The gold standard for calibration and testing laboratories. Requires:

A is a theoretically perfect point, axis, or plane. In reality, datums are simulated by inspection fixtures (datum simulators: surface plates, collets, chucks). Datum shift and material condition modifiers (MMC, LMC) further complicate measurement. metrology engineering
