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

[31]

1978 relating thereto (MARPOL), Annex VI: Prevention of Air Pollution from Ships , apply to all parties

involved in the transfer of bunkers.
In this document, the following verbal forms are used:
— “shall” indicates a requirement;

duties, the minimum documentation for a bunker delivery includes the following:
a) for the bunker tanker delivery:
1) safety checklist (see Annex C);
2) bunker requisition form (see Annex F);
3) non-cargo tank inspection form (see Annex G);
4) cargo tanks measurement/calculation form (see Annex H);
5) BDN (see 11.5);
