ISO/DIS 20848-2
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 20848-2 was prepared by Technical Committee ISO/TC 122, Packaging.

ISO 20848 consists of the following parts, under the general title Plastics drums:

 Part 1: Removable head (open head) drums with a nominal capacity of 113,6 l to 220 l

 Part 2: Non-removable head (tight head) drums with a nominal capacity of 208,2 l and 220 l

 Part 3: Plug/bung closure systems for plastics drums with a nominal capacity of 113,6 l to 220 l

Annexes A, B and C form normative parts of this part of ISO 20848.

Annexes D, E and F form informative parts of this part of ISO 20848 and will be deleted in the final ISO standard

(for further information – see Introduction).

ISO/DIS 20848-2
Introduction

Throughout the world a large number of plastics drums types with different dimensions and characteristics are

being used. The differences in location of the minimum filling opening and outer dimensions result in differences in

filling, handling and transportation.

This standard specifies the characteristics and dimensions of plastics drums which are of importance for the

worldwide safe handling and transport of substances and for the continued reuse of the drums during their life

cycle. Detailed performance requirements and the related test methods are not included as they depend upon the

specific application.

The members of ISO/TC 122/WG 8 would like to have a nation related overview on the present status and opinions

on preferred target options for tight head (plastics) drums with a nominal capacity of 208,2 l and 220 l and their

closure systems. WG 8 would like to propose "preferred target options" on dimensions for drums and closures in

the final ISO standard. For this reason the WG members prepared the questionnaires in Annexes D to F and would

like to ask the members of ISO/TC 122 to complete them and return them together with the voting form for this DIS.

The Annexes with the questionnaires will be deleted in the final ISO standard.

Where the drums are intended to be used for the transport of dangerous goods, attention is drawn to the regulatory

requirements which govern the transport of those goods in the countries concerned, including capseals/overseals

fitted in accordance with the certificate. Depending upon the mode of transport, this means meeting the

requirements of:
 UN (United Nations) – Recommendations on the transport of dangerous goods.

 ICAO (International Civil Aviation Organisation) – Technical Instructions for the safe transport of dangerous

goods by air.

 IMO (International Maritime Organisation) – International Maritime Dangerous Goods (IMDG) Code

This involves the certification and marking of the drums according to the Regulations.

DRAFT INTERNATIONAL STANDARD ISO/DIS 20848-2
Packaging — Plastics drums —
Part 2:
Non-removable head (tight head) drums with a nominal capacity
of 208,2 l and 220 l
1 Scope

This International Standard specifies the characteristics and dimensions of non-removable head (tight head)

plastics drums with a nominal capacity of 208,2 l and 220 l.
2 Normative references

The following normative documents contain provisions which, through reference in this text, constitute provisions of

this International Standard. For dated references, subsequent amendments to, or revisions of, any of these

publications do not apply. However, parties to agreements based on this International Standard are encouraged to

investigate the possibility of applying the most recent editions of the normative documents indicated below. For

undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC

maintain registers of currently valid International Standards.

ISO/CD 20848-3, Plastics drums - Part 3: Plug/bung closure systems for plastics drums with a nominal capacity of

113,6 l to 220 l
3 Terms and definitions
For the purposes of this standard, the following terms and definitions apply.
3.1
non-removable head (tight head) drum (TH)

flat-ended or convex-ended circular cross-section packaging with openings for filling and emptying in the head not

exceeding 70 mm in diameter
3.2
nominal capacity (NC)

capacity in litres which, by convention, is used to represent a class of drums of similar brimful capacities

3.3
brimful capacity (BC)

volume of water in litres held by the drum when filled through the filling orifice to the point of overflowing

NOTE Annex A (normative) specifies the method for measuring brimful capacity.
3.4
total capacity (TC)

volume of water in litres held by the drum when filled completely, i.e. following the removal of any air trapped in the

drum
NOTE Annex A (normative) specifies the method for measuring total capacity.
