Impact Tester NOVOTEST STRIKE-U6272

The device is designed for determining the strength of paint films (coatings) under impact of 1 kg load or other loads.

The design of the device STRIKE-U6272 is made to comply with modern requirements of ISO 6272-2002.

The device can be used in factory laboratories for coatings testing during manufacturing processes, as well as in field conditions during maintenance work.

The instrument is used for testing coatings on metals, plastics, flooring, wood panelling, ceramic, glass, concrete, screed samples.

The device measures the maximum height, in free fall with a certain mass of the load that does not cause visible mechanical damage on the surface of the tested plate with a lacquer coating. The strength of coatings at impact determined as the maximum height in centimetres at which the load of 1 kg firing pin falls freely to the surface being tested in accordance with ISO 6272 or ASTM D 2794.

The device has several versions, which comply to different standards.

Also instrument has simple and very reliable design.

Operating

 

Operating method

The tests can be performed in two ways:

  • By principle destroyed / not destroyed, when the test is performed at set up height and a certain weight of sinker (test coating for compliance with the specific requirements)
  • Test for define the minimum drop height with a gradual increasing the height of the falling and the minimum weight of sinker at which the coating was cracked or exfoliated from the painted surface

 

Testing

Install the required sinker at the desired height. If necessary, use required restrictors to limit the depth of the indentation. Put the tested plate outside (direct hit) or inside (back side hit) on the anvil cover. Holding the tested plate at this position by a presser coupling. Release the sinker and allows it to fall on the tested plate, which is lying on the anvil. After that inspect the coating with the magnifying glass.
