Key value for chemical safety assessment

Additional information

A10: In accordance with section 1, Annex XI of Regulation (EC) 1907/2006 (REACH), the study does not need to be conducted. Testing of flammability is not considered to be required for inorganic metal salts in which (i) the cation is in a high and stable oxidation state (e.g. Sb3+) and which therefore is incapable of further reaction with oxygen, and (ii) the anionic component is similarly not capable 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).

A11: In accordance with Regulation No 1907/2006 Annex XI a test according to A.11 (flammability; gases) is not considered to be required, since the substance is a solid powder with a melting point of 68.4°C and a boiling point of 267.3°C, and therefore not a gas at room temperature.

A12: 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 (in accordance with section 1, Annex XI of Regulation (EC) 1907/2006 (REACH)).

A13: Testing for pyrophoric properties of solids is not considered to be required, since this substance is stable at ambient temperature. This substance also 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) . Furthermore, long-term industrial experience in handling shows that the substance does not ignite in contact with air (in accordance with section 1, Annex XI of Regulation (EC) 1907/2006 (REACH)).
