Administrative data
- Endpoint:
- relative self-ignition temperature (solids)
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
Cross-referenceopen allclose all
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1992
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Study has been performed according to German guidelines by an independent laboratory.
- Qualifier:
- according to guideline
- Guideline:
- other: VDI 2263, Blatt 1: "Staubbrände und Staubexplosionen, Gefahren - Beurteilung - Schutzmaßnahmen; Untersuchungsmethoden zur Ermittlung von sicherheitstechnischen Kenngrößen von Stäuben"
- GLP compliance:
- not specified
- Specific details on test material used for the study:
- 400-mesh powder (<30 µm) as commercially available
- Key result
- Test procedure:
- other: screening test
- Remarks:
- VDI 2263
- Remarks on result:
- other: Flammability class
- Remarks:
- BZ2
- Interpretation of results:
- non flammable
- Conclusions:
- According to the results of the evaluation on burning behaviour, BZ2 has been assigned to calcium hexaboride powder and BZ4 has been assigned to CaB6 filter dust. Based on the burning behaviour of CaB6 in this test, it can be concluded that CaB6 as commercialized does not have to be classified as highly flammable. No labelling is required for CaB6.
- Executive summary:
The test was performed under a German national guideline (VDI 2263) by an authority involved in occupational safety. The method is considered a suitable screening level flammability test under CLP. The result is deemed reliable with restrictions and suitable for Classification & Labeling.
Specific observation on the dusts were not provided. Commercial calcium boride powder was assigned a flammability class of BZ2. Filter dust (not commercially available) was assigned a flammability class of BZ4.
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Endpoint:
- melting point/freezing point
- Type of information:
- not specified
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Principles of method if other than guideline:
- no data
- GLP compliance:
- no
- Type of method:
- other: no data
- Key result
- Melting / freezing pt.:
- 2 235 °C
- Remarks on result:
- other: no data on pressure
- Conclusions:
- The melting point of CaB6 is reported as 2235 °C.
- Executive summary:
The melting point of CaB6 is reported as 2235 °C. Because this data is available in a handbook, it is considered reliable with restrictions.
