The Dutch TQC SP1880 drop weight impact testing machine is a special testing equipment used to test the impact resistance and flexibility of coatings. The SP1880 drop weight impact testing machine has dual scales and a special indicator to ensure that the distance of each impact test is in compliance with the standard. Additionally, for correct positioning, a level is built in.
The maximum test plate thickness of the SP1880 drop weight impact testing machine is 45mm.
SP1880 drop weight impact testing machine complies with ISO 6272-2:2002, ASTM D 2794:2004, JIS K 5600-5-3:1989, EN 12206-1:2004, EN 13523-5:2001, AAMA 2605-05, Qualicoat 2006, Qualisteelcoat 2008 and other standards.
* The standards that meet the requirements depend on the type of impact testing machine, and other standards can be applied by changing the device combination.
1) Check whether the SP1880 drop weight impact testing machine is placed horizontally, whether all components are installed correctly and a punch of appropriate diameter is selected.
2) Press the red button to raise the punch and place the test sample on the mold base.
3) Gently lower the weight onto the punch and adjust the guide tube. The 0 mark on the guide tube should be kept level with the bracket of the drop weight.
4) Make sure that the punch can be raised when the red button is pressed and the drop weight can slide freely on the pipe.
5) Adjust the height limit ring, and adjust the weight to the corresponding scale line in the conduit according to the height required for the test.
6) Raise the drop weight and lock it with the release clamp.
7) In a safe state, release the release clamp to allow the weight to fall.
8) Press the red button to take out the test sample.
9) Check the coating.
10) The operation test can be repeated according to the actual situation.
