Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: UN Test N.4 Self-heating substances
- GLP compliance:
- yes (incl. QA statement)
- 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 - Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- As the Grewer oven test indicated no self-ignition up to 470 °C the test item had not to be classified as “self-heating substance” in the sense of UN Manual of Tests and Criteria, Method N.4., and had not to be classified as “self-heating substance” according to chapter 2.11 of the GHS (CLP) regulations.
- Executive summary:
Winkler (2021) is a GLP-compliant study following UN method N4 and can be used as a key study for this endpoint.
'Aluminium, magnesium and silicon oxides and hydroxides from refinement of aluminium salt slag residues' had not to be classified as “self-heating substance” in the sense of UN Manual of Tests and Criteria, Method N.4., and had not to be classified as “self-heating substance” according to chapter 2.11 of the GHS (CLP) regulations.
Reference
6.7 g of the test item were placed into the wire-basket.
The temperature of the test item followed behind the oven temperature starting at an oven temperature of approx. 20 °C. At an oven temperature of approx. 40 °C an endothermal effect started. A second endothermal effect was observed at an oven temperature of approx. 220 °C. No exothermal effect was observed up to a temperature of approx. 470 °C. After the test the test item appeared visually unchanged.
As no self-ignition temperature was observed up to 470 °C (final oven temperature) further testing is not necessary.
Description of key information
not self-heating
Key value for chemical safety assessment
Additional information
'Aluminium, magnesium and silicon oxides and hydroxides from refinement of aluminium salt slag residues' had not to be classified as “self-heating substance” as a Grewer oven test indicated no self-ignition up to 470 °C of the test item.
