- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks on result:
- other: No exothermic reaction observed; Test item temperature not exceeded 200 °C (i.e. rise >60 °C above oven temperature); thus considered negative response; no changes in appearance of test item; test item considered ‘not self-ignitable’
- Remarks on result:
- other: No exothermic reaction observed; Test item temperature not exceeded 200 °C (i.e. rise >60 °C above oven temperature); thus considered negative response; no changes in appearance of test item; test item considered ‘not self-ignitable’
- Conclusions:
- The substance is considered 'not self-ignitable'.

Additional information
- Baltussen E (2010). Determination of physico-chemical properties of 202026/C. Testing laboratory: NOTOX B.V., 's-Hertogenbosch, The Netherlands. Report no. 492704. Owner company: ReachCentrum SPRL, P-I236 AlFe REACH Consortium (Iron Salts sub-consortium), Brussels, Belgium.
Testing for this endpoint has been waived in accordance with column 2 restrictions. The submission item category members do not contain elements such as carbon and hydrogen necessary for auto flammability in air.
A recent, reliable screening test for self-heating conducted in accordance with UN method N.4 has demonstrated that the solid salt form of ferrous sulphate gives a negative result. The salts is non-self-ignitable (at 140 °C using the modified Bowes-Cameron cage test), which is as expected for non-combustible inorganic substances (Baltussen, 2010 study 492704).
