Performance of the task The terrace glazing system was assembled to the steel test frame by the manufacturer. The test frame was mounted to the decompression chamber as to a front wall. The inner side of the balcony glazing system was facing outwards from the chamber. Tests were performed on June 16, 2010 Test conditions: temperature 23°C and relative humidity 50 %. The following tests were carried out to the balcony glazing system in the presented order.
1. The wind load , EN 12211, Windows and doors – Resistance to wind load – Test method was applied.
The balcony glazing system was submitted to the positive and negative test pressures as follows:
three pressure impulses of 1320 Pa, positive pressure increasing positive and negative pressure up to the level of
1200 Pa and the measurements of the frontal deflection of the glass units
50 cycles of 600 Pa positive and negative pressure impulses safety test with one negative pressure impulse of 1800 Pa and
one positive pressure impulse of 1800 Pa glass units were opened and closed and the operation of the
systems was inspected
The frontal deflection of the glass units was measured at the 1200 Pa positive and negative pressure at the points presented in the figure 3. The sequence of the testing is shown in Appendix 2.

2. The vertical and horizontal point load resistance, SFS 3304 Window, functional requirements, classification and testing was applied,
Principals of the loading tests are presented in the Appendix 3. One of the the glass panes was opened 30 and the vertical point load of 500 N was applied for 5 minutes to the upper corner of the latch side. The horizontal force of 200 N was applied three times for 5 minutes at a time to the lower open corner, the three other corners were supported, appendix 3. Operation of the pane was inspected after the test. 3. Pendulum-impact test, EN 12600 Glass in building. Pendulum test.
Impact test method and classification for flat glass was applied
The impact test was carried out according to the standard EN 12 600 by the impactor of 50 kg. In the wheels of the impactor there was an air pressure of 0.35 MPa. One impact from the drop height of 190 mm was applied in the middle of each pane. Both surfaces of each panes were impacted. Operation of the pane was inspected after the impacts.
Results 1. The wind load resistance
NIKA-Universal Balcony Glass Curtain System, 8 mm passed the wind resistance test unaffected. No permanent change in the structure of the system was observed after the test.
Opening, shutting and moving the glasses horizontally was able to be carried out after the test.
Frontal deflection of the glass under the negative and positive pressure of 1200 Pa is presented in the table 1.

2. The vertical and horizontal point load resistance
No breakage of the glasses of NIKA-Universal Balcony Glass Curtain System occurred, nor was any visible change in the system observed after the tests. Opening, shutting and moving the glasses horizontally was able to be carried out after the test.
3. The Pendulum-impact resistance
Glass panes of 710 mm x 1807 mm x 8 mm and the structure of NIKA-Universal Balcony Glass Curtain System passed the test carried out from the drop height level of 190 mm without any damage. Displacement of the lower lock from the profile was observed, otherwise the pane stayed still. Opening, shutting and moving the glasses horizontally was able to be carried out after the test.
Test results are valid only for the tested samples.

Wind load resistance test
The wind load resistance test method. The graph shows the three pressure pulses of 1320 Pa, changing positive and negative pressure of 1200 Pa, 50 pcs of impacts with negative and positive pressure of 600 Pa and a safety test with positive and negative pressure of 1800 Pa.
For the estimation of the corresponding wind velocities the following formula was applied:
pdyn = 0,5 v2 or v = (2 pdyn / 1,2) , where pdyn = pressure, Pa = N/m2
= air density (1,2 kg/m3) v = wind velocity, m/s According to the above formula the pressure pulses of 1320 Pa correspond the wind velocity of 47 m/s, the impacts with positive pressure of 600 Pa simulate the wind velocity of 32 m/s, positive pressure of 1200 Pa corresponds the wind velocity of 45 m/s as well as the safety test with the positive pressure of 1800 Pa simulate the wind velocity of 55 m/s.
