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. Esch 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.
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.
International Standard ISO 90-1 was prepared by Technical Committee
ISOITC 52, Light gauge metal Containers, Subcommittee SC 4, Open-top
Containers.
This second edition cancels and replaces the first edition (ISO 90-1:1986),
which has been technically revised.
ISO 90 consists of the following Parts, under the general title Light gauge
metal Containers - Definitions and determination of dimensions and
capacities:
- Part 1: Open-top cans
- Part 2: General use Containers
- Patt 3: Aerosol cans
Annexes A, B and C of this part of ISO 90 are for information only.

Introduction
ISO 90 consists of three Parts which group definitions, methods for
determination of dimensions and capacities, as weil as tolerantes and
designations of rigid Containers made of metal with a maximum nominal
material thickness of 0,49 mm.
This patt of ISO 90 covers open-top cans as defined in 2.1 and is
applicable to both round and non-round cans.
Diameters for round open-top cans (beverage cans excluded) are specified
in ISO 1361.

Light gauge metal Containers - Definitions and determination of
dimensions and capacities -
Part 1:
Open-top cans
1 Scope
This patt of ISO 90 defines open-top cans and tan types, cross-sections, constructions, shapes, special features
and capacities of such cans. lt specifies methods for determining Cross-sections and gross-lidded capacities. lt also
specifies tolerantes on capacity and recommends an international designation.
2 Definitions
For the purposes of this part of ISO 90, the following definitions apply.
2.1 Open-top cans
2.1.1 open-top tan: Rigid Container made of light gauge metal with a maximum nominal material thickness of
0,49 mm, one end of which is double-seamed after filling [see figure 6 a)].
2.1.2 open-top tan for processed food products: Open-top tan, tight to liquids and gases, preventing
contamination of the contents by microorganisms after processing.
2.1.3 open-top tan for beverages: Open-top tan for liquid products to which gas is added during filling.
2.1.4 diaphragmed tan: Can having a double-seamed diaphragm ring at the top end and a plug which fits into the
ring [see figure 6 b)].
2.1.5 tan with easy-open end for food and beverages: Can having one end comprised of a sheet metal Wall
with a line of scoring forming a tear Strip or area and having a tab attached to the tear Strip or area for easy manual
severance thereof.
2.2 Cross-sections
2.2.1 round tan: Can with a circular cross-section (see figure 1).
2.2.2 non-round cans
2.2.2.1 rectangular tan: Can with a rectangular [see figure 2 a)] or Square [see figure 2 b)] cross-section.
obround tan: Can with a cross-section of parallel sides of equal length joined by two curved ends, which
2.2.2.2
may be semicircular [see figure 3 a)] or include different radii [see figure 3 b)].
2.2.2.3 oval tan: Can with an oval cross-section (see figure 4).

end (see figure 7).

2.4 Shapes
NOTE - Figures 8 and 9 apply to both round and non-round Cross-sections.
2.4.1 cylindrical tan: Can which has Cross-section of constant dimension from top to bottom, local variations
caused by special features such as beading, etc. being disregarded (see figure 8).

3 Determination of dimensions
3.1 Measurement of Cross-sections
3.1.1 Measure the internal body cross-section using a plug gauge, or derive it from the external cross-section
measured with a vernier caliper.
3.1.2 Measure the necked-in or step-sided opening cross-sections using a plug gauge applied to the internal cross-
section of the extremity to which the end is to be fixed.
3.1.3 Measure the opening cross-section of a cylindrical or tapered tan using a plug gauge applied to the internal
cross-section of the extremity to which the end is to be fixed.
3.2 Nominal Cross-sections
The nominal cross-section is determined by rounding the internal body cross-section (see 3.1 .l) or necked-in or
step-sided cross-section (see 3.1.2) to the nearest whole millimetre (if the first decimal is 5 or above, round up; in all
other cases, round down).
3.3 Measurement of height
See annex A.
3.4 Characteristic dimensions
Nominal cross-sections are characterized by the dimensions specified in 3.4.1 to 3.4.4.
3.4.1 Cylindrical round tan
Dimension D (see figure 1).
3.4.2 Cylindrical non-round tan
Dimensions A and B (see figures 2 to 5).
3.4.3 Tapered round tan
Dimensions D1 and 02, of which DI is the larger and 02 the smaller (see figure 13).
3.4.4 Tapered non-round tan
Dimensions Al, BI, A2 and &, of which Al and B1 are the larger and A2 and & the smaller dimensions (see
figure 13).
3.5 Special features
3.5.1 Necked-in cans
The cross-sections in the necked-in area shall be indicated as follows (see clause 6 and figure 13):
- for round cans:
hl - top end;
q\12 - bottom end;
- for non-round cans:
ANI x &I - top end;
ANI x &~2 - bottom end.
