CCM.M-K4 is a key international comparison organized by the Bureau International des Poids et Mesures (BIPM) to verify the measurement ability of 1kg stainless weights. This paper reports the process analysis of mass determination of CCM.M-K4 during the measurement in NIM, China. The gravity correction and air bouncy correction are discussed, and the measuring uncertainties of measurement process are evaluated. Mass difference between the test standards is 0.0015 mg, and average mass of both test standards is 0.013 mg. The standard uncertainty of test weights is 0.013 mg.
