- Conclusions:
- The test item has not to be classified as self-heating substance according to Regulation (EC) No 1272/2008, Annex I, 2.11.4
In the screening test according to Grewer with the pure test substance an exothermal effect starting at 270°C was observed. A multi-step reaction led to a maximum product temperature of 560°C.
In the screening test with the kieselgur mixture (1:1) an exothermal effect starting at 270°C was observed. A multi-step reaction led to a maximum product temperature of 540°C.

- Remarks:
- measurement at 100°C
- Remarks on result:

- Remarks:
- burning with flame or spark generation
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- the substance has not to be classified as flammable solid according to Regulation (EC) No 1272/2008.
No propagation of combustion was recorded during the measurement at room temperature and the combustion behaviour was assessed burning index BZ 3 (localized combustion or glowing with practically no spreading)
Due to the fact that propagation of the combustion was not observed the burning rate did not need to be determined.
Independent fire spread was observed after an ignition source (flame or hot wire, 2 min) was applied at 100°C.
The combustion behaviour of the product at ambient temperature is characterized by the burning index BZ 5 (burning with flame or spark generation)

- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods with acceptable restrictions
- Remarks:
- According to appendix R7-1 of ECHA Guidance on Information Requirements and Chemical Safety Assessment multiple techniques should be applied to investigate phys. chem. properties of particulates, although different measurement methods may not provide comparable results. Laser diffraction is the well experienced standard procedure for pigments to determine particle size distribution of the pigment as it is manufactured and delivered.
- Reason / purpose for cross-reference:
- reference to same study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- ISO 13320 (Particle size analysis - Laser diffraction methods)
- Principles of method if other than guideline:
- Particle size determination by laser diffraction.
- Type of method:
- Laser scattering/diffraction
- Type of distribution:
- volumetric distribution
- Percentile:
- D10
- Mean:
- 0.66 µm
- St. dev.:
- 0.05
- Percentile:
- D50
- Mean:
- 6.6 µm
- St. dev.:
- 0.86
- Percentile:
- D90
- Mean:
- 21.4 µm
- St. dev.:
- 4.3
Given standard deviation is based on the general experience with the method and pigments. The estimated values are typical standard deviations for pigments:
D10: 4 % of D10 (minimum value 0.05 µm)
D50: 13 % of D50 (minimum value 0.1 µm)
D90: 29 % of D90 - D50
the test material was sieved prior to measurement (mesh size 2000 µm). About 21 % (w/w) coarse grain remained on the sieve. All values above relate to the sieved material.
D50 of unsieved test material is about 9 µm.
