in nominal thicknesses
that are multiples of 0,005 mm, from 0,10 mm up to and including 0,36mm.
This International Standard applies to coils and sheets cut from coils in nominal minimum rolling widths of 600
1)
mm .
In addition, the general technical delivery requirements of ISO 404 are applicable.
2 Normative references

3 Definitions
For the purposes of this International Standard, the following definitions apply:

1) Nominal minimum rolling widths of 500 mm may be applied by agreement between the purchaser and the
manufacturer.

3.1
blackplate
cold-reduced low-carbon mild steel, applied for manufacturing electrolytic tinplate (refer to ISO 11951)
3.2
electrolytic tinplate
cold-reduced low-carbon steel sheet or coil coated on both surfaces with tin that is applied in continuous
electrolytic operation.
3.3
differentially coated electrolytic tinplate
cold-reduced electrolytic tinplate, one surface of which carries a heavier tin coating than the other.
3.4
single cold-reduced
term used to describe those products in which the blackplate has been reduced to the desired thickness in a
cold-reduction mill and subsequently annealed and temper rolled.
3.5
double cold-reduced
term used to describe those products in which the blackplate has had a second major reduction after
annealing.
