Product Overview
This device is a performance testing equipment designed and
developed in accordance with the new standard "Classification and
Testing Method for Wind and Fragile Impact Resistance of Building
Curtain Walls and Doors and Windows" modified by foreign standards
such as ASTM E1886-2005 and ASTM E1996-2008. The detection object
is limited to the building curtain wall, exterior doors and
windows, and storm protection device specimens themselves, and does
not involve the connection parts between the building curtain wall,
exterior doors and windows, storm protection device, and other
structures. The device is designed with simplicity, easy assembly,
adjustable and controllable pressure, adjustable launch height, and
convenient experimental operation.

GBT29738-2013 "Classification and Testing Methods for Wind and
Fragile Impact Resistance of Building Curtain Walls and Doors and
Windows"
[Technical parameters]
1. Environmental temperature: -10 ℃~50 ℃;
2. Air cannon working pressure: 0.4-0.8MPa;
3. Environmental temperature: -10 ℃~50 ℃;
4. Steel ball requirements: mass 2g ± 0.1g, diameter 8mm;
5. Steel ball launch speed: 39.7m/s
6. Rated voltage of solenoid valve: AC 220V;
7. The detection device consists of a projectile, a launch device,
a speed measuring device, and a passive pressure box
8. The wooden block is made of pine or cork, with a dry density of
500kg/m³ ± 25kg/m³, a cross-sectional height of 38mm ± 1mm, and a
width of 89mm ± 1mm. One end of the wooden block specimen is called
the impact end, and the other end is called the end;
[Product Features]
This device uses two photoelectric sensors of the same model, and
records the time when the emission passes through the two sensors
through an electronic timer. The response frequency of the
electronic timer shall not be less than 10KHz, and the response
time shall not exceed 0.15ms. The velocity of the projectile is
calculated by dividing the distance between two photoelectric
sensors by the time recorded by the electronic timer.
