- Specific details on test material used for the study:
- The test item was mixed prior to the study by the test facility in equal parts from the following three subsamples:
Subsample 1:
Supplier: Befesa Aluminio S.L
Carreta Luncaha- Asúa 13
48950 Erandio (Vizcaya), Spain
Batch No.: Paval Nov 2020
Appearance: Grey solid
Storage conditions: Ambient temperature (10 °C to 30 °C)
Expiry date: November 19, 2021
Subsample 2:
Supplier: RAFFMETAL SPA
Via Malpaga 82
25070 Casto (BS), Italy
Batch No.: Rapal01 Nov 2020
Appearance: Grey solid
Storage conditions: Ambient temperature (10 °C to 30 °C)
Expiry date: December 16, 2021
Subsample 3:
Supplier: Intals SPA
Via Schievano 7
20100 Milano (MI), Italy
Batch No.: Argalum Dec 2020
Appearance: Grey solid
Storage conditions: Ambient temperature (10 °C to 30 °C)
Expiry date: January 11, 2022 - Type:
- relative density
- Density:
- 2.317 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item at 20 °C (compared to water at 4 °C) according to the European Commission Regulation (EC) No. 440/2008 and in the OECD 109 was determined to be 2.32.
- Executive summary:
Winkler (2021) is a GLP-compliant study following OECD guideline 109 and EU method A3. It is reliable without restrictions and can be used as a key study for this endpoint. Density was determined with the gas comparison pycnometer. The relative density of the test item at 20 °C (compared to water at 4 °C) was determined to be 2.32.
Reference
Two test series were performed at 20 °C. The results are summarized in Table 1.
Table 1: Results of the two tests
Measurement | Density rP20 / g / cm3 |
1 | 2.3171 |
2 | 2.3174 |
Mean | 2.3173 |
Mean density rPR for the two test series: 2.32 g/cm3
Description of key information
The relative density of the test item at 20 °C (compared to water at 4 °C) was determined to be 2.32.
Key value for chemical safety assessment
- Relative density at 20C:
- 2.32
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
