- Executive summary:
The density of iron sulfide was determined accroding to OECD 109 and EEC A.3 at 29.2°C with two replicates using a helium pygnometer. The density at 20 °C was determined to be of 4.806 g*cm-3 (=4806 kg*m-3) and the relative density is 4.806.
The obtained value is considered relevant and reliable.
Reference
The volume of a sample of this solid with 15.0178 and 18.9344 g (3.1288 and 3.9457 cm³ , respectively) was measured in helium in a calibrated cylinder.
Two independent measurements were performed at 29.2 °C with following results: 4.7999; 4.7987 g*cm-3. The mean value was : 4.806·g*cm-3 (corrected to 20°C).
The density at 20 °C was determined to be of 4.806 g*cm-3 (=4806 kg*m-3) and the relative density is 4.806.
Description of key information
4.806 g/cm3
Key value for chemical safety assessment
- Relative density at 20C:
- 4.806
Additional information
The density of FeS was determined in a non-GLP Klimisch 1 key study (Paß 2011) according to methods OECD 109 and EEC A.3 at 29.2 °C using a helium pygnometer. The results were corrected for 20°C. The density was determined to be of 4.806 g*cm-3(=4806 kg*m-3). The corresponding relative density is 4.806.
The obtained values are considered relevant and reliable.
