The following tables show the conversion between refractive index resp. density to Brix at 20°C. Refractive Index (1) (1) According to 16th Session of ICUMSA 1974 . Density (2) (2) Specific gravity according to 109 of NBS Circular 440. Definition of Density .
Table 3.2 Density and refractive indexes of sucrose. Title. Table 3.2 Density and refractive indexes of sucrose. Author. Sabeeha Merchant. Created Date. 4/4/2017 1:38:36 PM.
Table A2.2 Sugar content and density of saturated aqueous sucrose solutions as a function of temperature (Antokolskaya et al. 1964 ) . Temperature ( ° C) Sugar (g/100 g water) Density (kg/m 3 )
Both NBS and ASBC converted to apparent specific gravity at 20 °C/20 °C. The ICUMSA tables are based on more recent measurements on sucrose, fructose, glucose and invert sugar, and they tabulate true density and weight in air at 20 °C against mass fraction.
Table for comparison of degrees Brix (percent by weight of pure sucrose in pure solutions), degrees Baumé (modulus 145), specific gravity at 20/4°C, and specific gravity at 20/20°C is given in 942.33 (see Appendix C).
The tables of viscosities of sucrose solutions appearing in NBS. Circular 440 were calculated, assuming the value of the viscosity of. water at 20° C to be 1.0050 centipoises. Subsequently, a redetermina- tion of the absolute viscosity of water at 20° C established the value 1.0020 centipoises.
Brix reading expresses the soluble solids content of the solution in terms of a Brix value corresponding to a pure sucrose solution of the same specific gravity. The final Brix measurement of liquid packing media in canned fruit and similar products depends
