Abstract : The object of this article is to present the angular reference plate developed by the BNM-LNE. After having presented the angular standards we draw the purposes to reach for an angular reference instrument. The principle of two encoders- errors elimination is presented with the solution carried out to free itself from under sampling defaults inherent to this measuring principle. Presentation of the assessment of uncertainties and its result of a standard uncertainty of ± 0.04- for the measurement of angular polygons are validated by the participation at the comparative survey EUROMET 371

Keywords : Angular metrology errors elimination standards
