Rui Mingyang from the Changchun Institute of Metrology and Testing Technology introduced the specific experimental process of analyzing the uncertainty caused by the repeatability of the melting point apparatus in his paper "Uncertainty Analysis and Evaluation of Melting Point Apparatus", and the final processing Uncertainty mathematical model of melting point apparatus. The test is based on the national metrology verification regulations JJG701-2008 "melting point Tester" verification regulations.
