Abstract

In order to prove the method of experiment Differential Scanning Calorimeter equipment from Setaram was valid , it a research about verification of the Setaram method used ASTM method No E-399-402/1992, E-1269-1990 and used standard material Certificate Reference Material Sn, Pb,Zn, and Al. Analysis of heat capacity has been performed using step and continuous method in temperature range 30 oC until 450oC with heating rate 3oC/minute.Result of analysis show that step and continuous method from Setaram was valid for analysis heat capacity of sample Pb, Zn, and Al because the deviation , precision and accuracy obtained can be accepted because the value is appropriate with ASTM, while analysis heat capacity of sample Sn hasn’t valid because the deviation, precision and accuracy obtained is in appropriate with ASTM. From the result of heat capacity and than calculated uncertainty to understand the value of uncertainty experiment of heat capacity sample standard Sn, Pb, Zn dan Al are 9,273;2,597; 4,54 ; 1,423 J/moloC
