  • Page 7 4. Measurement 4.1. Performing Measurements 4.1.1. Leeb Testing Procedure (except Leeb U) Select automatic compensation for impact direction “Automatic”, see chapter “3.2.1 Controls”. If “Automatic” is not allowed, set the impact direction (    ). The Equotip Leeb Impact Devices DL doesn’t support automatic mode. The impact direction must be selected manually. Select the appropriate material group, hardness scales and number of impacts per measurement series.
  • Page 8 measurement series are displayed. NOTE! Make sure the loading tube is allowed to slowly return back to the starting position. Do take care so the loading tube does not spring back uncontrolled, which may result in permanent device damage. NOTE! If possible, follow the standard practice of Leeb rebound hardness testing as described in the standards ISO 16859-1 (metallic materials), ASTM A956 (steel, cast steel and cast iron only), or other applicable standards.
  • Page 9 4.1.2. UCI Testing Procedure 1. Place the probe on the sample to test. The probe must be perpendicular to the surface (± 5°). The special foot can be used to increase repeatability and reduce distortion of the results, see chapter “14. Ordering Information”. 2.

  • Page 13 4.3.1. Equotip Leeb D/DL 4.3.1.1. Test Principle During measurement with Equotip 540 impact devices (D, DL); an impact body with a ball indenter is launched by spring energy against the sample to be measured, and then rebounds. Before and after the impact, a permanent magnet inside the impact body passes through a coil in which a voltage signal is induced by the...
  • Page 14 4.3.1.2. Sample Preparations Keep the sample free of vibrations during the test. Light and thin parts must be specially fastened, see chapter “3.3.1.6 Testing Light Samples”. Ensure that the surface of the work piece is clean, smooth and dry. If required, use appropriate cleaning agents for cleaning, such as acetone or isopropanol. Do not use water or any other detergent fluids.
  • Page 15 4.3.1.4. Test Conditions To ensure proper hardness readings, the following conditions must be fulfilled. If one or more conditions are not met, the measurement result may be significantly false. Impact device type D/DL Roughness grade class ISO 1302 Surface Max. roughness depth Rt (μm / μinch) 10 / 400 preparation Average roughness Ra (μm / μinch)
  • Page 16 4.3.1.5. Testing Light Samples If the samples are lighter than specified in chapter “3.3.1.4 Test Condi- tions” or sample sections have unfavorable mass distribution they can vibrate as the impact body hits the test point. This results in unwanted energy absorption. Such samples shall be supported by solid worktops. If the mass falls below the specific requirements but still exceeds the coupling amount then coupling it to a larger mass can help prevent vibra- tions.
  • Page 17 • The original HLDL-HB conversion curve for “1 Steel and cast steel” is now adapted using the two data points. The detailed procedure on how to create custom conversion curves in the Equotip 540 is given in chapter “6.4 Conversion Curve Creation”.
  • Page 18 In contrast, hardness scale conversions are correct only when the appropriate material group is selected. Free online material databases and the Equotip 540 on-board reference documents can be useful to assign your materials to one of the default material groups. Suitability of conversions should be qualified on calibrated samples before use.

  • Page 20 4.3.2. Equotip Ultrasonic Contact Impedance (UCI) 4.3.2.1.Test Principle The UCI method uses the same pyramid-shaped diamond as a conventional Vickers hardness tester. Unlike Vickers testing, no optical evaluation of the indentation is required, enabling fast and portable measurements. The UCI method excites a rod into an ultrasonic oscillation. The test load is applied by a spring and typically ranges from 1 to 10 kg of force (HV1 –...

  • Page 22 The Equotip 540 offers for this a fast and easy way. Once the hardness value is converted to Vickers, it can be further converted to any other available hardness unit according to either the ASTM E140 or the ISO 18265.
  • Page 23 your instrument is fully operational and you can now continue with your measurements. NOTE! The performance check should be done regularly before using the instrument to verify the mechanical and electronic functions of the probe and the indicating device. This requirement is also included in the relevant hardness standards, see chapter “13.
