- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods
- Remarks:
- VDI 2263, Part 1
Cross-reference
- Reason / purpose for cross-reference:
- reference to same study

- Guideline:
- other: Directive VDI 2263, Part 1
- Relative self-ignition temperature:
- >= 140 °C
- Remarks on result:
- other: result refers to the pure test substance
- Relative self-ignition temperature:
- >= 160 °C
- Remarks on result:
- other: result refers to the kieselgur mixture (1:1)
- Conclusions:
- Due to the results from the Grewer-Oven screening test further studies are necessary to exclude or classify the substance as self-heating substance according to Regulation (EC) No 1272/2008.
In the screening test according to Grewer with the pure product an endothermal effect was observed in the temperature range 40 - 140°C. At 140°C the beginning of self-heating was recorded. A multistage reaction was observed which led to a maximum temperature of more than 450 °C.
In the screening test with the kieselguhr mixture 81:19 self-heatiing was detected starting at 160°C. A multistage reaction was observed which led to a maximum product temperature of more than 500°C.

- Key result
- Test procedure:
- other: burning index according to VDI 2263
- Remarks on result:
- other: burning index BZ 4
- Remarks:
- glowing without sparks (smoldering) or slow decomposition without flame
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- ca. 63 min
- Remarks on result:
- other: derived based on burning time for 50 mm
Any other information on results incl. tables
The product showed a smouldering fire when an ignition source (flame or hot wire) was applied at ambient temperature. A propagation of the combustion was observed. The product did not melt.
The combustion behaviour of the product at ambient temperature is characterized by the burning index BZ 4 (glowing without sparks (smoldering) or slow decompostion without flame).
Due to the fact that a propagation of the combustion was observed the burning rate had to be determined.
Due to the low burning rate the test was stopped after 15.75 min/50 mm. Derived burning time for a distance of 200 mm: 63 min. The burning time was far above the limit of 2 min for 200 mm. Therfore, the main test to determine the burning rate did not have to be performed.
Applicant's summary and conclusion
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- Combustion Number (BZ) 4 was determined. The burning time was far above the limit of 2 min for 200 mm.
Therefore, the substance has not to be classified as flammable solid according to Regulation (EC) No 1272/2008.
