Results and discussion
Relative self-ignition temperature (solids)
- Remarks on result:
- other: Following a preliminary screening test, it was concluded that copper (I) sulphide is not likely to auto-ignite.
Any other information on results incl. tables
At about 240.5 °C the beginning of an exothermic reaction was observed. According to the UN “Transport of Dangerous Goods, Manual of tests & Criteria”, Annex 6, point 5.2.2, the classification procedure for self-heating substances need not be applied if the result of a suitable screening test (e.g. Grewer-oven, VDI 2263) shows an onset temperature of 80 K above the reference temperature of 140 °C (reference temperature is related to the conditions of the 1 l wire mesh cube test at 140 °C). Therefore additional tests are only necessary in the case of an onset temperature of < 220°C.
Applicant's summary and conclusion
- Conclusions:
- Following a preliminary screening test, it was concluded that copper (I) sulphide is not likely to auto-ignite.
