Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- Executive summary:
The performance of experimental tests was not necessary.
The sample does not fulfil the criteria of this hazard class because there are no chemical groups associated with explosive properties present in the given molecule of Iron (II) sulfide (judgement based on the UN “Manual of test & Criteria”, Appendix 6, Screening Procedures, point 3.2).
An additional evidence is given with the result of the thermal stability test (Differential Scanning Calorimeter, DSC) which shows only a low energy potential with regard to decomposition. The result was decomposition energy of -63.3 J/g (exotherm). In the case of an explosive substance the exothermic decomposition energy is much higher (e.g. organic substances: >-500 J/g).
Reference
The performance of experimental tests was not necessary. The sample does not fulfil the criteria of this hazard class because there are no chemical groups associated with explosive properties present in the given molecule of Iron (II) sulfide (judgement based on the UN “Manual of test & Criteria”, Appendix 6, Screening Procedures, point 3.2).
An additionally evidence is given with the result of the thermal stability test (Differential Scanning Calorimeter, DSC) which shows only a low energy potential with regard to decomposition. With the differential scanning calorimetry the heat flow between the (filled) sample crucible and a reference crucible (filled with an inert material or left empty) is measured as a function of the oven temperature and of time. From the recorded heat-flow/time signal the enthalpy of the decomposition reaction (endothermic or exothermic) can be determined.The so-called onset temperature marks the beginning of a thermal effect under the conditions of the chosen heating-up conditions. In order to find the onset temperature using the DSC software the program uses a tangent on the steepest slope of a peak (thermal effect) which determines the onset temperature by the resulting osculation point to the extrapolated base line. The result was decomposition energy of -63.3 J/g (exotherm). In the case of an explosive substance the exothermic decomposition energy is much higher (e.g. organic substances: >-500 J/g).

Additional information

Justification for classification or non-classification
The sample does not fulfil the criteria of this hazard class because there are no chemical groups associated with explosive properties present in the given molecule of Iron (II) sulfide (judgement based on the UN “Manual of test & Criteria”, Appendix 6, Screening Procedures, point 3.2).
Hence. no classification and labelling is needed according to GHS and CLP.
