Technical Committee for Length

The Technical Committee of Length supports industry and researchers by coordinating and further developing the measurement related to the unit of length, the metre. Technical areas include:

  • Wavelength (frequency) standards
  • Dimensional measurement (length, area, volume)
  • Angle measurement
  • Co-ordinate measurement
  • Measurements for micro- and nano-technology
  • Form measurement (shape, flatness, roundness, cylindricity, straightness)
  • Surface texture
  • Roughness measurement
  • Measurement of complex geometry
  • Calibration of measuring instruments
  • Distance measurement
