چکیده

The mass value of the weights that are unit's standard must be determined correctly, especially for E<sub>0</sub> no 74 as national working standard. Sub-division is method commonly used to determine these weights. sub-division involved three in this study, namely Pt-Ir K-112, 74, and 75. was measuring standard, while class were test check both based on Pt-Ir, which analyzed using weighted least squares method. calibration obtained values 75 1000,000046 g 1000,000163 g, respectively. In measurement, uncertainty becomes a very important part being stated. 0.036 mg.
