Foreword
This European Standard has been prepared by Technical Committee ECISS/TC 26 " Tinmill products
- Qualities, dimensions, tolerances and specific tests ", the secretariat of which is held by BSI.
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 September 2001, and conflicting national standards
shall be withdrawn at the latest by September 2001.
This European Standard replaces EN 10202:1989.
This European Standard revises and combines EN 10202:1989, Cold reduced electrolytic chromium/
chromium oxide coated steel and EN 10203:1991, Cold reduced electrolytic tinplate. EN 10203 is
withdrawn.
It is intended that the third European Standard in the present series, EN 10205:1992, Cold reduced
blackplate in coil form for the production of tinplate or electrolytic chromium/chromium oxide coated
steel, will be withdrawn.
COCOR (Coordinating Commission of ECISS) approved the work item to revise EN 10202:1989 at its
meeting in November 1996. The following countries agreed to participate: Belgium, France, Germany,
Italy, Netherlands, Norway and the United Kingdom.
The annexes A, F, G, H and I are informative ; the annexes B, C, D and E are normative. This
European Standard also contains a Bibliography.
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,
Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
1 Scope
This European Standard specifies requirements for tinmill products in the form of sheets or coils for
subsequent cutting into sheets. Tinmill products consist of single and double reduced low carbon mild
steel electrolytically coated with either tin (tinplate) or chromium/chromium oxide (ECCS).
Single reduced tinmill products are specified in nominal thicknesses that are multiples of 0,005 mm
from 0,17 mm up to and including 0,49 mm. Double reduced tinmill products are specified in nominal
thicknesses that are multiples of 0,005 mm from 0,13 mm up to and including 0,29 mm.
This European Standard applies to coils and sheets cut from coils in nominal minimum widths of
600 mm.
NOTE Standard width coils for specific uses, e.g. tabstock, may be slit into narrow strip for supply in coil
form.

3 Terms and definitions
For the purposes of this standard the following terms and definitions apply:
3.1
electrolytic tinplate
cold rolled low carbon mild steel sheet or coil coated on both surfaces with tin that is applied in
continuous electrolytic operation
3.2
differentially coated electrolytic tinplate
electrolytic tinplate, one surface of which carries a heavier tin coating than the other. In some cases
one surface may have no tin coating
3.3
electrolytic chromium/chromium oxide coated steel (ECCS)
cold rolled low carbon mild steel sheet or coil electrolytically treated to produce on both surfaces a
duplex film of metallic chromium adjacent to the steel substrate with a top layer of hydrated chromium
oxides or hydroxides
3.4
single cold reduced
a term used to describe those products where the steel substrate has been reduced to the desired
thickness in a cold reduction mill and subsequently annealed and temper rolled
3.5
double cold reduced
a term used to describe those products in which the steel substrate, after annealing, has had a
second reduction in excess of 5 %, using a lubricant
3.6
temper rolling
a secondary rolling process, in which the reduction is less than or equal to 5 %, normally carried out
dry
Page 5
3.7
standard grade
material in sheet form that, having passed line inspection, is suitable under normal conditions of
storage, for established lacquering and printing over the entire surface of the sheet and does not
contain any defect that renders the material unsuitable for its intended use (see line inspection 3.25)
3.8
second grade
material which represents the best sheets rejected from the standard grade but may contain sheets
exhibiting defects in surface appearance and shape of limited extent. Suitability for established
lacquering and printing over the entire surface of the sheet is not assured. Not normally available in
ECCS
3.9
batch (box) annealed (BA)
a process in which the cold reduced strip is heated in tight coil form, within a controlled atmosphere,
for a pre-determined time/temperature cycle
3.10
continuously annealed (CA)
a process in which cold reduced coils are unwound and heated in strip form within a controlled
atmosphere for a pre-determined time/temperature cycle
3.11
finish
the surface appearance of tinmill products is determined by the surface characteristics of the steel
base together with the condition of the coating which, in the case of tinplate, can be either flow-melted
or unflow-melted
3.11.1
flow-melting
a process by which the ‘as deposited’ tin is heated above its melting point of 232 °C and is quickly
quenched in cool water resulting in a composite coating iron/tin alloy and free tin which exhibits a
bright reflective appearance
3.11.2
bright finish
a finish resulting from the use of temper mill work rolls that have been ground to a high degree of
polish and, in the case of tinplate, together with a flow-melted tin coating
3.11.3
stone/fine stone finishes
finishes characterized by a directional pattern, resulting from the use of final mill work rolls that have
been ground to a lower degree of polish than those used for the bright finish, in the case of tinplate
together with a flow-melted tin coating
3.11.4
shot blast
a finish resulting from the use of temper mill work rolls that have been shot blasted
3.11.5
silver finish
a tinplate product resulting from the use of shot blasted temper mill work rolls and with a flow-melted
tin coating
3.11.6
matt finish
a tinplate product resulting from the use of shot blasted temper mill work rolls and with an unflow-
melted tin coating

3.12
coil
a rolled flat strip product which is wound into regularly superimposed laps so as to form a coil with
almost flat sides
3.13
bow
the residual curvature in sheet or coil such that the distance between the edges is less than the
appropriate sheet or coil dimension
3.13.1
longitudinal (line) bow
residual curvature in the strip remaining along the direction of rolling
3.13.2
transverse (cross) bow
a mode of curvature in the sheet such that the distances between its edges parallel to the rolling
direction is less than the sheet width
3.14
centre fullness (full centre, centre buckle)
an intermittent vertical displacement occurring other than at the edge of the sheet or coil when the
material is laid on a flat horizontal surface
3.15
short pitch camber
the deviation of the coil from a straight line forming its chord
3.16
edge wave
an intermittent vertical displacement occurring at the edge of a sheet or a sample from a coil when
laid on a flat horizontal surface

feather edge (transverse thickness profile)
the variation in thickness, characterized by a reduction of thickness close to the edges, at right angles
to the rolling direction
