適用范圍：1.1 This standard includes Table 1 and three inter-conversion charts ( Fig. 1 to 3 ) intended for use in the inter-conversion of various units used in the estimation of percentages of ethanol in ethanol-water mixtures.1.1.1 Table 1 shows the inter-relationship between:a) specific gravity in air at 15·6°/15·6°C,b) percentage of British proof spirit,c) percentage of ethan,ol by weight,d) percentage of ethanol by volume at 15·6°/15·6°C,e) percentage of US proof spirit, andf) specific gravity in vacuum at 150/15°C.1.1.2 The values in Table 1 and the three charts [ Fig. 1 to 3 (p. 69-71)] are calculated by rounding approximately to the fourth decimal places in the case of specific gravities and to the second decimal places in the case of other units.
