Building Curtain Wall Anti - Wind Debris Testing Equipment, Modified In Accordance With ASTM E1886-2005, ASTM E1996-2008

DX8683 ASTM E1886-2005 Building Curtain Wall Anti - wind Debris Testing Equipment

【Product Overview】

This device is a performance testing equipment designed and developed in accordance with the new standard "Classification and Detection Method of Wind and Debris Impact Resistance of Building Curtain Walls and Doors and Windows" modified in accordance with ASTM E1886-2005, ASTM E1996-2008 and other foreign standards. The test object is limited to the building curtain wall, external doors and windows and the storm protection device test piece itself, and does not involve the connection between the building curtain wall, external doors and windows, storm protection device and other structures. The device has a simple design, easy assembly, adjustable and controllable pressure, and adjustable emission height, which is convenient for experimental operation.

5. Launch speed of steel ball: 39.7m/s

6. Rated voltage of solenoid valve: AC 220V;

7. The detection device is composed of a projectile, a launching device, a velocity measuring device and a passive pressure box

8.The wood block is pine or softwood, dry density is 500kg/m3±25kg/m3, the cross-section height is 38mm±1mm, width is 89mm±1mm. One end of the wood block specimen is called the impact end, and the other end is the end;

【Product Features】

This device uses two photoelectric sensors of the same model to record the time when the emitter passes through the two sensors through an electronic timer. The response frequency of the electronic timer is not less than 10KHz, and the reaction time is not more than 0.15ms. The velocity of the emitter is calculated as the distance between the two photoelectric sensors divided by the time counted by the electronic chronometer.
