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 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html
This document was prepared by Technical Committee ISO/TC 122, Packaging, in collaboration with
the European Committee for Standardization (CEN) Technical Committee CEN/TC 261, Packaging, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 15750-3:2002), which has been
technically revised.
The main changes are as follows:
— in 4.3, finish of the flanges, steel plugs, label rings and protection rings can now be chosen between
the purchaser and the supplier;
— in Annex C, the configuration and dimensions of zinc-alloy die cast plugs were deleted due to
obsolescence;
— in C.1, Figure C.1, the zinc-alloy plug is obsolete and has been replaced with the steel plug;
— in C.7, materials of washers for flanges and plugs can now be agreed between the purchaser and the
supplier.
A list of all parts in the ISO 15750 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

mechanical fixed steel insert with threads, closable with plugs made of steel, other metals or synthetic
materials such as plastics, ensuring a leaktight closing in drums
3.2
elastomer
macromolecular material which returns rapidly to its initial dimensions and shape after substantial
deformation by a weak stress and release of the stress

3.3
thermoplastics
plastics that are capable of being repeatedly softened by heating and hardened by cooling through a
temperature range characteristic of the plastics and, in the softened state, of being repeatedly shaped
by flow into articles by moulding, extrusion or forming
4 Dimens ions, materials and finish
4.1 The nominal pitch diameter and the pitch of the thread of the closures G 2 and G 3/4 shall conform
to ISO 228-1.
These closures shall fit GO gauges conforming to ISO 228-2.
4.2 The dimensions and materials of the closure systems shall be in accordance with the relevant
annexes for the closure type, i.e.:
— Annex A: octagonal base closure system (type A closure);
— Annex B: serrated base closure system (type B closure);
— Annex C: octagonal (G 2)/hexagonal (G 3/4) base closure system (type C closure).
4.3 The finish of the flanges, steel plugs, label rings and protection rings shall be chosen and agreed
between the purchaser and the supplier.
If for reasons of compatibility another finish of the closure system is required, the nature of the internal
and external finish should be agreed upon between the purchaser and the supplier.
5 De sign and construction
5.1 Flanges
The flanges shall be the mechanical inserted type and shall make a leaktight fit when inserted.
5.2 Plugs
The plugs shall be designed so that they can be inserted or removed by means of a simple tool.
The plugs shall have a wrenching insert projection welded to the bottom of the sump of the plug or have
a wrenching device formed as part of the plug.
The dimensions of the wrenching insert shall be such that the plugs can be operated by a universal tool
for steel and plastics plugs. Examples are shown in Annex D.
For recommended closing torques, see Annex E.
5.3 Capseals and o verseals
Capseals or overseals, when fitted, shall be the manual or pneumatic crimping type and shall have
provisions for customs sealing and evidence of tampering.
Capseals/overseals shall be so designed that they can be removed by means of a simple tool.
ISO 15750-3:2022(E)
5.4 Label rings and pr otection rings
Label rings and/or protection rings shall be designed so that, when fitted, they can be mechanically
inserted simultaneously with the flanges. Label rings shall have provisions for customs sealing.
NOTE Label rings and/or protection rings can provide adequate reinforcement for the flange insertion and
can protect the drum stock neck against corrosion.
