4.2 Detailed description of the properties
Most properties in 4.1 are straight forward, but some require explanation or specification. This section
describes how properties can be determined.
4.2.1 Mechanical properties
The property values shall reflect values as obtained from 4-point bending test according to ISO 1288-3,
and to represent the load level at which there is 5 % probability of breakage.
The reference method to assess the results is using the Weibull distribution according to EN 12603. The
values given should represent the stress level corresponding to the lower 95 % probability curve at 5 %
fractile.
Alternatively this probability can be taken as the lower threshold of the 90 % confidence interval to the
t-Student distribution. This is the simplified method.
The product data sheet shall specify whether the statistic analysis of the results is carried out via the
standard Weibull method or the simplified t-Student method.
See Annex E for a further explanation of the reference method and the simplified method.
Where properties are derived from results of pressure tests, the results shall be corrected for
diaphragm effects and statistically processed to derive the 5 % probability of breakage load level.
4.2.1.1 Mechanical properties to be specified
Mechanical properties of laminates with interlayers causing partial collaboration between plies cannot
be expressed well in terms of stress and strain. For reasons of simple application, flexural strength and
flexural stiffness are therefore given in terms of thickness of a pane of monolithic TTG giving the same
properties:
— t , in mm, the thickness of a pane of marine grade TTG giving the same breaking strength as the
eq,σ
product;
— t , in mm, the thickness of a pane of marine grade TTG giving the same bending stiffness as the
eq,w
product.
For ease of reference and to support engineering, the actual bending properties shall be given also:
— M , in Nmm, the breaking moment per mm width;
f
— D, in Nmm , the bending stiffness per mm width.
4.2.1.2 Methods to derive mechanical properties of the product
1) For monolithic thermally toughened safety glass (TTG) in compliance with ISO 21005, in the
absence of other data, the following nominal mechanical properties can be assumed for a panel
with thickness t in mm:
act
t = t
eq,σ act
t = t
eq,w act
M = 20 × t
f eq,σ
D = 5 833 × t
eq,w
6 © ISO 2019 – All rights reserved
2) For monolithic material in general, material properties can be assumed as minimal values
permitted by the referenced standard for the material (for example EN 12150 or ISO 11963).
In the absence of other data, the following nominal mechanical properties can be assumed:
1/2
t = t × (120/0,05 probability breaking strength of material)
eq,σ act
1/3
t = t × (70 000/Young’s modulus of material)
eq,w act
M = 20 × t
f eq,σ
D = 5 833 × t
eq,w
3) For laminated glazing using glass plies and interlayers of material complying with a relevant
standard, computational methods as described in ISO 11336-1:2012, 5.6.3 or similar methods
described in the other parts of ISO 11336 can be used.
For application of ISO 11336-1:2012, 5.6.3, a shortest clear opening dimension a of 1 000 mm can be
assumed for the calculation of the mechanical properties.
1/2
t = t × (120/ CFS)
eq,σ eq,Pt1
t = t
eq,w eq,w,Pt1
with t and t representing t and t calculated per ISO 11336-1:2012, 5.6.3.
eq,Pt1 eq,w,Pt1 eq eq,w
M = 20 × t
f eq,σ
D = 5 833 × t
eq,w
Depending on the lamination process applied, the characteristic failure strength (CFS) of chemically
strengthened glass (CSG) can be changed significantly. Therefore, the strength of a laminate with
CSG plies shall be verified by testing as specified in ISO 11336-1.
4) For any material or laminates that
— feature structural plies of material other than glass, or
— feature different types of interlayers, or
— do not have otherwise documented mechanical properties,
mechanical properties shall be derived from 4-point bending strength tests carried out in
accordance with the method described in ISO 1288-3. Where the strength of the material is such
that breakage cannot be achieved with standard bending test machines, the distance between the
supporting rollers can be increased. The distance between the load rollers shall be kept constant.
Values of M , D follow directly from the test results.
f
t , t can be calculated as per Annex B.2.
eq,σ eq,w
The result of the 4-point bending test is expected to show a linear relationship between the load
on the rollers and the deflection, represented by a straight line in a load/displacement plot. When
the behaviour becomes non-linear, that is the plotted line is no longer straight, failure in any part of
the system shall be assumed. The failure point of the material shall be taken where the behaviour
becomes non-linear, i.e. where the plotted line is no longer straight.
4.2.2 Post failure behaviour
It is considered that application of glass elements onboard is subject to requirements for safe failure
being complied with. To enable designers to develop failure scenarios for the glass elements, information
shall be provided about the nature of the failure mode and the residual strength of the material.
The actual performance of a glass element after failure strongly depends on the fracture pattern,
the orientation, and the way of mounting of the glass pane. It is therefore not possible to give exact
predictions for the behaviour of a specific glass element, but characteristic behaviour in common
conditions can at least give basic input for development of failure scenarios.
Failure modes can be characterized related to behaviour after failure in typical application conditions:
— pressure test: vertical mounting; 4-sided simple support;
— 4-point bend test;
— impact test;
and can be categorized according to the following.
— Loss of shape (to indicate behaviour):
— none: permanent deformation is less than 1,0 % of the size of the pane. (‘Failure’ caused by
sample falling through supporting rollers in ISO 1288-3 test);
— bent: pane takes on permanent set greater than 1,0 % of the size but large and by remains in one
piece. Loss of weight is less than 5,0 % of unbroken pane;
— broken: pane separates into pieces with edge length typically not smaller than 0,30 times the
smaller dimension of the pane;
— fractured: between broken and fragmented;
— fragmented: pane disintegrates into particles with edges typically perpendicular to surface
and edge length as in TTG fragmentation test in EN 12150-1;
— shattered: pane disintegrates into particles smaller than in TTG fragmentation test in EN
12150-1.
— Loss of strength:
— negligible: load bearing capacity is not less than 90 % of undamaged pane;
— impaired: load bearing capacity is not less than 40 % of same for undamaged pane (typically 3
ply laminate with one broken layer);
— severely impaired: load bearing capacity is not less than 22 % of same for undamaged pane
(typically 2 ply laminate with one broken layer);
— self-sustaining: pane can sustain its own weight with a margin of 50 % (meaning it would
not easily collapse by itself and could be approached safely for adding support or controlled
removal);
— lost: pane is not self-sustaining and may collapse under its own weight and when not come
down already must be considered an immediate threat for its surroundings.
— Loss of collaboration/delamination (for laminated construction):
— none: the area where adhesion between glass and interlayer was lost is less than 1 % of the area
of the panel;
— impaired: adhesion lost over not more than 10 % of area of panel distributed along edge of panel
or along edges of shards;
— severely impaired: adhesion lost over between 10 % and 50 % of area of panel;
8 © ISO 2019 – All rights reserved
— complete: more than 50 % of area of panel delaminated.
— Loss of tightness:
— intact watertightness: when broken pane does not lead to leakage;
2 2
— minor: opening is less than 0,01 % of pane area (1 cm /m , practical implication: for deckhouse
windows needs attention but can do without regular monitoring);
2 2
— moderate: opening is less than 1 % of pane area (1 dm /m , as may be achieved with ‘emergency
blanking plates’ needs no fix but needs attention);
2 2
— substantial: opening is more than 1 % and less than 50 % of pane area (0,5 m /m , needs a fix
and monitoring);
— complete: opening is more than 50 % of pane area.
Where no information of failure modes is provided, the value ‘NPD’ (no performance defined) can be given.
NOTE A value ‘NPD’ generally leads to the least favourable option being assumed in failure scenarios. For
example, loss of shape is assumed as ‘shattered’ for scenarios concerning breach of watertight integrity and as
‘none’ for scenarios related to pane falling from upper tier on muster station below.
4.3 Dangerous substances
Materials used in products shall not release any dangerous substances in excess of either:
— the maximum permitted levels specified in the referenced standard for the material;
— the values mentioned in the IMO MEPC.197(62), 2011, Annex 3, as amended.
4.4 Durability
The following durability categories are defined in terms of exposure in a type A climate zone according
to ISO 877-1. These categories indicate the design lifetime of the product.
a) >25 years
b) 10–25 years
c) 5–10 years
d) specified period
Monolithic TTG and HSG can be considered category a).
Durability of compound glazing and monolithic non-glass products shall be determined in accordance
with ISO 527-2. The category stated shall reflect the period over which it is expected that:
— strength and stiffness will be not less than 90 % of the strength and stiffness stated in the product
data sheet,
— the failure modes (according to 4.2) of the compound, including the interlayer, will not change, and
— for glazing claimed suitable for fitting in a wheelhouse: deterioration of optical properties will not
be such that the glass can no longer be considered as ‘non-tinted and non-polarized’. (See 4.5).
4.5 Suitability for application on control positions
Only non-tinted and non-polarized clear glass with a transmission of at least 65 % (see ISO 3538) shall
be used.
5 Evaluation of conformity
5.1 General
Conformity to this standard shall be as a result of initial examination and factory production control in
accordance with 5.2 and 5.3.
5.2 Initial examination
The initial examination shall consist of the verification of the data in the product description.
Any testing done as part of the initial examination shall be done under supervision of a recognized
organization or at a test laboratory meeting the requirements of ISO/IEC 17025.
In the initial examination, results of previous tests can be taken into account.
When actual testing is required, then the initial examination shall be undertaken on samples
representative of the product taken from direct production or on prototypes produced with the same
method of production.
Whenever a change occurs in the raw material or the production process which would or could change
significantly one or more of the characteristics, the type tests shall be repeated for the appropriate
characteristics (see Annex C for criteria).
5.3 Factory production control
The production shall be controlled and monitored in accordance with EN 14449 or equivalent.
6 Marking and/or labelling
6.1 General
Any voluntary marking and/or labelling shall not cause confusion with respect to the mandatory
requirements.
6.2 Product marking
All glazing items are to be uniquely identified in a way to allow verification they are installed in the
intended location. The marking can be such that it can be removed after installation in the final location
and inspection of correct mounting.
This system shall be documented.
6.3 Product records
The manufacturer shall maintain a system in which each glazing item, by its identification or by location
of mounting if identification is removable, can be traced back to the records of its production.
This system shall be documented. Data shall be kept available for the lifetime of the product (see 4.4).
7 Information to be provided to the vessel
The manufacturer shall provide with every project the information to be supplied to the vessel, or to
the builder for delivery with the vessel, as given in Annex F.
The conditions of use of NPD will depend on the conditions of certification of the vessel and the
application of the glass elements on board.
10 © ISO 2019 – All rights reserved
The information on board should be self-containing, unambiguous, and not contain info not relevant to
the glazing installed on board.
8 Inspection during installation
All bonding to glazing shall be assigned one of the safety classes from Table 1.
The assigned safety class shall at least be as indicated in Table 4. A higher safety class may be assigned
depending on the situation and the arrangement.
If a case would fall in more than one class, the highest safety class (that is the one with the lowest
number) shall be assigned.
The assigned safety class of the bonding shall be listed in the documentation on board.
Design, execution and monitoring of the bonding shall be in accordance with DIN 2304 for the safety
class assigned.
The bonding process shall be documented, monitored and recorded. Annex G gives an example of forms
that can be used for the records.
Table 1 — Safety classes
Safety class Level of safety requirement
S1 High level
Failure of the bond
— directly or indirectly leads to an inevitable hazard to life or limb;
— results in a failure of the function, the effect of which most likely leads to an
inevitable hazard to life or limbs.
S2 Medium level
Failure of the bond
— can lead to a hazard to life or limb;
— results in a failure of the function, the effect of which probably involves
personal injury or results in major environmental damage;
— results in a failure of the function, the effect of which most likely involves
major damage to property.
S3 Low level
Failure of the bond
— results in a failure of the function, the effect of which probably does not
involve personal injury neither results in major environmental damage;
— results in a failure of the function, the effect of which affects comfort or
performance at the most;
— results in a failure of the function, the effect of which probably does not
involve major damage to property.
Table 1 (continued)
Safety class Level of safety requirement
S4 No safety requirement
Failure of the bond
— results in a failure of the function, the effect of which does not, under
foreseeable circumstances, involve personal injury neither results in
environmental damage;
— results in a failure of the function, the effect of which only affects comfort
or performance;
— results in a failure of the function, the effect of which does not involve major
damage to property.
Table 2 — Positions in vessel regarding water/weathertightness
Position The glazing is relevant for the water/weathertightness of the yacht and the lowest point
of the glazing is:
P1 Located in a position below L1.
P2s For side or aft facing positions aft of the forward 0,25×L: Located in a position at or above L1 but
below 150 mm above the deck closing the buoyant volume.
P2f For length positions other than P2s: Located in a position at or above L1 but below the higher of:
L2 or 600 mm above the deck closing the buoyant volume. (Forecastle deck)
P3s For side or aft facing positions aft of the forward 0,25×L: Located in a position at or above
150 mm above the deck closing the buoyant volume but below L2.
P3f For length positions other than P3s: Located in a position less than h above the upper position
std
where P2f would be required.
P4 Any position above P3s or P3f but below L3.
P5 Any position above L3.
P6 Glazing not closing openings to outside but relevant for safety of people or environment. (Rail-
ings, glass balconies).
P7 Any other glass part or component.
See also D.7 for more information.
Table 3 — Design levels
Design class Design level
D1 Without a risk analysis.
D2 Without additional protection in case of partially or complete failure of the bond.
D3 With additional protection against loss/loss of components but without additional protection
against water ingress in case of partially or complete failure of the bond.
D4 Without additional protection against loss/loss of components but with additional protection
against water ingress in case of partially or complete failure of the bond.
D5 With additional protection against loss/loss of components and with additional protection
against water ingress in case of partially or complete failure of the bond.

9 Lifetime inspections
9.1 General
To ensure the safety of the yacht and its passengers all windows in classes S1 and S2 shall be subjected
to inspections as indicated below.
9.2 Inspections
a) The glass, black border and sealant should be routinely checked when washing the yacht. Any
special observations are to be documented.
b) A bi-monthly visual inspection should be carried out and documented by experienced crew in a
logbook (e.g. the engineers log). See 9.6.
Inspection by external qualified people should be carried out:
c) within one year after delivery (or sooner as agreed with the manufacturer),
d) every five years to the same schedule as the classification societies survey schedule.
Handling of defects shall take account of the safety classes as defined in Tables 1 to 4.
9.3 Inspection of glazing
9.3.1 General
The inspection shall make a difference between the structural plies and the protective plies of glazing,
as identified in the information on board the vessel (
