Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Reaction of the test substance in contact with air is tested (spontaneous ignition - yes or no). Test method is applicable for liquids and solids. Test method is not applicable for substances, that have to be exposed to air for hours or days or at higher temperatures, before they ignite.
- GLP compliance:
- no

- other: substance is not pyrophoric
Applicant's summary and conclusion
- Conclusions:
- The study was performed comparable to guideline study with acceptable restrictions and therefore reliability of Klimisch 2 has been assigned. No ignition has been observed in six separate testings and hence, the result is negative (not pyrophoric).
- Executive summary:
Reaction of the test substance in contact with air is tested (spontaneous ignition - yes or no). For the test, 1 to 2 cm3 of the powdery substance to be tested is poured from circa 1 m height onto a non-combustible surface and it is observed whether the substance ignites during dropping or within five minutes of settling. The test is performed six times unless ignition occurs.
No ignition has been observed in six separate testings and hence, the result is negative (substance is not pyrophoric).
Only a slow colour change of the test substance from orange-brown to dark brown has been observed. Further, one filling emitted smoke.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
