The test shall be carried out at a temperature of 23±2°C (73±1.2°F)and a relative humidity of 50±5%.
  1. Measure the coating thickness minimal 3-45 μm (.039 - 1.77 mils) (according to the Buchholz
    Table)
  2. The coating to be tested must be smooth and clean.
  3. Use the level gage to ensure the test panel is at level on the testing surface.
  4. Use the template to mark the spot to be measured and the feet positions on the test object. The
    indentation will be visible at the gap in the middle.
  5. Check the indentation body (weight, wheel and fixing points) and make sure they are free from
    dust.
  6. Gently, and without tilting or lateral movements, place the indentation body on the test panel, feet
    first, exactly on the marked positions, then lower the indenter carefully until it touches the panel and
    start T1 on the timer.
  7. After 30 seconds remove the Buchholz Indentation Tester from the surface and start T2 on the timer.
    While removing be careful not to apply any pressure to the indenter.
  8. After the recovery period of 35 seconds measure the length of the indentation (L) with the measur-
    ing microscope.
  9. Look up the indentation length (L) in the Buchholz table and find the corresponding Buchholz
