Table B
Made syrup belongs to the colour grade mentioned in Column I of Table A if its light transmission percentage is the one mentioned in Column II, determined at the wavelength of 560 nm with a spectrophotometer equipped with optical cells with parallel windows of 10 mm path length, using as a reference glycerol with an analytical purity representing 100% of transmission.
