The Technical Committee of Length (TC-L) is concerned with technical issues which are important to industry and researchers 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.
