EUROLAB laboratory provides testing and compliance services within the scope of EN 13583 standard. This European Standard specifies the resistance of flexible sheets for roof coverings using a simulated hail test. This European Standard can also be applied for waterproofing.
The test sample was thrown on the surface with a plastic ball of defined material and size. The support is made of steel or expanded polystyrene. The speed of the ball can be changed before the impact. The ball can be thrown vertically or horizontally.
The fixed support must be placed and attached in such a way that the device and the support will affect the test results due to the spring effect.
Pneumatic drive in which the ball velocity is controlled by the loading pressure displayed on a manometer.
Photocell/cells with time measuring device for measuring the effective velocity of the ball within (300 ± 400) mm from the surface of the test sample (30 to 0,5).
The polyamide (PA 6.6) plastic ball has a mass of (38,5 ± 0,5) g, a diameter of (40,0 ± 0,5) mm, and a smooth and defect-free surface.
A lawnmower used to provide firm or soft support of the test specimen.
Rigid support consisting of (500 ± 2) mm x (300 ± 2) mm x (20,0 ± 0,5) mm steel plate as base plate steel, technical specifications according to prince 10025-2, steel grade S235, JR quality , sand paper is laid on it according to the following technical specifications:
The sandpaper should be placed transverse to the machine direction of the roofing sheet sample (machine direction). The temperature of the steel plate should be (10 ± 2) °C
The test sample is placed with its surface against the support. The ballast plate with a (200 ± 2) mm opening is placed on the sample. The test sample should cover the opening with an excess.
The sandpaper should be placed transverse to the machine direction of the roofing sheet sample (machine direction). The temperature of the steel plate should be (10 ± 2) °C
The test sample is placed with its surface against the support. The ballast plate with a (200 ± 2) mm opening is placed on the sample. The test sample must cover the hole with a gap of at least more than 25 mm. The test area of the sample is in full contact with a cooling device such as melt ice, cooling pack. The temperature of the cooling device should be (0 ± 2) °C The cooling device is removed from the test area after (180 ± 30) seconds and the test is performed within (5 ± 2) s. The polyamide ball should hit the surface of the test sample in the middle of the test area.
