1 Scope
This European Standard specifies the method to be used to verify the mechanical performance of Structural
Sealant Glazing Systems.
It applies to any window/doorset or curtain walling application (see Annex A).
Structural Sealant Glazing can be incorporated into the product as follows:
 either vertically; or
 up to 83° from the vertical (positive slope)
 up to 15° from the vertical onto the building face (negative slope).
NOTE A wall has a positive slope if its outer surface faces upwards.
It 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 profile (anodized and coated aluminium, stainless steel), the
glass coated or not which shall be bonded, the sealant and mechanical restraints when required.
The testing does not apply to other framing materials.

The assembling of the glass elements into or onto the window, door or curtain-walling framework shall be in
accordance with EN 13022-2, clause 4.
For requirements of the setting block material see Annex B.
4.3 Structural sealant
The structural sealant shall be identified and assessed according to EN 15434.
4.4 Anodised aluminium structural adhesion surface
4.4.1 Alloys of aluminium
The chemical composition of the aluminium alloy shall be recorded.
4.4.2 Characteristics of the anodising
The aluminium structural adhesion surface on which the tests in EN 15434 are to be performed, are identified
as follows.
4.4.2.1 Measurement of the thickness
At least one of the following methods shall be used:
 Eddy current test method to ISO 2360
 Split-beam optical method to ISO 2128
 Micro-section method to ISO 1463
 Gravimetric method to ISO 2106.
4.4.2.2 Sealing tests
At least one of the following methods shall be used:

equivalent in French is "colmatage" and in German "Verdichtung".
 Where cold sealing is proposed additional proof must be provided
NOTE 2 Details are prescribed on Qualanod ‘Sealing by hydrothermal treatment’ or ‘Cold impregnation/Cold sealing
(CI-CS) based on nickel fluoride’.

6 Evaluation of mechanical and retaining devices
Devices are used to reduce danger in the event of bond failure and they may be required by national
regulations. Functions of devices are illustrated in Figure 1.

Type I: Mechanical transfer of the self-weight of the infill to the sealant-support frame and thence to the
structure. The structural seal transfers all other actions. Devices are used to reduce danger in the event of a
bond failure.
oSIST prEN 16759:2014
Type II: Mechanical transfer of the self-weight of the infill to the sealant-support frame and thence to the
structure. The structural seal transfers all other actions and no devices are used to reduce danger in the event
of bond failure.
Type III: The structural seal transfers all actions including the self-weight of the infill to the sealant support
frame and thence to the structure. Devices are used to reduce danger in the event of a bond failure.
Type IV: The structural seal transfers all actions, including self-weight of the infill to the sealant support frame
and thence to the structure. No devices are used to reduce danger in the event of bond failure.

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.
NOTE Some provisions may require mechanical retaining devices, e.g. for negative sloping surfaces.
6.1 Evaluation of mechanical devices by calculation
The structural adequacy of such supports is assessed using conventional 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 series EN 1991, 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
oSIST prEN 16759:2014
into mechanical devices shall be no greater than those specified within the appropriate materials standard
from which mechanical devices are made.
6.2 Evaluation of mechanical devices by testing
Where the design incorporates novel features the following test can be used.
