Ships and marine technology — Ships' ordinary rectangular windows

This International Standard specifies the classification of rectangular windows for ships (series, types and models), and gives the dimensions for interchangeability and construction, materials, tests, marking and designation of these rectangular windows. NOTE 1 This International Standard is based on the experience of ships' window and glass manufacturers, shipbuilders and authorities who apply to ships the Regulations of the International Convention for the Safety of Life at Sea, 1974 (SOLAS 1974), as amended, and of the International Convention of Load Lines, 1966, as amended.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 3903 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee
SC 8, Ship design.
This third edition cancels and replaces the second edition (ISO 3903:1993), which has been technically revised.

4 Classification
Rectangular windows shall be classified by series, types, models and nominal sizes in accordance with 4.1 to
4.4 respectively.
NOTE 1 A survey of standardized rectangular windows is given in 4.5 and Table 3.
Further classification characteristics are the material classes; see 6.1 and Table 12.
4.1 Series
4.1.1 Regular series (N)
Rectangular windows of the regular series shall contain a toughened safety glass pane that meets the
requirements of ISO 21005.
4.1.2 Fire-resistant series (P)
Rectangular windows of the fire-resistant series shall be provided for installation in “A” or “B” class divisions,
containing a glass pane that meets the requirements of ISO 5797.
Modifications to the construction and installation of the glassholder and main frame, as well as additional
testing and marking, shall be in accordance with ISO 5797.
4.1.3 Heated series (H)
Rectangular windows of the heated series shall contain a heated glass pane in accordance with ISO 3434.
NOTE Modifications of the construction of glassholder or main frame are to be observed; see 5.1.2.
4.2 Types
Ships’ ordinary rectangular windows may be of two types:
— Type E: Heavy-type rectangular window;
— Type F: Light-type rectangular window.
4.3 Models
Models shall be designated in accordance with the following principal characteristics:
— opening or non-opening model;
— opening direction of glassholder;
— type of fastening.
The various combinations of these, which are in accordance with the definitions in ISO 6345, are given in Table 1.
4.4 Nominal sizes
The nominal size is defined by the clear light dimension for width w and height h of the rectangular window,
1 1
in millimetres, and is identified by a code number; see Table 2.
4.5 Survey of types, models and sizes
A survey is given in Table 3 for all rectangular windows standardized in this International Standard. It applies
to window series N (regular), P (fire-resistant) and H (heated).

5 Technical requirements
5.1 General
Rectangular windows of all series, types, models and nominal sizes shall be manufactured to the requirements
(dimensions, materials, etc.) given in this International Standard. They shall be capable of meeting the test
requirements specified in Clause 7.
5.1.1 Rectangular windows for fire-resistant constructions
In addition, for rectangular windows for fire-resistant construction, the glassholder and the main frame shall be
made of a material that keeps its mechanical characteristics at the temperatures given in ISO 5797.
They shall be designed so that temperature gradients do not develop stresses in the glass which could
result in rupture.
5.1.2 Heated rectangular windows
For heated rectangular windows, deviations in the design of glassholder or main frame based on the thickness
of the heated glass pane, see ISO 3434, and the electrical connection shall be taken into consideration.
5.2 Dimensions
5.2.1 Main dimensions
The main dimensions of rectangular windows shall be as given in Figure 1 and Tables 4 and 5. The correlation
between nominal sizes and types and models shall be as given in Table 3.
NOTE 1 Figure 1 does not define the construction of any series, type or model of rectangular windows; it is given for the
indication of standardized dimensions only. The illustration shows an inwards opening side-hinged rectangular window.
5.2.2 Corner radii
The basic radius is the corner radius r of the clear light size; see Table 4.
