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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at

Introduction
The ISO 8804 series is aimed primarily at scientists and academics training to become scientific divers
(at three levels of competency) and sets minimum requirements for the training of scientific divers at the
three levels reflected in the names of the three parts. It will be beneficial both to organizations involved in
training scientific divers and the scientific diving community as a whole.
This document is considered the minimum competency standard for recognition as a scientific diver. It is
intended to provide guidance regarding agreed-upon minimum training requirements, thereby easing
barriers to cross-programme co-operation and reciprocity through common acknowledgment of the basic
skill set for scientific divers.
Many organisations will have additional requirements for qualification of scientific divers. These
supplementary requirements could include, but are not limited to, a greater number of training dives,
additional training, enhanced fitness qualifications and requirements for maintenance of active diver status.
