Ductile iron pipelines — Polyethylene sleeving for site application

This document specifies the characteristics of polyethylene film, commonly called polyethylene sleeving, used as additional protection against corrosion for ductile iron pipelines, particularly when laid in aggressive soil conditions. This film, the efficiency of which has been proved by experience, takes the form of a sheet or tube fitted around the pipes and fittings, on-site, immediately before pipe-laying.

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.

This third edition cancels and replaces the second edition (ISO 8180:2006), which has been technically
revised. The main changes compared to the previous edition are as follows:
— recommended installation methods have been added;
— the references and presentation have been reviewed and improved.

appropriate product; if carbon black is used for this purpose, the addition shall be in the range of 2 %
to 3 % by mass.
Antioxidants may be added, but shall not be greater than 0,5 % by mass.
Any impurities in the polymer shall be less than 0,1 % by mass.
The product shall not contain any plasticizers or fillers.
4.3 Regenerated products
Regenerated products may be used provided they comply with the requirement of this document.
