This part of ISO 14253 specifies concepts and terms for evaluating the uncertainties of the test values derived according to a test protocol agreed upon by the parties and relative to instrument indication(s), obtained in verification testing of GPS indicating measuring instruments. When a test of an indicating measuring instrument comprises several test values, some relative to the instrument indication and some to other metrological characteristics, this part of ISO 14253 is concerned with the uncertainty of the former only. The responsible German standardization committee is Working Committee NA 152-03-02 AA "CEN/ISO Geometrische Produktspezifikation und Prüfung" ("CEN/ISO Geometrical product specifications and verification") at DIN Standards Committee Technical Fundamentals (NATG).
