Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010 - 2011
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Guideline compliant study with good documentation, the atmospheric pressure was not reported.
- Qualifier:
- according to guideline
- Guideline:
- other: Grewer-oven test (VDI guideline 2263, part 1, 1990)
- Deviations:
- no
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Principles of method if other than guideline:
- Using this Grewer-oven solid samples (powdered or granular) of up to five wire mesh baskets (cylindric, V =8 cm³) are simultaneously heated at a rate of 1 K/min in an air stream of 120 l per hour up to about 500 °C. The sample temperature is detected by a thermocouple in the center of the basket and is recorded. It is compared to the temperature of an inert (reference) sample (graphite) which represents the heating ramp of the oven. Exothermic (self-heating) behavior of the sample can be recognized by the lowest temperature ("onset") and by the extent of deviation of the sample temperature from the reference temperature. This test is used as a screening test for quick detection of self-heating under air.
- GLP compliance:
- no
- Key result
- Relative self-ignition temperature:
- 313.6 °C
- Remarks on result:
- other: The air pressure was not provided but since it was explicidly mentioned that it was changed, it can be assumed that the test was performed as normal air pressure.
- Conclusions:
- Iron (II) sulfide can be excluded from the hazard class “self-heating substances”.
- Executive summary:
The auto-flamability of FeS was evaluated following Grewer-oven test (VDI guideline 2263, part 1, 1990). Based on this test the assessment was performed. Only in the case of the beginning of an exothermic reaction <220 °C (assessment criterion) an additional test (UN test N.4, 1 l wire mesh cube, storage temperature 140 °C) would have been necessary. Otherwise no further test is necessary and the sample can be excluded from the hazard class “self-heating substances”.The Grewer-oven test showed the beginning of an exothermic reaction at about 313.6 °C. Therefore no further testing was necessary because the classification criterion was not fulfilled. However, the classification for autoflamability according to EU-method A.16 was fulfilled since the temperature increase started at < 400°C.
