Overview
The Dutch TQC drop ball impact tester SP1891 is an imported drop ball impact tester designed and manufactured according to international standards ISO 6272-1 and ASTM D2974. It is suitable for testing the anti-Impact performance of paints, coatings, etc. The instrument base has a built-in bubble level to ensure the correct placement. The catheter has dual scales and has been approved by Qualicoat, QIB and GSB laboratories for testing.
Features
1. The base has a built-in bubble level to ensure the correct placement
2. Conduit with dual scale design
3. Accredited with Qualicoat, QIB and GSB laboratory testing
4. Interchangeable device combinations to meet different standard requirements
5. Equipped with height limiting ring and a variety of specifications weight, punch
Principle
The impact test instrument freely drops a specific mass of drop weight from a set height. Impact test the surface of the sample to evaluate its anti-Impact performance according to the damage of the sample. The instrument uses direct Impact mode to precisely control the drop height of the drop weight through a height limiting ring.
Applications
Impact test of paints and coatings
Standards
ISO 6272:1993、EN 12206-1:2004、AAMA 2605-05、Qualicoat 2006、Qualisteelcoat 2008
Steps
1. Select the appropriate heavy head for experimental testing
2. Place the punch on the bracket on the floor panel
3. Put the height restriction ring over the catheter
4. Push the height limit ring and weight to the bottom, turn the height limit ring lever to block the weight
5. Tighten the fixing button to fix the height limit ring
6. Install the height limiting ring and weight catheter on the assembly substrate
7. Hold the weight, turn the lever to loosen the height limit ring, and raise the height limit ring to the starting height required for the test test
8. Press the red button, raise the punch, and place the test plate on the base
9. When turning the handle to release the catheter, hold the catheter. Move the catheter until the weight line and the 0 scale line of the catheter are online horizontally
10. At this time, the ball impact test instrument SP1981 is installed
Notice
• To be placed on a horizontal surface
• Have a free height of at least 2.2 meters on the work surface
Humidity of the test environment should meet the standards
