EN 16002:2010 – Flexible sheets for waterproofing – Determination of the resistance to wind load of mechanically fastened flexible sheets for roof waterproofing

5 Sampling
The flexible sheets for roof waterproofing shall be sampled according to EN 13416. All additional materials to construct the test specimen such as fasteners, insulation, substrate, vapour control layers, shall be according to the sampling requirements of the relevant European harmonised technical specifications. If these specifications are not available, then sampling shall be done according to the instructions of the applicant.
6 Test conditions
The test specimen and the apparatus shall be conditioned for at least 16 h in an environment of (23 ± 5) °C prior to the test and used under the same conditions.
7 Apparatus and additional devices
7.1 Pressure (vacuum) chamber The internal length and width of the pressure chamber shall be according to 8.2. The height of the pressure chamber shall be such that the applied pressure is equally distributed and not affected by deformations of the test specimen. The pressure chamber shall be provided with one or more windows in such a way that the test specimen can be observed during testing. The pressure chamber shall be capable of resisting a suction pressure of 10 kPa. It shall be possible to create an airtight seal between the test specimen and the pressure chamber.
7.2 Fan including control and recording system
7.2.1 Fan and controlling equipment The combination of the fan and the controlling equipment (e.g. valve) shall be capable of producing the dynamic load cycles, as defined in 9.4.
7.2.2 Pressure measurement device The pressure measurement device shall have a measurement tolerance less than or equal to ± 1 % in combination with the registration apparatus used. NOTE The best attainable accuracy of measurement is 0,02 kPa, being the accuracy of measurement of the pressure gauge.
