Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 265-997-9 | CAS number: 65996-66-9 The thermally agglomerated substance formed by heating a variable mixture of finely divided coke, iron ore, blast furnace dust, steelmaking dust, mill scale, other miscellaneous iron-bearing materials, limestone, and dolomite at 1315°C to 1482°C (2400°F to 2700°F).

Link to relevant study record(s)
- Endpoint:
- oxidising 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 incapable of reacting exothermically with combustible materials

Description of key information
In accordance with Regulation (EC) No 1907/2006 (REACH), Annex VII, section 7.13, column 2, a study for oxidising properties does not need to be conducted if the substance is incapable of reacting exothermically with combustible materials. This is the case for iron sinter, as explained in detail in the justification attached to the endpoint study record. In brief: the main constituents of iron sinter are the iron oxides Fe2O3 and Fe3O4. Their reduction (i.e. the oxides becoming oxidising) is an endothermic process requiring a strong reducing agent and elevated temperatures. Thus, the iron oxides are incapable of reacting exothermically with combustible materials, and do not have oxidising properties as per the classification criteria in the CLP regulation and in the UN Test O.1.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
The substance "iron sinter" does not need to be classified according to CLP Regulation (EC) No 1272/2008 since it is incapable of reacting exothermically with combustible materials.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
