regulations. Functions of devices are illustrated in Figure 2.
Type I: Mechanical transfer of the self-weight of the infill to the sealant support frame. The bonding seal
transfers all other actions. Devices are used to reduce danger in the event of a bond failure.
Type II: Mechanical transfer of the self-weight of the infill to the sealant support frame. The bonding seal
transfers all other actions and no devices are used to reduce danger in the event of bond failure.
Type III: The bonding seal transfers all actions including the self-weight of the infill to the sealant support
frame. Devices are used to reduce danger in the event of a bond failure.
Type IV: The bonding seal transfers all actions, including self-weight of the infill to the sealant support
frame. No devices are used to reduce danger in the event of bond failure.

Figure 2 —Principles of the different types of bonded glazing
The performance of the devices shall be assessed either from the results of tests or from calculations
which shall allow for the method of attachment to the frame and also consider a variety of designs. The
devices shall not themselves cause damage to the glazing.
7.2 Evaluation of mechanical self-weight supports and retaining devices by calculation
The mechanical adequacy of such supports may be assessed by calculations based upon the strength of
materials and testing will not be required.
The design principles are based on the structural Eurocode EN 1990. The actions are determined in
accordance with the structural Eurocode EN 1991 series, including the national annexes.
The engineering stresses shall be calculated in accordance with the appropriate Eurocodes taking into
account the nationally determined parameters relevant to the place of use. The engineering stresses
induced into mechanical devices shall be no greater than those specified within the appropriate materials
standard from which mechanical devices are made.

2 bonding sealant support frame
3 mechanical self-weight support
Figure 3 — Example of test on mechanical self-weight support
The test sample comprises a mechanical self-weight support connected to the bonding sealant support
frame. The test sample shall reproduce the shape, the assembly and the static load transfer as in practice,
representing the centre of the maximum thickness of the infill the manufacturer is willing to use.
A vertical force simulating the self-weight of the glass is applied at the theoretical centre of gravity of the
insulating glass unit by a mean, which guarantees that the line of action is vertical.

---------------------- Page: 14 ----------------------
SIST EN 16759:2021
EN 16759:2021 (E)
When loaded, the displacement of the mechanical self-weight support is measured (Figure 3) and the
vertical difference between two consecutive glass panes shall be less or equal than 1 mm. In case of
insulating glass units consisting of more than two panes of glass, the displacement shall be measured
between any two consecutive glass panes and shall be less than 1 mm.
7.3.3 Test on mechanical self-weight support and retaining devices
When retaining devices are assessed by test, the following method shall apply (see type I and III of
Figure 2).
The test apparatus shall accurately reproduce the manner in which the retaining device is loaded.
To test the failure of the bonding seal, a static test shall be undertaken.
At least five samples shall be submitted to tension until break, using a tension speed of 1 mm/min
(±0,1 mm). An excessive deformation of the retaining device under testing is considered as a break.
value shall be calculated by the formula:
The characteristic static breaking force F
u,5
FF −τ× s (1)
u,5 mean αβ
where
τ = 2, 46 (for 5 samples, fractile of 5 % and confidence level of 75 %; for greater number of
αβ
samples or different confidence and fractile levels see ISO 16269-6).
8 Verifications necessary in case of interchange of components
Components and materials of a bonded glazing may be specified in one of two ways, by reference to:
a) particular manufactured products, using brand names, part numbers, etc.
b) generic specifications such as harmonized European Standards.
It shall be ensured that with an interchange of a component, the new component does not have a negative
influence on the performance level or the working life of the bonded glazing.
For components specified as described according to way a), it shall be proven that new components have
the same characteristics as the ones they replace and that they have no detrimental effect on the
characteristics of the bonded glazing. Furthermore, it shall be ensured that the new component is
compatible with other components for the envisaged lifetime. Compatibility tests shall be performed to
ensure that the exchanged components do not have a negative influence or effect on the components with
which it interacts in the system.
For components specified as described in the way b), the origin shall have no influence on the
performance. When interchanging a component specified by the second way, a test regime shall be
established using experience and the Table 1.
If the final colour of the anodized surface is given by the sealing material (see 5.3.3.4), interchanges are
not possible and different colours need to be tested separately.
For coated surfaces, one colour of coating shall be chosen for all of the different adhesion/cohesion tests
required for a given configuration (see Annex C).
Changes of colour of product might affect the adhesion performance. Therefore, it is recommended to use
same colour, same gloss (±5 E in accordance to EN 12206-1), same finish, same powder or liquid coating,
from a single supplier and from a single coater.

1 Scope
This document specifies the method to be used to verify the mechanical performance of the bonded
glazing for doors, windows and curtain walling (see examples in Annex A) and its durability. The bonding
covered is only that between the glass and the metal surface.
NOTE 1 Bonded glazing was formerly known as structural sealant glazing SSGS.
This document covers bonded glazing incorporated into the product construction works as follows:
— either vertically; or
— up to 83° from the vertical (positive slope); or
— up to 15° from the vertical onto the building face (negative slope).
NOTE 2 A wall has a positive slope if its outer surface faces upwards.
NOTE 3 Specific additional safety provisions can apply nationally.
This document gives information to the manufacturer to comply with requirements regarding design,
factory production control and assembly rules.
The parts concerned in the testing are the metal surface (anodized and coated aluminium, stainless steel),
the glass coated or not which shall be bonded, the bonding sealant and mechanical restraints when
required.
This document does not apply to:
— other surfaces materials;
— direct glazing;
— glass-to-glass bonding and edge seal of insulating glass units (which are covered by EN 13022-1 and
EN 1279-5);
— adhesive tapes.
