Endpoint:

substances / mixtures which in contact with water emit flammable gases

Remarks:

contact with water

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

Reference 3

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

Description of key information

Flammability (Pyrophoric): In accordance with Regulation (EC) 1907/2006 (REACH), Annex XI, Section 1, the study does not need to be conducted. Testing of flammability is not considered to be scientifically required for silver iodide, which is an inorganic metal salt consisting of Ag+ and I- ions in a crystalline matrix. Therefore, this substance is intrinsically not combustible and therefore also not considered to be flammable.

Flammability (in contact with water): Testing of 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)).

Flammability (solid): Testing of flammability is not considered to be required for silver iodide. Silver iodide is an inorganic salt and does not contain any structural moieties that could burn. Silver iodide is intrinsically not combustible and can safely be assumed not to be ignitable in contact with a flame. This substance can thus be designated as non-flammable (in accordance with section 1, Annex XI of Regulation (EC) 1907/2006 (REACH)).

Key value for chemical safety assessment

Flammability:

non flammable

Justification for classification or non-classification

Testing of flammability is not considered to be scientifically required for silver iodide, which is an inorganic metal salt consisting of Ag+ and I- ions in a crystalline matrix. Therefore, this substance is intrinsically not combustible and therefore also not considered to be flammable. No hazard classification for flammability is required.
