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 16163 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 12, Continuous mill flat
rolled products.
This fourth edition cancels and replaces the third edition (ISO 16163:2010), which has been technically revised.
INTERNATIONAL STANDARD ISO 16163:2012(E)
Continuously hot-dipped coated steel sheet products —
Dimensional and shape tolerances
1 Scope
This International Standard applies to dimensional and shape tolerances for all continuously hot-dipped coated
steel sheet products.
2 Dimensional tolerances
Dimensional tolerances are given in Tables 1 to 9.
Table 1 — Thickness tolerances for commercial, drawing, drawing aluminium-killed,
extra deep drawing stabilized interstitial free, and structural quality coils and cut lengths

NOTE 1 Thicknesses up to 1,6 mm are generally produced with a cold-rolled substrate.
NOTE 2 When International Standards that reference this standard permit slitting sheet to less than 600 mm in width to be considered
as sheet, tolerances shall be subject to agreement.
a
Thickness tolerances for sheet in coil form are the same as for sheet supplied in cut lengths but, in cases where welds are
present, the tolerances shall be double those given over a length of 15 m in the vicinity of the weld.
b
Given the difference in tolerances and physical properties of hot-rolled and cold-rolled sheet products, the user and the supplier
may negotiate a specific type of substrate. The relationship between the coating mass, in grams per square metre, and the thickness,
in micrometres, can be retrieved from the respective standards.
c
For specified strength levels of R = 360 MPa and greater, tolerances are increased by 10 %, applying normal rounding-off
e
procedures.
d
Tolerances for grade 550 shall be as agreed upon between the purchaser and the manufacturer.
e
Thickness is measured at any point on the sheet not less than 25 mm from a side edge.
f
The specified thickness range captions apply as a specific value.
g
The tolerances provided in this table are based on normal thickness (tolerance over and under). For ordered thicknesses other
than nominal, the total tolerance is twice the tabled value and may be distributed as agreed upon between the buyer and seller.
