Division 5.2.1 Refractometer having a graduated scale showing refractive indices

Read from Table 2 the percentage by mass of sucrose which corresponds to the value obtained from 4.2, corrected, if necessary, by 5.1 (a). The soluble solids content is equal to the number thus found. The result should be taken to be the arithmetical average of the two determinations provided the conditions for repeatability (see 5.3) are met. Express the result to one decimal place.
