Hurricane missile testing device
During tropical hurricanes, but also during comparable extreme weather events, large and small flying objects are whirled up. The test equipment on display is suitable for impacting external wall components with large flying objects in accordance with standards.
Product description
The test method described in ASTM E1886-13a is currently used to test resistance to these missiles. Alternatively, ISO/AWI 16316 is currently being developed, which is available in the 2022 draft.
It describes a firing device for large wooden slats with a cross-section of 38.1 x 88.9 or 50 x 100 (W x H in mm) and lengths between 525 and 4000 mm, at speeds of 9 to 30 m/s on average. There is also an apparatus for small missiles for steel balls with a diameter of 8 mm.
To generate reproducible test results, ift MessTec GmbH uses a standard-compliant pressure accumulator with correspondingly prescribed pressure measurement technology. The launch velocity is measured at the muzzle using an HMG400 velocity measuring system. This makes it easy to achieve the required 2% measuring accuracy. The aiming points on the test specimen can be set with a laser depending on the lath dimensions and the required impact velocity.
The photometric calibration procedure with a high-speed camera can also be offered.
Product benefits
- use with height adjustment for single-storey components or lifting option for impacting facades.
- precise and reproducible adjustment and measurement in conjunction with laser pointing
- calibration standards with connection to national or international standards.
- standard-compliant with ASTM 1886-X1 and preparation for ISO/AWI 16316
