Results and discussion
Relative self-ignition temperature (solids)
- Key result
- Remarks on result:
- no self ignition observed under the test conditions
Any other information on results incl. tables
A negative result was obtained. No spontaneous ignition occurred and no exothermic effect of the test item was observed. It demonstrated that the test item is “not a self-heating substance”. According to the UN guideline, no further testing is required.
After the experiment, the consistency of the sample was unchanged, i.e. no reaction and/or decomposition of the test item was observed.
Applicant's summary and conclusion
- Conclusions:
- Self-heating of Basic red 51 was determined in accordance with UN Test N.4 “Test Method for Self-heating Substances”.
From the negative result obtained at 140°C using a 10 cm sample cube, it was concluded that Basic red 51 is not a self-heating substance. - Executive summary:
The test item was exposed to air at 140°C using a temperature controlled laboratory oven, a cubic stainless steel wire 10 cm sample container, NiCr/Ni thermocouples and a temperature recording device.
A negative result was obtained. No spontaneous ignition occurred and no exothermic effect of the test item was observed. It demonstrated that the test item is “not a self-heating substance”. According to the UN guideline, no further testing is required.
