Displaces liquid weight equal to its own weight when the hydrometer, hydrometer is in equilibrium, then the density of the sample It can be read directly from the hydrometer.

4 Instrument

4.1 hydrometer 4.1.1 The following hydrometer can be used to determine the density of the liquid. a) M10008000900NFB35-510; b) M10009001000NFB35-510; c) M10010001100NFB35-510. 4.1.2 When the density of the liquid is outside the range of 0.8g/mL ~ 1.1g/mL, use the same precision hydrometer. 4.2 tube An inner diameter of at least than the outer diameter of the hydrometer 20mm, the height should allow the bottom of the bottom of the hydrometer tube kept to a minimum Distance of 25mm (see NFB35-302). 4.3 Thermometer Accuracy should be in line with STL/0.2/15/45, NFB35-502 requirements.

5 sample preparation

5.1 according to the provisions of NFT30-048 sampling. The sample size should take 5.2 to meet the three tests. Note. The sampling should avoid products containing injected into the test tube bubbles and suspended solids. ......
