Model overview

• Steel (S-16)

• Wood (S-17)
  Made from grade A1 birch plywood sanded on both sides, 6.35 mm (0.25 inch). 100 mm square with a 6.35 mm centre hole.
• Aluminium (S-18)
  Made from 19-gauge aluminium (5052). 100 mm square with rounded corners and a 6.35 mm centre hole.

  High-quality flat glass, approx. 3.15 mm thick. 100 mm square with a 6.35 mm centre hole.

NOTE: If you are preparing your own test panels, make sure the sides are flat and parallel. A simple way to check flatness is to place a ruler across the surface of the test panel and check that there is no gap. Use a file to remove any burrs from the centre hole and edges.

Two standardisation plates are offered which are used to determine the abrasion properties of certain Taber abrasives. These include:

• Zinc (S-34)
  Rolled zinc sheet with a thickness of approx. 0.8 mm. Used to check the wear rate of sandpaper strips such as S-42. Note that the S-34 zinc sheet should not be used for more than 10 calibrations per side. 100 mm square with a 6.35 mm centre hole.
• Plexiglass (S-38)
  Moulded acrylic glass for evaluating the abrasion properties of the material used with the Taber Grit Feeder Attachment sand used. 100 mm square with a 6.35 mm centre hole and protective film on both sides.
