Technical specifications
Testing frame:
Testing frame:
- The structure frame raw materials: Steel channel ( approx the width ≥100mm )
- The frame used welded or securely bolted at the cone to minimize twisting during impact
- It's use the bolted to the floor to prevent movement during impact testing
- The inner dimension of test frame: 2015mm×996mm (It’s adjustable, suit for different dimension of pv modules
- The sample frame with the rubber bar and the thickness is 3mm, wide 15mm, hardness shore A50°
- Impactor
1.The exterior of the bag according to the standard use the wrapped with tape
2. The inner filling diameter 2.5-3.0mm ( the material is pellets or steel ball )
3. The mass of impactor :45.5 ± 0.5kg
4. The ratio of widest diameter to height is between 1:1,5 to 1:1,4 - 5. The Impactor figures please see as below:
Safety Function
1. With the safety protection frame
2. Anti-secondary impact function
Testing parameter
1. Impact height: 300mm , 450mm, 600mm, 750mm, 900mm, 1200mm
2.Impact height display accurate: 0.1mm
2. Impactor rise ways: Automaitc rise/ Jog rise
4. Release ways: arriving predetermined height, the cylinder automatic release
5. Real-time display rise height
6.Touch screen control and display
7.Before release delay warning function- Testing procedure
- At rest the impactor bag shall hang no more than 13mm from the surface of the pv module sample and no
- More than 50mm from the centre of the pv module sample
- Lift the impactor to a drop height of 300mm from the surface of the pv module sample, allow the impactor to stabilize and then release it to impact the pv module sample
