Geometrical product specifications (GPS) - Systematic errors and contributions to measurement uncertainty of length measurement due to thermal influences
ISO/TR 16015:2002 defines procedures for the determination of errors, appropriate corrections and the evaluation of measurement uncertainty contributors due to thermal influences in the performance of length measurements for geometrical product specification (GPS) when broader analyses, such as those in accordance with the methods of ISO/TS 14253-2, show that thermal effects are significant contributors to the measurement uncertainty, systematic error or both.
