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
