Key result
Test procedure:
other: burning index according to VDI 2263
Remarks on result:
other: burning index BZ 2
Remarks:
brief ignition and rapid extinction

The product showed only short burning when an ignition source (flame or hot wire, 2 min) was applied at ambient temperature. Rapid extinction and no 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 2 (brief ignition and rapid extinction) . The same behaviour was recorded for the measurement at 100°C.

Due to the fact that no propagation of the combustion was observed the burning rate did not need to be determined.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
Combustion Number (BZ) 2 was determined.
Therefore, the substance has not to be classified as flammable solid according to Regulation (EC) No 1272/2008.

Remarks on result:
other: mean of 2 measurements

Typically measurements under air show a signal with about - 20 J/g due to chemical reaction of the test substance with residual oxygen. This effect is not considered for the assessment.

A signal with - 30 J/g was recorded between 230 - 270°C.

the test material starts to decompose with an onset temperature of 320°C (330°C, nitrogen), peak 352°C (359°C, nitrogen)

no endothermal process (melting) was recorded

decomposition energy 210 J/g (air) and 190 J/g (nitrogen)

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.

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

A multimodal particle size distribution was observed. The first peak at about 1.5 µm, the second (main) peak at about 7 µm and the third one (small) at about 65 µm.

Any other information on results incl. tables

In the screening test according to Grewer with the pure test substance an exothermal effect starting at 280°C was observed, which led to a maximum product temperature of 630°C.

In the screening test with the kieselgur mixture (1:1) an exothermal effect starting at 300°C was observed. Self-heating led to a temperature of 725 °C.
