- 20 °C
- Conclusions:
- The relative density of HAT ISO was tested in a pycnometer method according to EU Guideline A 3. The relative density D 20/4 of HAT ISO was determined to be 0.828.
- Executive summary:
The relative density of a test article is the ratio between the mass of a volume of the test article at +20 °C and the mass of the same volume of water at +4 °C.
The relative density of the test article was determined by a pycnometer method. A pycnometer about 10 mL (Ref. 453) was used. The test was carried out at 20 °C.
The relative density D 20/4 of HAT ISO was determined to be 0.828.
Reference
The relative density is obtained by the formula
D T/4 = M(T) test article / M(T) water x VM (T) water / VM (4 °C) water
T : temperature of test
M: mass
VM : volumetric mass of the water:
at 20 °C: VM (20 °C) water = 998.2071
at 4 °C: VM (4 °C) water = 999.9750
The different values of the volumetric mass of water are given in pages F5 - F6 of the "Handbook of Chemistry and Physics2, 60th Edition - 1979 -1980; CRC Press
