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).

Introduction
This document was developed in response to maritime industry demand and International Maritime
Organization (IMO) request for a standard providing requirements for the design and testing of
electronic record books on ships. The industry momentum towards paperless systems enhances the
need of such a standard with technical and operational requirements for electronic record books.

3.1
administration
government of the State under whose authority the ship is operating
Note 1 to entry: With respect to fixed or floating platforms engaged in exploration and exploitation of the sea-bed

been met
Note 1 to entry: Analytical evaluations can be made by a relevant expert with the necessary education, skills
and/or experience to make an informed and reliable judgement concerning the presentation of information,
its appropriateness, and usability. It is used for the evaluation of properties which can be judged only in the
context of other information or knowledge which requires the tester presentation. Compliance is determined by
comparing the observed property to the requirement.
3.3
audit logging
logs recording user activities, exceptions, and information security events, where logs are kept for an
agreed period to assist in future investigations and access control monitoring
3.4
authorized person
operator with enough clearance to handle an electronic record book (ELRB) (3.12) appointed by the
ships master
Note 1 to entry: Each authorized person is registered on the electronic approval system (3.11), and the authorized
person is controlled by the personal name or another personal identification data such as the passport number.
3.5
automatic record
data input generated by any other electronic device integrated to the electronic record book (ELRB) (3.12)
3.6
back-up
means to make a duplicate copy of a file, program, etc. as a safeguard against loss or corruption of the
original
3.7 data
3.7.1
automatically collected data
data that has been collected and stored by automatic means but has not been approved by a human user
3.7.2
edit history data
history of changes in one record, including the editor, edited content and time and date of the edit
3.7.3
record book data
data entered manually by an authenticated user, or if based on automatically collected data (3.7.1) after
an authenticated user has verified it
Note 1 to entry: This data must be included in all output, backups, sending to VDR, etc.
3.7.4
signed record book data
data which is closed from editing after having been signed by the master
