Procedure:

• i) Clean, dry and weigh the specific gravity bottle along with the stopper (Weight ‘A’).
• ii) Fill the specific gravity bottle with freshly boiled distilled water and insert the stopper firmly. Keep it in the water bath having a temperature of 27.0 + 1oC for not less than half an hour and weigh it (Weight ‘B’).
• iii) Weigh the specific gravity bottle about half-filled with the material (Weight ‘C’).
• iv) Weigh the specific gravity bottle about half-filled with the material and the other half with distilled water (Weight ‘D’).
• v) Weigh the specific gravity bottle completely filled with the material (Weight ‘E’).
