2 Sampling procedure ITC-CNR received the specimen on 2009-09-07. The specimen was sampled directly by the applicant who indicated its traceability on the basis of the previously described code. 3 Specimen preparation procedure The specimen was prepared in accordance with the provisions of standards EN 1026:2000, EN 1027:2000 and EN 12211:2000. The applicant placed the specimen in a supporting frame stiff enough to withstand the test pressures, and it was fixed as intended for use in the works without any twists or bends which may influence the test results and conditioned at controlled temperature and relative humidity within the range specified by the standards (between 10° C and 30° C and 25% to 75% RH respectively), for more than 4 hours immediately before test. The specimen was then fixed plumb to the test rig. Prior to testing the specimen was measured using a retractable tape measure. 4 Test method The performed and described tests were carried out on 2009-09-21 at ITC in San Giuliano Milanese (MI). 4.1 Air permeability The test was performed in accordance with standard EN 1026:2000 and with reference to EN 12207:1999. - Principle of test. The test consists in measuring the air permeability of the specimen subjected to an

established sequence of pressures. - Test procedure. In accordance with § 4.14 of EN 14351-1:2006, two tests were carried out

consecutively, one with positive pressures and one with negative pressures, in both cases according to the methods described below. The specimen’s opening parts were opened and closed once, then secured in the closed position. The test was subdivided into two different phases, each involving the same sequence, that is: measurement of the test chamber air permeability, applying the described sequence to the sample after completely sealing all its joints, then, after removal of all the seal, measurement of the overall permeability of the specimen and the test chamber. The air permeability of the test specimen at the different pressure levels was then obtained by calculating the mathematical difference between the two different measurements expressed in (m3/h). In both cases for this purpose, as foreseen by the test sequence, three pressure pulses, each 10% greater than the maximum test pressure, were applied with time to reach said maximum test pressure of not less than 1 second and pressure sustained for at least 3 seconds; air permeability was then measured and recorded with pressure applied in steps lasting at least 10 seconds, until reaching the maximum pressure of ± 600 Pa, according to the following sequence of absolute values: 50, 100, 150, 200, 250, 300, 450, 600 Pa. At each step, the result of the air flow measurements (Vx ) was adjusted in order to calculate air flow (Vo) at normal conditions (To=293 K, Po=101.3 kPa), considering the actual temperature (Tx ) expressed in °C and atmospheric pressure Px expressed in (kPa) measured during the test, in order to obtain:

4.2 Watertightness The test was performed in accordance with standard EN 1027:2000 and with reference to EN 12208:1999. - Principle of test. The test consists of constant, uniform spraying of a specified quantity of water onto the

external surface of the test specimen, while increments of positive test pressure are applied at the regular intervals specified hereafter, during which details are recorded of test pressure and location of water penetration in order to determine the window’s limit of watertightness.

- Test procedure. The opening parts of the specimen were opened and closed once, then secured in the closed position. Water was sprayed using a row of nozzles spaced at a centre-centre distance of 400 mm ± 10 mm with each nozzle spraying, on average, 2 l/min . The nozzle axis lies on a line (240+2)° below the horizontal line in accordance with method 1A. Spraying is applied first with the test pressure of 0 Pa for 15 minutes, then with the test pressure increasing every 5 minutes in steps of 50 Pa up to 300 Pa and from 300 Pa in steps of 150 Pa up to the specimen’s limit of watertightness.



4.3 Resistance to wind load The test was performed in accordance with standard EN 12211:2000 and with reference to EN 12210:1999. - Principle of test. The test involves the application of a defined series of positive and negative test

pressures at which measurements and inspections are made to assess relative frontal deflection and resistance to damage from wind loads.

- Test procedure. The test was split into three consecutive steps as illustrated below: deflection test (under positive and negative pressure), repeated pressure test and safety test.

- Deflection test – Positive pressure: Three air pressure pulses were applied, each 10% greater than the deformation pressure P1. The time to reach the maximum pressure is not less than 1 second, and it is sustained for at least 3 seconds. After setting all gauges for measuring frontal displacement to zero, incremental test pressures were applied to the specimen at a rate not exceeding 100 Pa/s up to pressure P1. Such pressure was sustained for 30 seconds during which the frontal displacement values of the characteristic points were measured and recorded. After reducing the test pressure to 0 Pa, at a rate not greater than 100 Pa/s and after (60 ± 5) s, the residual frontal deflections were measured and recorded.

- Deflection test – Negative pressure: Falling negative test pressures were then applied to the specimen down to pressure P1, following the same procedure adopted for the positive pressure test above.

- Repeated pressure test: The specimen was subjected to 50 cycles including negative and positive pressures at value P2, according to the following sequence: - first step is negative, next is positive as is the last of the sequence of 50 impulses; - variation from – P2 to + P2 and the reverse took (7 ± 3)s; - value P2 was maintained for (7 ± 3)s. After completion of the 50 cycles, the moving parts of the specimen were opened and any damage or functioning defects noted. The air permeability test was then repeated in accordance with standard EN 1026:2000 in the same manner as for the previous test.

- Safety test: The specimen was subjected to one cycle including negative and positive test pressure at maximum pressure P3, according to the following sequence: - negative test pressure was applied first; - variation from 0 Pa to – P3 and back from –P3 to 0 Pa took (7 ±3)s, maximum test pressure P3 was maintained for (7 ± 3)s; - the positive test pressure was applied after a (7 ± 3)s rest with the same sequence.

5 Test equipment The equipment used to perform the tests, in accordance with EN 1026:2000, EN 1027:2000 and EN 12211:2000, consists of: - a chamber with an open side to which the test specimen can be fitted; - a device for applying controlled test pressure between the faces of the specimen; - a device for producing rapid changes in test pressure, controlled within defined limits; - an instrument for measuring the quantity of air-flow into or out of the airtight chamber (Sensyflow IG); - an instrument for measuring the difference of pressure between the two faces of the specimen; - an instrument for measuring the temperature inside the airtight chamber; - instruments for measuring the atmospheric pressure, ambient temperature and relative humidity; - a spraying device capable of applying a continuous regularly dispersed film of water all over the test

surface by means of full circular cone nozzles with the following features: angle of spray °− )120(0

10 and flow rate 2 liter min/m2;

- an instrument for measuring and controlling the quantity of water supplied; - an instrument for measuring water temperature; - instruments for measuring displacements; - a means of positioning the measuring instruments in order to ensure their stability during the test.

6 Expression of results 6.1 Air permeability In accordance with § 4.14 of EN 14351-1:2006, the results obtained at each pressure step are expressed as the numerical average of the two air permeability values. In accordance with § 4 of standard EN 12207:1999 and with reference to EN 1026:2000, for the classification of the specimen the following criteria were also respected:

- air permeability adjusted as a function of the actual temperature and atmospheric pressure values, was related both to the overall area of the specimen (expressed in m3/m2h) and to the unit length of the opening joint (expressed in m3/mh) and the numerical average of the values obtained with the two air permeability tests under positive and negative pressure was therefore plotted for each test pressure step;

- the specified class was defined in accordance with the following table, at a reference test pressure of 100 Pa, where air permeability Q, permitted through the range of test pressures P, is determined using the following equation (where Q100 is the reference air permeability):

- on the basis of test results, the specified class was assigned when the measured air permeability did

not exceed the upper limit at any test pressure step in that class according to fulfilment of one of the following relations for the two curves, as shown in the log-log plot: - same class: the specimen is classified in that class; - 2 adjacent classes: the specimen is classified in the most favourable of these classes; - A difference of two classes: the specimen is classified in the mean class; - A difference of more than 2 classes: the specimen shall not be classified.

Table 2: Watertightness classes 6.3 Resistance to wind load In accordance with § 4, 5, 6 and 7 of standard EN 12210:1999 and with reference to EN 12211:2000, the specimen was classified on the basis of the tables below (where P1, P2, P3 values are linked to each other by the following relations: P2 = 0.5 P1 and P3 = 1.5 P1). In order to assign an overall classification to the specimen, compliance with the following requirements should also be verified prior to testing: - no visible failures shall be observed when viewed by normal or corrected vision at a distance of 1-meter

in natural light after both the first two tests (at P1 and P2 values); - the specimen shall remain functional and the air permeability, after tests P1 and P2, shall not exceed the

upper limits of the claimed air permeability class, by more than 20%; - the specimen shall withstand the safety test (at P3 value) although failures such as bending and/or

twisting of any hardware and splitting or cracking of framing members shall be permitted provided that no parts become detached and the test specimen remains closed. However if glass breaks, it is permitted for it to be replaced and the test to be repeated once more.
