- Endpoint:
- substances / mixtures which in contact with water emit flammable gases
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Conclusions:
- Flammability on contact with water: Testing of flammability in contact with water is not considered to be required because the substance does not contain any chemical groups that react with water or damp air leading to the generation of dangerous amounts of highly flammable gases. Experimental testing for solubility brought up further evidence that gases are not formed when this pigment is in contact with water (in accordance with section 1 of REACH Annex XI).
Furthermore, long-term industrial experience in practical handling of the substance shows that it does not react with water and will not ignite with water or humid air. - Endpoint:
- pyrophoric solids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
- Conclusions:
- Pyrophoricity: Testing for pyrophoric properties is not considered to be required for this pigment as this substance is stable at ambient temperature. This substance does not contain any chemical groups that might lead to spontaneous ignition a short time after coming in contact with air at room temperature (circa 20°C) (in accordance with section 1 of REACH Annex XI).
Furthermore, long-term industrial experience in handling shows that the substance does not ignite spontaneously (i.e. the autoignition temperature is not below room temperature). - Endpoint:
- flammable solids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Conclusions:
- Flammability of solids - oxides: In accordance with section 1 of REACH Annex XI, the study does not need to be conducted. Considering that this pigment was produced by high temperature calcination, testing of flammability is not considered to be required. Cations contained in the pigment are in the highest possible oxidation state, and the pigment is therefore incapable of further reaction with oxygen. This substance can thus be designated as non-flammable (Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, section R.7.1.10.3).
Furthermore, long-term industrial experience in handling shows that the substance is not flammable.

Description of key information
Testing of flammability does not appear scientifically necessary:
-Testing of flammability of solids (A.10) is not considered to be required, since the cations contained in the pigment are in the highest possible oxidation state, and the pigment is therefore incapable of further reaction with oxygen.
- Testing for flammability in contact with water (A.12) is not considered to be required, because the substance does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable.
- Testing of pyrophoric properties of solids and liquids (A.13) is not considered to be required, since the substance is stable at ambient temperature. It does not contain any chemical group that might lead to spontaneous ignition a short time after coming in contact with air at room temperature (approx. 20 °C).
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Flammability:
According to the `ECHA Guidance on the Application of the CLP Criteria (July 2017) section 2.7.4: Classification of substances and mixtures as flammable solids´ indicate, that a test according to EU Method A.10 (flammability of solids), does not need to be conducted:
“…For inorganic material, testing may be waived in cases where the substance is commonly known to be not flammable (i.e. stable salts or metal oxides) or where a flammability hazard can be excluded by any other scientific reasoning…”.and “…For inorganic solids, the classification as flammable is rather rare…”.
High-temperature calcination products of diiron trioxide and amorphous silica resulting in a glassy silica matrix is an inorganic pigments, with the metal cations contained therein, being in the highest possible oxidation state, therefore the pigment is incapable of further reaction with oxygen. Furthermore, the pigment was produced by high temperature calcination and long-term industrial experience in handling shows that the pigment is not flammable.
Phyrophoric properties:
The study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied. Furthermore, long-term industrial experience in handling shows that the substance does not ignite spontaneously in contact with air
Flammability in contact with water:
Testing for flammability in contact with water is not considered to be required, because the substance does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable. Furthermore, long-term industrial experience in practical handling of the substance shows that it does not react with water, and recent experimental testing for water solubility has also not reported any formation of gases.
Justification for classification or non-classification
High-temperature calcination products of diiron trioxide and amorphous silica resulting in a glassy silica matrix does not need to be classified according to CLP Regulation (EC) No 1272/2008 since it is not highly flammable.
