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 Note d. 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).

Small craft — Windows, portlights, hatches, deadlights and doors —
Strength and watertightness requirements
1 Scope
This International Standard specifies technical requirements for windows, portlights, hatches, deadlights and
doors on small craft of hull length up to 24 m, taking into account the type of craft, its design category, and the
location of the appliance.
The appliances considered in this International Standard are only those that are critical for the craft's
watertightness, i.e. those that could lead to flooding due to strength and/or watertightness,
Openings and non-opening devices fitted below Area I are excluded from the scope of this standard.

6.1.1.1 Plates in Area I
Simply supported plates shall not be used in Area I:
 on sailing monohulls in design categories A and B and sailing multihulls in design category A;
 on motor boats in design category A.
On other types of craft and design categories, simply supported plates may be used provided that all the
following conditions are met:
 the glazing material is PMMA or PC; (see clause 5)
 the plate thickness is equal to 1,3 times the one required by clause 7;
 the fixing devices of the plate (hinge bolts, fixing knob, etc.) are not spaced more than 250 mm.
The above restrictions of use need not be considered if the appliance is equipped with a deadlight meeting the
requirements of 6.3.6.
6.1.1.2 Flexibly connected plates
Flexibly connected plates may only be used on motor boats of design categories C and D in Areas III and IV.
6.1.2 Semi-fixed plates
6.1.2.1 Plates made of material other than glass
Semi-fixed plates may be used in boats of all design categories and in all location areas with the restrictions of
the special requirements given in 6.3.
This type of end connection can be achieved by one of the following means.
a) Connected with a counter frame: The edge fixity is achieved by pinching the plate at its periphery
between the boat shell or a frame and a counter frame. The counter frame shall be mechanically
fastened and/or glued to the structure of the boat.

b) Connected by gluing: The edge fixity is achieved by gluing the plate at its periphery to the boat shell,
to the structure of the boat or to a frame. This gluing can either be in a rabbet or a face, edge gluing or
any combination of these gluing methods.

c) Connected by direct fastening: The edge fixity is achieved by fastening the plate inside its periphery to
the shell, the structure of the boat or to a frame by correctly spaced and sized mechanical fasteners.
These fasteners may be bolts, rivets, self-tapping screws or any adequate mechanical fasteners.
Note 1 to entry: Even with the best fastening system, full edge fixity of a non-stiffened plate at its periphery
can never be achieved. Plates are therefore considered at best as semi-fixed.
