Use the table difference found below that density to calculate the density ρt of the spirit at that temperature T in whole degrees.\nUsing the whole temperature line, calculate the difference between density ρ′ in the table immediately above ρt and the calculated density ρt. Divide that difference by the table difference found to the right of density ρ′. The quotient provides the decimal portion of the alcoholic strength while the integer of the alcoholic strength is found at the top of the column in which density ρ′ is found (Dt, the alcoholic strength).\nNote 4:\nAlternatively keep the pycnometer in a water bath maintained at 20 °C (± 0,2 °C) when making up to the mark.\nA.4.2.1.4.\nResult\nUsing the density ρ20 calculate the real alcoholic strength using the alcoholic strength tables identified below:\nThe table giving the value of the alcoholic strength by volume (% vol) at 20 °C as a function of the density at 20 °C of water-alcohol mixtures is the international table adopted by the International Legal Metrology Organisation in its Recommendation No 22.\nA.4.2.2.
