Paper Abstract

A measurement based on error separation was used to measure the inside and outside squareness of the square. In the measurement, one squareness measuring system was used as the main standard whose error could be separated and eliminated. So this method could improve the accuracy of the measurement results. The uncertainty of measurement results are evaluated using the method in Aplac Interlaboratory Comparison Proficiency Testing Program M026 Calibration of Square, and referring to ISO/IEC Guide 98-3-2008.
