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 electrote chnical 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 11336-1 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee

SC 12, Ships and marine technology — Large yachts.

ISO 11336 consists of the following parts, under the general title Large yachts — Strength, weathertightness

and watertightness of glazed openings:

— Part 1: Design criteria, materials, framing and testing of independent glazed openings

— Part 2: Glazed opening integrated into adjacent structure (directly bonded to the bulkhead or shell), design

criteria, structural support, installation and testing
— Part 3: Quality assurance, installation and in-service inspection

— Part 4: Non-linear / direct calculation methods for large windows (to be completed)

— Part 5: Glazed bulwarks, barrier and protective glazing for marine application (to be completed)

FINAL DRAFT INTERNATIONAL
ISO/FDIS 11336-1:2012(E)
Large yachts — Strength, weathertightness and watertightness
of glazed openings — Part 1: Design criteria, materials, framing
and testing of independent glazed openings
1 Scope

This part of ISO 11336 specifies technical requirements for independent glazed openings on large yachts, taking

into account navigation conditions, and the location of the opening.

Large yachts are yachts with length of the hull, LH, higher or equal to 24 m, in use for sport or pleasure and

commercial operations.

This part of ISO 11336 is suitable for the design of glazed openings on all large yachts. However where yachts

carry more than 12 passengers the additional requirements (set by the appropriate marine administration) for

fire integrity and damage stability are outside the scope of this standard.

The opening and the associated closing appliances considered in this part of ISO 11336 are only those that are

above the deepest waterline (dsw) and are critical for the ship integrity related to weathertightness and

watertightness, i.e. those that could lead to ingress of water in the hull in case of rupture, dislocation or loss of

the pane or its mounting. The scope of the scantling determination methods in 5.6 of this part of ISO 11336 is

related to and limited to independent glazed openings in which the pane is supported solely by simple linear

support at the edges Glazing in which the rotation at the edges is constrained more than it would be by a single

bond line in accordance with Part 2 of this standard is not covered by the methods defined in 5.6..

NOTE This part of ISO 11336 is based on the experience of ship window and glass manufacturers, shipbuilders and

authorities who apply to ships the regulations of SOLAS, as amended, and of the International Convention of Load Lines,

as amended, noting the provisions by the SOLAS Protocol of 1988, Article 8, as agreed by the appropriate Marine

Administration, and on the experience gained with application of the Large Commercial Yacht Code and RED Yacht Code

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 6345 and the following apply.

3.1
glazed opening

opening in the hull, superstructure or deckhouse of a ship structure to be fitted with a transparent or translucent

material
3.2
independent glazed opening

glazed opening where the mechanical behaviour of the pane can be considered independent from adjacent

structure because the pane is mounted in such a way that it is isolated from deformations of the supporting

structure, and the only loads on the pane are lateral pressure and effect of gravity and inertia.

3.3
not independent opening

glazed opening where the mechanical behaviour of the pane cannot be considered independent from adjacent

structure, e.g. pane bonded directly into a seat in such a way that it is carrying in-plane loads or is subjected to

out-of plane deformations of the supporting structure.
3.4
appliance

device made of a pane and a fixing system, used to cover an opening in the hull, superstructure or deckhouse
