The invention relates to a fluid product meant for the calibration of sintered parts and to a process for preparing the same. According to the invention, the fluid product comprises 15 ... 17 % distilled naphthenic acids, 3 ... 4 % triethanolamine, 20 ... 22% castor oil, 14 ... 16 % chlorinated paraffin, 8 ...9 .% red oil and 35 ...40 % white spirit, the percentage being expressed by weight. According to the invention, the process for preparing the fluid product consists in the following steps: stirring the distilled naphthenic acids with triethanolamine for 15 ... 20 minutes, introducing the castor oil, the chlorinated paraffin and the red oil into the reaction while stirring the reaction mixture for 15 ... 20 minutes, heating at a temperature of 50 degree C, stirring for 15 minutes, followed by the cooling of the reaction mass down to a temperature of 30 degree C, adding the white spirit and stirring further for 30 minutes.
