Angle, Form and Complex Geometry

The length measuring technique comprises among others also measurand known as “form and position” as well as the plane angle. The BEV covers a small field of this subject field. These are especially:

Angle

  • Cone gauges (internal and external)
  • Bubble levels
  • Bevel protracto

Form

  • Optical flat
  • Optical parallel
  • Surface plate
  • Straight edge
  • Depth-, groove-, step height standards (ISO 5436-1 Typ A, e.g.)
  • Thread plug
  • Thread ring
  • Ball bar
  • Analytic sieves
  • Measuring microscopes
