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)

Introduction
Automatic watertight ventilation systems help to prevent ingress of water, which can also help to maintain
buoyancy of small crafts. The air space trapped in the compartment can provide buoyancy to help to keep
the boat afloat.

4 Requirements
4.1 General requirements
Where an AWVSS is installed on an inlet and/or outlet of the ventilation system, it shall automatically close
the inlet and/or exhaust openings within the conditions specified by the appliance manufacturer and fulfil
the requirements of Clause 5 (hydrostatic AWVSS) or Clause 6 (electric AWVSS).
Installation and operation instructions shall be provided with each AWVSS by the device manufacturer. The
following information shall be included in the instructions:
a) the minimum and maximum pressure value under which the AWVSS system will operate;
b) the installation location;
c) the angle of heel/trim conditions for AWVSS operation;
d) the opening section area of the equipment.
An AWVSS as a part of a ventilation system shall be installed in accordance with the relevant watertightness
requirements given in ISO 12216, ISO 12217-1, ISO 12217-2, ISO 12217-3 and ISO 11812.
The consequence of the closure of air-intake, including potential damages to the engine while running and/
or potential damages to its compartment, shall be considered by the small craft manufacturer.
Potential consequences of closing the air intake of an engine room with a running engine can include
following.
— Underpressure, leading to collapse of the AWVSS itself, of hatches, or of decks and/or bulkheads,
compromising integrity, initiating structural damage and potentially initiating total collapse of the craft.
— Underpressure, leading to misalignment and potential failure of shafting.
— Underpressure, leading to failure of (fuel) tanks ventilated from outside.
— Loss of propulsion power because of stalled engine
NOTE It is possible that the engine will not be able to restart due to hatches sucked closed.

The user shall verify proper functioning of AWVSS on a regular basis, and if applicable, every time before
leaving port.
All parts of the AWVVS shall be easily ins
