- Principles of method if other than guideline:
- The density of the liquid resin was determined by pycnometry as prescribed in e.g. ASTM 1475-98. A stainless steel pycnometer (ZEHNTNER density cup ZPM3030, 50 cm3) is preferred for light-sensitive resins
- GLP compliance:

- Density:
- 1.061 g/cm³
- Temp.:
- 23 °C
- Conclusions:
- Under the study conditions, the density of the test substance was determined to be 1.061 g/cm3 (pycnometer method).
- Executive summary:
A study was conducted to determine the density of the test substance according to ASTM 1475-98 (pycnometer method). A stainless steel pycnometer (50 cc) was preferred for light-sensitive resins. The mass of the calibrated pycnometer was determined using an analytical balance. The vessel was subsequently filled with 50 mL of resin and the mass was again determined in order to calculate the density of the liquid. Under the study conditions, the density of the test substance was determined to be 1.061 g/cm3 (Boutreau, 2016).
