INTERNATIONAL STANDARD ISO 11336-2:2020(E)
Large yachts — Strength, weathertightness and
watertightness of glazed openings —
Part 2:
Glazed opening integrated into adjacent structure
(elastically bonded to bulkhead or shell) design criteria,
structural support, installation and testing
1 Scope
This document specifies technical requirements for direct adhesive bonding of glazing materials into
recesses forming part of the structure of the ship and into frames that are fastened to the structure of
the ship.
It is applicable to large yachts as defined in ISO 11336-1.
This document is limited to the bonding of independent glazed openings, where the bonded joint is
designed to withstand local loads (from external loads coming from weather and sea conditions,
internal impact loads from accidental passenger or cargo shifting, wind suction and accelerations due
to ship motions).
Bonding of glazed openings where the glazing material is subjected to loads from global ship motions
(bending, shear force and torsion), which are considered as structural glazed openings, are outside the
scope of this document. Quantitative identification of the global deflection is also outside the scope.
Additionally, this document is limited to bonding that exhibits elastic behaviour, and excludes rigid
bonding and nonlinear elastic bonding.
The design of the bonding for the following installation types is outside the scope of this document:
— fire protected areas;
— glazed bulwarks;
— underwater glazing;
— pool glazing;
— glazing for use in polar areas;
— unstepped IGUs.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
3.1
bonding material
adhesive material that is used to adhere or bond items together
3.2
bonding process
process to join two materials with an adhesive
3.3
bonded joint
joint between the glazing (3.6) and substrate, consisting of a bonding material (3.1) and a sealing
material (3.4) if required
3.4
sealing material
material used to cover and protect (where necessary) the bonding material (3.1)
Note 1 to entry: The sealing itself is not considered to be part of the adhesive bond.
Note 2 to entry: The following items can have a negative effect on bonding materials:
— UV Light,
— seawater,
— chemicals (from cleaning compounds and or biological degradation).
Unless the bonding is specifically designed to be resistant to the above items, it must be protected by a seal
or sealing material (3.4). The sealing material (if present) combines with the bonding to form a weather or
watertight seal.

ISO 11336-2:2020(E)

3.5
elastic bonding
bonding where the bonded joints (3.3) are capable of transferring forces and distributing stresses
evenly and show a high degree of flexibility (ability to return to its original shape after deformation)
Note 1 to entry: Its purpose is to hold the glazing (3.6) in place, and to maintain its attachment to the structure
(transmitting loads from the glazing to the ships structure). Additionally, it provides the watertight/weathertight
boundary, whilst allowing rotational deflection and expansion/contraction of the glazing and/or the supporting
structure.
3.6
glazing
transparent or translucent pane
3.7
glazed opening
opening in the hull, superstructure or deckhouse of a ship structure fitted with glazing (3.6)
3.8
independent glazed opening
glazed opening (3.7) where the mechanical behaviour of the pane can be considered independent from
adjacent structures
EXAMPLE Framed appliance (3.9).
3.9
framed appliance
independent glazed opening (3.8) where the glass is clamped into a frame structure consisting of a frame
and a mechanical retainer
Note 1 to entry: For a framed appliance, the weight of the glass is mainly kept by the frame and the retainer. A
rubber gasket or an adhesive is used in this construction to prevent the direct contact between glass and frame
and to achieve watertightness or weathertightness.
3.10
appliance
device made of glazing (3.6) and adhesive or frame, used to cover and protect an opening in the hull,
superstructure or deckhouse
3.11
glazed opening integrated into adjacent structure

from adjacent structures
EXAMPLE Pane bonded directly into a frame.
3.12
insulated glazing unit
IGU
glazing (3.6) made of multiple panes, either monolithic or laminated, separated by sealed gaps filled
with gas (air, argon, etc.)
3.13
stepped IGU
IGU (3.12) where one of the panes is fixed to the framing while the other pane is not supported by the
framing structure
Note 1 to entry: The bonding of stepped IGUs can be designed using the approach defined in this document.
Note 2 to entry: See Figure 1.

ISO 11336-2:2020(E)

3.14
unstepped IGU
IGU (3.12) where both panes are supported by the framing structure
Note 1 to entry: See Figure 1.
Key
1 stepped IGU
2 unstepped IGU
Figure 1 — Stepped and unstepped IGU glazing
3.15
bonded window
glazed opening (3.7) where the glass is attached to the adjacent structure by an adhesive

under load. Bonded windows can be used like a framed window in any position on board of a large yacht.
3.16
substrate
material from which the frame, hull or superstructure is constructed, which can include filler, primer,
and paint systems
EXAMPLE Steel, aluminium, fibre reinforced plastic (FRP), or wood.
3.17
surface preparation
process of treating the surface of a substance in order to increase its adhesion, which includes applying
components such as activators, cleaners and primers
3.18
UV protection
UV light blocking border, applied to the surface or within the laminate of the glazing, designed to
protect the bond from UV light
3.19
spacer
element used to support the glass weight and to secure positioning during installation and bond cure,
that is removed prior to the application of the sealing
3.20
setting block
element used to support the glass weight and to secure positioning during installation and bond cure,
left in place throughout the lifetime of the bonding but considered not to take any load
Note 1 to entry: The setting block must be chemically compatible and must have a shore hardness less than the
surrounding bonding and sealing.

ISO 11336-2:2020(E)

3.21
resting pad
element designed to support the glass weight and to secure positioning during installation, bond cure
and during the lifetime of the bonding
Note 1 to entry: A resting pad is left in place throughout the lifetime of the bonding, and must be chemically
compatible. It must have a shore hardness greater than the surrounding bonding and sealing, so as to support the
glass weight throughout the lifetime of the bonding.
3.22
bonding width
distance along the mating faces of the substrate and adhesive, and the adhesive and glazing (3.6)
Note 1 to entry: See Figures 2 to 4 for illustrative sketches.
3.23
bonding thickness
distance between the mating faces of the substrate and the glazing
Note 1 to entry: See Figures 2 to 4 for illustrative sketches.
3.24
sealing gap

adjacent glazing, measured in the plane of the glazing
Note 1 to entry: See Figures 2 to 4 for illustrative sketches.

5.1 General
A record of the bonding application guidance (see 8.1) and bonding installation procedures (see 8.2)
shall be provided and kept on board (see ISO 11336-3).
Where no previous information on the installed bonding is available and it is required to install new
bonding, compatibility tests shall be made (see ISO 11336-3).
The bonding material shall meet the minimum requirements specified in 5.3.
The simplified and approximated structural model of the bonding, considered in this document, is
made of two stress components: a uniaxial tensile or compressive component (σ) perpendicular to the
glass plane, and a shear component (τ) whose plane is perpendicular to the glass plane and applied at
the bonding surface. This is shown in Figure 5.
